IOS开发简单登录LoginViewController、注册RegisterViewController、UcenterViewController功能实现方法

一、个人中心未登录

方法:

      加判断登录状态直接打开个人中心页面4，否则出现上面引导登录或注册入口显示

代码如下:

    

#pragma mark addView
- (void)addView
{
    //背景图
    [self.view setBackgroundColor:[UIColor whiteColor]];
    UIImageView *loginImgTips = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"login_tips.png"]];
    loginImgTips.frame = CGRectMake(33, 31, 255, 135);
    [self.view addSubview:loginImgTips];
    [loginImgTips release];
    
    //登录、注册提示
    UILabel *loginLab = [[UILabel alloc] initWithFrame:CGRectMake(55, 43, 199, 80)];
    [loginLab setText:@"登录工程师爸爸，网站收藏、iPhone下载、可方便哩!"];
    [loginLab setTextColor:[UIColor blackColor]];
    [loginLab setBackgroundColor:[UIColor clearColor]];
    [loginLab setNumberOfLines:3];
    [loginLab setFont:[UIFont systemFontOfSize:18]];
    [self.view addSubview:loginLab];
    [loginLab release];
    
    //登录
    UIButton *loginBtn = [[UIButton alloc] initWithFrame:CGRectMake(37, 180, 117, 37)];
    [loginBtn setBackgroundImage:[UIImage imageNamed:@"Button_login.png"] forState:UIControlStateNormal];
    [loginBtn setBackgroundImage:[UIImage imageNamed:@"[email protected]"] forState:UIControlStateHighlighted];
    [loginBtn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    [loginBtn setTag:101];
    [self.view addSubview:loginBtn];
    [loginBtn release];
    
    //注册
    UIButton *registerBtn = [[UIButton alloc] initWithFrame:CGRectMake(164, 180, 117, 37)];
    [registerBtn setBackgroundImage:[UIImage imageNamed:@"Button_reg.png"] forState:UIControlStateNormal];
    [registerBtn setBackgroundImage:[UIImage imageNamed:@"[email protected]"] forState:UIControlStateHighlighted];
    [registerBtn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    [registerBtn setTag:102];
    [self.view addSubview:registerBtn];
    [registerBtn release];
}

二、登录

顶部导航代码：

#pragma mark addNavBar
-(void) addNavBar
{    
    //返回按钮
    UIButton *btnLeft = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 24, 24)];
    [btnLeft setBackgroundImage:[UIImage imageNamed:@"item_back.png"] forState:UIControlStateNormal];
    [btnLeft setBackgroundImage:[UIImage imageNamed:@"[email protected]"] forState:UIControlStateHighlighted];
    [btnLeft setTag:101];
    [btnLeft.titleLabel setFont:[UIFont boldSystemFontOfSize:14]];
    [btnLeft addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *navBarBack = [[UIBarButtonItem alloc] initWithCustomView:btnLeft];
    [btnLeft release];
    
    [self.navigationItem setLeftBarButtonItem:navBarBack];
    [navBarBack release];
    
    //右侧完成
    UIBarButtonItem *navBarFinish = [[UIBarButtonItem alloc] initWithTitle:@"注册" style:UIBarButtonItemStyleDone target:self action:@selector(btnClick:)];
    navBarFinish.tag = 102;
    self.navigationItem.rightBarButtonItem = navBarFinish;
    [navBarFinish release];
}

登录界面代码实现如下:

#pragma mark addView
//创建输入框
- (void)addInput
{
    //基本参数定义
    CGFloat padx   = 80.0f;
    _vFrame        = CGRectMake(10, 14, 300, 80);
    UIFont *lpFont = [UIFont boldSystemFontOfSize:16];

    //邮箱和密码背景颜色设置
    _view = [[UIView alloc] initWithFrame:_vFrame];
    _view.layer.cornerRadius = 8.0;
    _view.layer.borderWidth = 1;
    _view.layer.borderColor = [UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f].CGColor;
    [_view setBackgroundColor:[UIColor colorWithRed:247.0f/255.0f green:247.0f/255.0f blue:247.0f/255.0f alpha:1.0f]];
    [self.view addSubview:_view];
    [_view release];
    
