iOS笔记--简单的格式使用

1.常用的代理方法套路
@class UserModel;
@protocol UserOperationDelegate
// 所有的点击都绑在这个代理方法

-(void)IconImageViewTapped:(int)userId ;
-(void)LikeButtonClicked:(UIButton *)button;
@end
@interface UserOperationView : UIView
@property (nonatomic , strong) iddelegate;
@property (nonatomic, strong) UserModel *userModel;
@end

2.常用的Block定义套路

3.常用的枚举定义套路

4.常用的主视图窗口套路

    ViewController* vc = [[ViewController alloc]init];
    UINavigationController * nav =[[UINavigationController alloc]initWithRootViewController:vc];
    self.window.rootViewController = nav;
    [self.window makeKeyAndVisible];

5.常用的一些宏定义

#define ScreenBounds                [[UIScreen mainScreen]bounds]
#define ScreenHeight [UIScreen mainScreen].bounds.size.height
#define ScreenWidth [UIScreen mainScreen].bounds.size.width
#import 
#import 
#define MainColor [UIColor colorWithRed:14/255.0 green:84/255.0 blue:113/255.0 alpha:1.0]
#define BackColor [UIColor colorWithRed:235/255.0 green:235/255.0 blue:235/255.0 alpha:1]

//  系统版本
#define iOS7 ([[UIDevice currentDevice].systemVersion doubleValue] >= 7.0)
//  邮箱注册
#define RegisterWithEmailAndPwd(tel,pwd)      [NSString stringWithFormat:@"http://192.168.1.108:8080/batManage/User/register.action?user.userEmail=%@&user.userPwd=%@",tel,pwd];

6.常用的添加手势方法

//单击，双击，捏合，长按
    UITapGestureRecognizer* singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    UITapGestureRecognizer* doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];
    UITapGestureRecognizer* twoFingerTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTwoFingerTap:)];
    UILongPressGestureRecognizer * longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];
    singleTap.numberOfTapsRequired = 1;
    singleTap.numberOfTouchesRequired = 1;
    doubleTap.numberOfTapsRequired = 2;
    twoFingerTap.numberOfTouchesRequired = 2;
    [self.view addGestureRecognizer:singleTap];
    [self.view addGestureRecognizer:doubleTap];
    [self.view addGestureRecognizer:twoFingerTap];
    [self.view addGestureRecognizer:longPress];
    [singleTap requireGestureRecognizerToFail:doubleTap];
 -(void)handleSingleTap:(UITapGestureRecognizer *)gestureRecognizer{}
 -(void)handleDoubleTap:(UITapGestureRecognizer *)gestureRecognizer{}
 -(void)handleTwoFingerTap:(UITapGestureRecognizer *)gestureRecongnizer{}
 -(void)longPress:(UIGestureRecognizer*)gestureRecongnizer{}

7.常用的延迟操作

 double delayInSeconds = 5.0;
 dispatch_time_t popTime =    dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
//do SomeThing...
 });

8.常用的路径设置

$(SRCROOT)/TestDemo/PrefixHeader.pch

9.区分Label不同区域的颜色方法

    UILabel * label = [[UILabel alloc]initWithFrame:CGRectZero];
    NSString* str1=@" 联系邮箱";
    NSString* str2=@"(选填)";
    NSMutableAttributedString *mutableText = [[NSMutableAttributedString alloc]initWithString:[NSString stringWithFormat:@"%@%@",str1,str2]];
    NSRange rangetext = [[mutableText string] rangeOfString:str2];
    [mutableText addAttribute:NSForegroundColorAttributeName value:[UIColor lightGrayColor] range:rangetext];
    label.attributedText=mutableText;
    label.font=[UIFont systemFontOfSize:18];

10.无扩展情况下的快速创建方法

-(void)createLabel
{
    UILabel *label=[[UILabel alloc]initWithFrame:CGRectMake((self.view.frame.size.width-140)/2, 390, 140, 21)];
    label.text=@"暂不支持第三方账号登录";
    label.textColor=[UIColor grayColor];
    label.textAlignment=NSTextAlignmentCenter;
    label.font=[UIFont systemFontOfSize:14];
    [self.view addSubview:label];
}

-(UITextField *)createTextFielfFrame:(CGRect)frame font:(UIFont *)font placeholder:(NSString *)placeholder
{
    UITextField *textField=[[UITextField alloc]initWithFrame:frame];
    
    textField.font=font;
    
    textField.textColor=[UIColor grayColor];
    
    textField.borderStyle=UITextBorderStyleNone;
    
    textField.placeholder=placeholder;
    
    return textField;
}

-(UIImageView *)createImageViewFrame:(CGRect)frame imageName:(NSString *)imageName color:(UIColor *)color
{
    UIImageView *imageView=[[UIImageView alloc]initWithFrame:frame];
    
    if (imageName)
    {
        imageView.image=[UIImage imageNamed:imageName];
    }
    if (color)
    {
        imageView.backgroundColor=color;
    }
    
    return imageView;
}

11.字符串的编码，解码

+(NSString*)encodeString:(NSString*)unencodedString{
    
    // CharactersToBeEscaped = @":/?&=;+!@#$()~',*";
    // CharactersToLeaveUnescaped = @"[].";
    
    NSString *encodedString = (NSString *)
    CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,
                                                              (CFStringRef)unencodedString,
                                                              NULL,
                                                              (CFStringRef)@"!*'();:@&=+$,/?%#[]",
                                                              kCFStringEncodingUTF8));
    
    return encodedString;
}
 
//URLDEcode
-(NSString *)decodeString:(NSString*)encodedString
 
{
    //NSString *decodedString = [encodedString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding ];
 
    NSString *decodedString  = (__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL,
                                                                                                                     (__bridge CFStringRef)encodedString,
                                                                                                                     CFSTR(""),
                                                                                                                     CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
    return decodedString;
}

12.保持TableVIewCell的某一个单元格选中状态

  1.[_tableView selectRowAtIndexPath:self.selectIndex animated:YES scrollPosition:UITableViewScrollPositionNone]//（TableView设置）
2.        
self.selectionStyle=UITableViewCellSelectionStyleGray;//（）

13.显示手机的网络菊花

    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
