OC 中常用UI控件的简单设置

**lable标签**

UILabel *lab = [[ UILabel alloc ] init];

lab. frame = CGRectMake (75, 50, 150, 50);

lab. backgroundColor = [ UIColor purpleColor ]; 颜色

lab.text = @" 欢迎来到一品中国 " ;内容

lab.textAlignment = NSTextAlignmentCenter ; 文本布局

lab.font = [ UIFont systemFontOfSize :18];字体

lab.textColor = [ UIColor orangeColor];字体颜色

lab.shadowColor = [ UIColor darkGrayColor ]; 阴影偏移量

lab. shadowOffset = CGSizeMake (2, 2);

lab. numberOfLines = 0; 行数

**button**

UIButton *btn1 = [ UIButton  buttonWithType : UIButtonTypeInfoLight ];

btn1. center = self . window . center ; 按钮中心

btn1.bounds = CGRectMake(0, 0, 50, 50);坐标

[btn1  setTitle: @"Move" forState: UIControlStateNormal];显示字符和按键类型

btn1.backgroundColor = [ UIColor redColor]; 按钮周边颜色

[btn1 addTarget:selfaction:@selector(btnClick)forControlEvents:UIControlEventTouchUpInside];

 

**行动表**

UIActionSheet *sheet = [[ UIActionSheet alloc ] initWithTitle : @" 下载 " delegate : nil cancelButtonTitle : @"Cancel" destructiveButtonTitle : @"Save" otherButtonTitles : @"Other" , @"Other1" , @"Other2" , nil ];

**textfield文本框**

UITextField *textField = [[ UITextField alloc ] init ];

textField. borderStyle = UITextBorderStyleBezel ;文本框类型!!必须设置

textField. secureTextEntry = YES ;安全输入

  _view4.alpha = 0.5; 透明度 0.0 （完全透明） ~1.0 （完全不透明）

 _view4.hidden = YES; 设置隐藏

textField. keyboardType = UIKeyboardTypeNumberPad ;键盘类型

textField. frame = CGRectMake (40, 100, 100, 40);坐标

**图片**

UIImageView *imgView = [[ UIImageView alloc ] initWithImage :[ UIImage imageNamed : @"2.jpg" ]];

imgView. frame = [[ self window ] bounds ];

[imgView setFrame : CGRectMake (50, 50, 50, 50)];

**scrollView**

// 设置 scrollView 的滑动范围 .

scroll. contentSize = CGSizeMake (220*5, 0);

//设置scrollView的分页[设置滑动一个单位的宽或者高]

scroll.pagingEnabled =YES;

//设置scrollView横向的显示条Horizontal横

scroll.showsHorizontalScrollIndicator =NO;

//Vertical 竖

scroll.showsVerticalScrollIndicator =NO;

//设置回弹

scroll.bounces =NO;

// 设置 x.y 向负方向的偏移量

scroll.contentOffset =CGPointMake(0, 0);

//设置scroll的代理方法

//开启代理之后对象就会自动执行该对象里面的代理方法

//属性赋值也是调方法

    scroll.delegate =self;

**动画使用方法**

 [ UIView beginAnimations : nil context : nil ];//开始

  [UIViewsetAnimationDuration:3]   //执行时间

 [ UIView setAnimationDelegate : self ];代理

 [ UIView setAnimationCurve : UIViewAnimationCurveLinear ];//移动方式

//  动画结束方法

 [UIViewsetAnimationDidStopSelector:@selector(animaitonFinished)];

     _vi.center =self.window.center;

  [UIViewcommitAnimations];//结束

**警告框使用方法**

UIAlertView *alertView = [[ UIAlertView alloc ] initWithTitle : @" 温馨提示 " message: @" 动画结束了 " delegate: nil cancelButtonTitle : @"Cancel" otherButtonTitles: @"OK" , nil ];

[alertView show ];

**选项卡**

NSArray *itemsArr = @[ @" 联系人 " , @" 通话 " , @" 我的 ” ];//数组

UISegmentedControl *seg = [[ UISegmentedControl alloc ] initWithItems :itemsArr];

seg.frame =CGRectMake(60, 50, 200, 40);//坐标

seg. selectedSegmentIndex = 0; 设置默认第一个选项被选中

seg. tintColor = [ UIColor orangeColor ];

[seg addTarget : self action : @selector (segClick:) forControlEvents : UIControlEventValueChanged ];//调方法

[self.viewaddSubview:seg];//添加到View上