    //邮箱与密码中间分割线
    UIView *line = [[UIView alloc] initWithFrame:CGRectMake(10, 55, 300, 1)];
    [line setBackgroundColor:[UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f]];
    [self.view addSubview:line];
    [line release];
    
    //用户名或Email
    UIImageView * _eview = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 250, 40)];
    [_eview setUserInteractionEnabled:YES];
    [_view addSubview:_eview];
    [_eview release];
    
    UILabel *_unameLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 5, 55, 40)];
    [_unameLab setText:@"用户名"];
    _unameLab.highlighted = YES;
    _unameLab.highlightedTextColor = [UIColor blackColor];
    [_unameLab setFont:lpFont];
    [_unameLab setBackgroundColor:[UIColor clearColor]];
    [_unameLab setTextColor:[UIColor blackColor]];
    [_view addSubview:_unameLab];
    [_unameLab release];
    
    //用户邮箱
    _email = [[UITextField alloc] initWithFrame:CGRectMake(padx, 15, 200, 40)];
    [_email setBackgroundColor:[UIColor clearColor]];
    [_email setKeyboardType:UIKeyboardTypeEmailAddress];
    [_email setTextColor:[UIColor grayColor]];    
    //[_email setClearButtonMode:UITextFieldViewModeWhileEditing];  //编辑时会出现个修改X
    [_email setTag:101];
    [_email setReturnKeyType:UIReturnKeyNext];  //键盘下一步Next
    [_email setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写
    [_email setAutocorrectionType:UITextAutocorrectionTypeNo];
    [_email becomeFirstResponder]; //默认打开键盘
    [_email setFont:[UIFont systemFontOfSize:17]];
    [_email setDelegate:self];
    [_email setPlaceholder:@"用户名或电子邮箱"];
    [_email setText:@""];
    [_email setHighlighted:YES];    
    [_eview addSubview:_email];
    
    //密码
    UILabel *_passwdLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 43, 45, 40)];
    [_passwdLab setText:@"密  码"];
    [_passwdLab setFont:lpFont];
    _passwdLab.highlighted = YES;
    _passwdLab.highlightedTextColor = [UIColor blackColor];
    [_passwdLab setBackgroundColor:[UIColor clearColor]];
    [_passwdLab setTextColor:[UIColor blackColor]];
    [_view addSubview:_passwdLab];
    [_passwdLab release];
    
    _passwd = [[UITextField  alloc] initWithFrame:CGRectMake(padx, 53, 200, 40)];
    [_passwd setBackgroundColor:[UIColor clearColor]];
    [_passwd setKeyboardType:UIKeyboardTypeDefault];
    [_passwd setBorderStyle:UITextBorderStyleNone];
    [_passwd setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写
    [_passwd setReturnKeyType:UIReturnKeyDone]; //完成
    [_passwd setSecureTextEntry:YES]; //验证
    [_passwd setDelegate:self];
    [_passwd setTag:102];
    [_passwd setTextColor:[UIColor grayColor]];
    [_passwd setFont:lpFont];
    [_passwd setText:@""
    [_view addSubview:_passwd]; 
}

三、注册

顶部导航控制,代码实现如下:

- (void)addNavBar
{
    if (_step == 1) {
        [self setXDNav:YES];
        
        //返回按钮
        UIButton *btnLeft = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 24, 24)];
        [btnLeft setBackgroundImage:[UIImage imageNamed:@"item_back.png"] forState:UIControlStateNormal];
        [btnLeft setBackgroundImage:[UIImage imageNamed:@"[email protected]"] forState:UIControlStateHighlighted];
        [btnLeft setTag:101];
        [btnLeft.titleLabel setFont:[UIFont boldSystemFontOfSize:14]];
        [btnLeft addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
        UIBarButtonItem *navBarBack = [[UIBarButtonItem alloc] initWithCustomView:btnLeft];
        [btnLeft release];
        [self.navigationItem setLeftBarButtonItem:navBarBack];
        [navBarBack release];
        
