UIButton的使用

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    _window = [[UIWindow
alloc] initWithFrame:[UIScreen
mainScreen].bounds];

    _window.backgroundColor = [UIColor
whiteColor];

    [_window
makeKeyAndVisible];

    

    /*----------------------UIButton的使用------------------------*/

//    //创建按钮

    //如果用这种方法，无法设置类型

//    UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(100, 50, 100, 50)];

//    //设置按钮的类型

//    button.buttonType = UIButtonTypeRoundedRect;

    

    UIButton *button = [UIButton
buttonWithType:UIButtonTypeRoundedRect];

    //设置显示的地方和大小

    button.frame =
CGRectMake(100,
50, 100, 50);

    

    //设置背景颜色

//    button.backgroundColor = [UIColor redColor];

    //设置标题，设置标题一定要绑定状态

    //设置普通状态显示的标题

    [button setTitle:@"按钮"
forState:UIControlStateNormal];

    //设置点击(高亮)状态显示的标题

    [button setTitle:@"点我了"
forState:UIControlStateHighlighted];

    //设置标题的颜色

    [button setTitleColor:[UIColor
redColor] forState:UIControlStateNormal];

    [button setTitleColor:[UIColor
greenColor] forState:UIControlStateHighlighted];

    

    

    //按钮标题字体

    button.titleLabel.font = [UIFont
systemFontOfSize:15];

    //文本位置<
e758
/span>

    button.titleEdgeInsets =
UIEdgeInsetsMake(0,
0, 0, 0);

    //偏移量

    button.imageEdgeInsets =
UIEdgeInsetsMake(0,
0, 0, 0);

    //设置按钮的圆角属性

    button.layer.cornerRadius =
5;

    //添加按钮的点击事件

    //UIControlEventTouchDown:按钮点击下的那一个事件就被触发了

    //UIControlEventTouchDownRepeat按钮被多次点下的时候执行事件

    //UIControlEventTouchDragInside
按钮被按着拖拽的时候被执行

    //UIControlEventTouchUpInside 
按钮被点击后松开  执行事件，常用的

    [button addTarget:self
action:@selector(buttonAction:)
forControlEvents:UIControlEventTouchUpInside];

    //设置button的tag值

    button.tag = 1;

    //添加到视图上显示

    [_window addSubview:button];

    

    //创建一个系统样式的按钮

    UIButton *button1 = [UIButton
buttonWithType:UIButtonTypeContactAdd];

    button1.frame =
CGRectMake(100,
100, 50, 50);

    button1.tag =
2;

    //添加一个点击事件

    [button1 addTarget:self
action:@selector(buttonAction:)
forControlEvents:UIControlEventTouchUpInside];

    [_window addSubview:button1];

    /*-----------------------自定义按钮的使用-----------------------*/

    

    //创建一个按钮

    UIButton *customButton = [UIButton
buttonWithType:UIButtonTypeCustom];

    //设置frame

    customButton.frame =
CGRectMake(220,
200, 80, 40);

    

    //创建两个图片

    UIImage *image1 = [UIImage
imageNamed:@"back_on_black.png"];

    UIImage *image2 = [UIImage
imageNamed:@"back_on.png"];

    

    //设置button显示的图片,则按钮的标题不会出现了

    //http://blog.csdn.net/u012762130/article/details/42591983

//    [customButton setImage:image1 forState:UIControlStateNormal];

//    [customButton setImage:image2 forState:UIControlStateHighlighted];

//禁用按钮，此时按钮的图片颜色会变浅

//    button.enabled = NO;

    

    //如果想显示图片还显示标题，则用一下方法

    [customButton setBackgroundImage:image1
forState:UIControlStateNormal];

    [customButton setBackgroundImage:image2
forState:UIControlStateHighlighted];

    //设置标题

    [customButton setTitle:@"按钮"
forState:UIControlStateNormal];

    [customButton setTitle:@"摸我了"
forState:UIControlStateHighlighted];

    

    button.userInteractionEnabled =
NO;//交互事件

    //设置点击事件

    [customButton addTarget:self
action:@selector(customAction)
forControlEvents:UIControlEventTouchUpInside];

    

    [_window addSubview:customButton];

 

    return