        //设标题
        [self setXDTitle:@"注册" pageName:@""];
        
        //添加返回按钮
        
        [self addInputOne]; //注册第一步
    }else{
        [self setXDTitle:@"宝贝信息设置" pageName:@""];
                
        //返回按钮
        UIButton *btnLeft = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 24, 24)];
        [btnLeft setBackgroundImage:[UIImage imageNamed:@"item_back.png"] forState:UIControlStateNormal];
        [btnLeft setBackgroundImage:[UIImage imageNamed:@"[email protected]"] forState:UIControlStateHighlighted];
        [btnLeft setTag:101];
        [btnLeft.titleLabel setFont:[UIFont boldSystemFontOfSize:14]];
        [btnLeft addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
        UIBarButtonItem *navBarBack = [[UIBarButtonItem alloc] initWithCustomView:btnLeft];
        [btnLeft release];
        
        [self.navigationItem setLeftBarButtonItem:navBarBack];
        [navBarBack release];        
        
        //右侧完成
        UIBarButtonItem *navBarFinish = [[UIBarButtonItem alloc] initWithTitle:@"完成" style:UIBarButtonItemStyleDone target:self action:@selector(btnClick:)];
        navBarFinish.tag = 102;
        //[_navBarFinish addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
        self.navigationItem.rightBarButtonItem = navBarFinish;
        [navBarFinish release];
        [self addInputTow];
    }
}

注册分两步：

第一步基本信息注册，代码如下

//创建输入框
- (void)addInputOne
{
    //基本参数定义
    CGFloat padx   = 95.0f;
    _vFrame        = CGRectMake(10, 14, 300, 125);
    UIFont *lpFont = [UIFont boldSystemFontOfSize:16];
    
    //邮箱和密码背景颜色设置
    _view = [[UIView alloc] initWithFrame:_vFrame];
    _view.layer.cornerRadius = 8.0;
    _view.layer.borderWidth = 1;
    _view.layer.borderColor = [UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f].CGColor;
    [_view setBackgroundColor:[UIColor colorWithRed:247.0f/255.0f green:247.0f/255.0f blue:247.0f/255.0f alpha:1.0f]];
    [self.view addSubview:_view];
    [_view release];
        
    //用户名与密码中间分割线
    UIView *lineOne = [[UIView alloc] initWithFrame:CGRectMake(10, 53, 300, 1)];
    [lineOne setBackgroundColor:[UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f]];
    [self.view addSubview:lineOne];
    [lineOne release];
    
    //用户名
    UILabel *_unameLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 2, 55, 40)];
    [_unameLab setText:@"用户名"];
    _unameLab.highlighted = YES;
    _unameLab.highlightedTextColor = [UIColor blackColor];
    [_unameLab setFont:lpFont];
    [_unameLab setBackgroundColor:[UIColor clearColor]];
    [_unameLab setTextColor:[UIColor blackColor]];
    [_view addSubview:_unameLab];
    [_unameLab release];
    
    _uname = [[UITextField alloc] initWithFrame:CGRectMake(padx, 10, 230, 40)];
    [_uname setBackgroundColor:[UIColor clearColor]];
    [_uname setTag:101];
    [_uname setUserInteractionEnabled:YES];
    [_uname setKeyboardType:UIKeyboardTypeDefault];
    [_uname setReturnKeyType:UIReturnKeyNext];  //键盘下一步Next
    [_uname setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写
    [_uname setAutocorrectionType:UITextAutocorrectionTypeNo];
    [_uname setReturnKeyType:UIReturnKeyNext]; //下一个Passwd
    [_uname becomeFirstResponder]; //默认打开键盘
    [_uname setFont:[UIFont systemFontOfSize:17]];
    [_uname setDelegate:self];
    [_uname setText:@""];
    [_uname setHighlighted:YES];
    [_view addSubview:_uname];
    
    //密码
    UILabel *_passwdLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 43, 45, 40)];
    [_passwdLab setText:@"密  码"];
    [_passwdLab setFont:lpFont];
    _passwdLab.highlighted = YES;
    _passwdLab.highlightedTextColor = [UIColor blackColor];
    [_passwdLab setBackgroundColor:[UIColor clearColor]];
    [_passwdLab setTextColor:[UIColor blackColor]];
    [_view addSubview:_passwdLab];
    [_passwdLab release];
    
    _passwd = [[UITextField  alloc] initWithFrame:CGRectMake(padx, 53, 200, 40)];
    [_passwd setBackgroundColor:[UIColor clearColor]];
    [_passwd setKeyboardType:UIKeyboardTypeDefault];
    [_passwd setBorderStyle:UITextBorderStyleNone];
    [_passwd setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写
    [_passwd setReturnKeyType:UIReturnKeyNext]; //下一个Email
    [_passwd setSecureTextEntry:YES]; //验证
    [_passwd setDelegate:self];
    [_passwd setTag:102];
    [_passwd setTextColor:[UIColor grayColor]];
    [_passwd setFont:lpFont];
    [_passwd setText:@""];
    [_view addSubview:_passwd];
    
    //邮箱与密码中间分割线
    UIView *lineTow = [[UIView alloc] initWithFrame:CGRectMake(10, 95, 300, 1)];
    [lineTow setBackgroundColor:[UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f]];
    [self.view addSubview:lineTow];
    [lineTow release];
    
    //用户邮箱
    UILabel *_emailLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 82, 280, 40)];
    [_emailLab setText:@"电子邮箱"];
    _emailLab.highlighted = YES;
    _emailLab.highlightedTextColor = [UIColor blackColor];
    [_emailLab setFont:lpFont];
    [_emailLab setBackgroundColor:[UIColor clearColor]];
    [_emailLab setTextColor:[UIColor blackColor]];
    [_view addSubview:_emailLab];
    [_emailLab release];

    _email = [[UITextField alloc] initWithFrame:CGRectMake(padx, 92, 200, 40)];
    [_email setBackgroundColor:[UIColor clearColor]];
    [_email setKeyboardType:UIKeyboardTypeEmailAddress];
    [_email setTextColor:[UIColor grayColor]];
    [_email setTag:103];
    [_email setReturnKeyType:UIReturnKeyDone];  //键盘下一步Next
    [_email setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写
    [_email setAutocorrectionType:UITextAutocorrectionTypeNo];    
    [_email setFont:[UIFont systemFontOfSize:17]];
    [_email setDelegate:self];
    [_email setPlaceholder:@"[email protected]"];
    [_email setText:@""];
    [_email setHighlighted:YES];
    [_view addSubview:_email];
}

第二步完善资源输入，代码实现如下：

//创建输入框
- (void)addInputTow
{
    //基本参数定义
    CGFloat padx   = 100.0f;
    _vFrame        = CGRectMake(10, 10, 300, 125);
    UIFont *lpFont = [UIFont boldSystemFontOfSize:16];
    
    //宝贝小名、宝贝性别、宝贝生日背景颜色设置
    _view = [[UIView alloc] initWithFrame:_vFrame];
    _view.layer.cornerRadius = 8.0;
    _view.layer.borderWidth = 1;
    _view.layer.borderColor = [UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f].CGColor;
    [_view setBackgroundColor:[UIColor colorWithRed:247.0f/255.0f green:247.0f/255.0f blue:247.0f/255.0f alpha:1.0f]];
    [self.view addSubview:_view];
    [_view release];
    
    //宝贝小名和宝贝性别分割线
    UIView *lineOne = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 300, 1)];
    [lineOne setBackgroundColor:[UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f]];
    [self.view addSubview:lineOne];
    [lineOne release];
    
    //宝贝小名
    UILabel *_nicknameLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 2, 75, 40)];
    [_nicknameLab setText:@"宝贝小名"];
    _nicknameLab.highlighted = YES;
    _nicknameLab.highlightedTextColor = [UIColor blackColor];
    [_nicknameLab setFont:lpFont];
    [_nicknameLab setBackgroundColor:[UIColor clearColor]];
    [_nicknameLab setTextColor:[UIColor blackColor]];
    [_view addSubview:_nicknameLab];
    [_nicknameLab release];
    
    _nickname = [[UITextField alloc] initWithFrame:CGRectMake(padx, 13, 180, 40)];
    [_nickname setBackgroundColor:[UIColor clearColor]];
    [_nickname setTag:101];
    [_nickname setUserInteractionEnabled:YES];
    [_nickname setKeyboardType:UIKeyboardTypeDefault];
    [_nickname setReturnKeyType:UIReturnKeyNext];  //键盘下一步Next
    [_nickname setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写
    [_nickname setAutocorrectionType:UITextAutocorrectionTypeNo];
    [_nickname setReturnKeyType:UIReturnKeyNext]; //下一个宝贝性别
    [_nickname becomeFirstResponder]; //默认打开键盘
    [_nickname setFont:[UIFont systemFontOfSize:17]];
    [_nickname setDelegate:self];
    [_nickname setText:@""];
    [_nickname setHighlighted:YES];
    [_view addSubview:_nickname];
    
    //宝贝性别
    UILabel *_sexLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 35, 75, 50)];
    [_sexLab setText:@"宝贝性别"];
    [_sexLab setFont:lpFont];
    _sexLab.highlighted = YES;
    _sexLab.highlightedTextColor = [UIColor blackColor];
    [_sexLab setBackgroundColor:[UIColor clearColor]];
    [_sexLab setTextColor:[UIColor blackColor]];
    [_view addSubview:_sexLab];
    [_sexLab release];

    _segment = [[UISegmentedControl alloc] initWithItems:
                                   [NSArray arrayWithObjects:
                                    @"男",@"女",
                                    nil]];
    _segment.frame = CGRectMake(padx+10, 56, 130, 32);
    _segment.segmentedControlStyle = UISegmentedControlStylePlain;
    _segment.selectedSegmentIndex = 1;
    [self.view addSubview:_segment];
    [_segment release];
    
    //宝贝性别与宝贝生日中间分割线
    UIView *lineTow = [[UIView alloc] initWithFrame:CGRectMake(10, 93, 300, 1)];
    [lineTow setBackgroundColor:[UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f]];
    [self.view addSubview:lineTow];
    [lineTow release];
    
    //宝贝生日
    UILabel *_birthLab = [[UILabel alloc] initWithFrame:CGRectMake(30, 96, 75, 40)];
    [_birthLab setText:@"宝贝生日"];
    _birthLab.highlighted = YES;
    _birthLab.highlightedTextColor = [UIColor blackColor];
    [_birthLab setFont:lpFont];
    [_birthLab setBackgroundColor:[UIColor clearColor]];
    [_birthLab setTextColor:[UIColor blackColor]];
    [self.view addSubview:_birthLab];
    [_birthLab release];
        
    _birthDay = [[UIButton alloc] initWithFrame:CGRectMake(57, 96, 200, 40)];
    [_birthDay setBackgroundColor:[UIColor clearColor]];
    [_birthDay setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [_birthDay setTitle:@"2004-10-09" forState:UIControlStateNormal];
    [_birthDay setTag:104];
    [_birthDay addTarget:self action:@selector(openBirthday) forControlEvents:UIControlEventTouchUpInside];
    [_birthDay setHighlighted:YES];
    [self.view addSubview:_birthDay];
    
    //宝贝信息提示
    UILabel *_babyNote = [[UILabel alloc] initWithFrame:CGRectMake(45, 131, 300, 40)];
    [_babyNote setBackgroundColor:[UIColor clearColor]];
    [_babyNote setTextColor:[UIColor colorWithRed:83.0f/255.0f green:92.0f/255.0f blue:112.0f/255.0f alpha:1.0f]];
    [_babyNote setTag:104];
    [_babyNote setFont:[UIFont systemFontOfSize:14]];
    [_babyNote setText:@"推荐引擎会根据孩子信息进行个性推荐"];
    [_babyNote setHighlighted:YES];
    [self.view addSubview:_babyNote];
    [_babyNote release];
        
    //初始日期选择控件
    _datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0.0, 200.0, 0.0, 0.0)];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];    
    [dateFormatter setDateFormat:@"yyyy-MM-dd"];

    //将当前生日时间设置到日期轮轴上
    _datePicker.date = [dateFormatter dateFromString:_birthDay.titleLabel.text];
    
    //设置为中文显示
    NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"zh_CN"];
    _datePicker.locale = locale;
    [locale release];
    [_datePicker setDatePickerMode:UIDatePickerModeDate];
    
    [_datePicker addTarget:self action:@selector(dataValueChanged) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:_datePicker];
}

三、注册，登录成功后直接进入个人中心页

顶部界面代码实现如下:

#pragma mark addHeadView
- (void)addHeadView
{
    //头像背景设置
    UIView *headView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 84)];
    [headView setBackgroundColor:[UIColor colorWithRed:247.0f/255.0f green:247.0f/255.0f blue:247.0f/255.0f alpha:1.0f]];
    
    //按钮方式添加左侧用头像
    UIButton *headBtn = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 64, 64)];
    [headBtn setBackgroundImage:[UIImage imageNamed:@"Baby_head.png"] forState:UIControlStateNormal];
    headBtn.layer.cornerRadius = 8.0;
    headBtn.layer.masksToBounds = YES;
    [headView addSubview:headBtn];
    [headBtn release];
    [self.view addSubview:headView];
    
    //用户名
    UILabel *unameLab = [[UILabel alloc] initWithFrame:CGRectMake(89, 15, 200, 20)];
    [unameLab setText:@"balbaba"];
    [unameLab setTextColor:[UIColor blackColor]];
    [unameLab setFont:[UIFont boldSystemFontOfSize:16]];
    [unameLab setBackgroundColor:[UIColor clearColor]];
    [headView addSubview:unameLab];
    
    //宝贝头像小图
    UIImageView *iconView = [[UIImageView alloc] initWithFrame:CGRectMake(89, 38, 24, 24)];
    [iconView setImage:[UIImage imageNamed:@"Baby_gender_boy.png"]];    
    [headView addSubview:iconView];
    
    //宝贝昵称
    UILabel *nicknameLab = [[UILabel alloc] initWithFrame:CGRectMake(120, 40, 120, 20)];
    [nicknameLab setText:@"宝贝qgggfgghhjjjk"];
    [nicknameLab setTextColor:[UIColor blackColor]];
    [nicknameLab setFont:[UIFont systemFontOfSize:14]];
    [nicknameLab setBackgroundColor:[UIColor clearColor]];
    [headView addSubview:nicknameLab];
    
    //宝贝生日
    UILabel *birthDayLab = [[UILabel alloc] initWithFrame:CGRectMake(230, 40, 80, 20)];
    [birthDayLab setText:@", 4岁3个月"];
    [birthDayLab setTextColor:[UIColor blackColor]];
    [birthDayLab setFont:[UIFont systemFontOfSize:14]];
    [birthDayLab setBackgroundColor:[UIColor clearColor]];
    [headView addSubview:birthDayLab];
    
    [headView release];
}

分段表格视图实现代码如下:

#pragma mark addTableView
- (void)addTableView
{
    _tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 84, 320, 416) style:UITableViewStylePlain];

注：

    1、注册、登录功能主要是锻练对键盘和输入框UITextField、UISegment及UIPickerView的熟练使用

    2、在注册、登录时顶部导航左、中、右相关的"返回" 、"注册"、"完成"等按钮尽量直接使用系统的的类似下面代码

 [self.navigationItem setLeftBarButtonItem:navBarBack];

  self.navigationItem.rightBarButtonItem = navBarFinish;

  [self.navigationItem.titleView addSubview:segment];

在各个ViewController之间切换和控制。

至此完整的用户注册、登录、进入中心页界面实现就完成了，结合上面的代码实现其它IOS项目App应用的功能和流程上大同小异，需要我们自己根据实际产品业务的要求

做出调整，希望对网友有帮助。
