// 上面几个方法都提到
共同的参数 forState . 这个参数决定了标题、图像或其他属性将在何种状态下显现。你可以编程令按钮在那个状态变化

// typedef NS_OPTIONS(NSUInteger, UIControlState) {

// UIControlStateNormal = 0,
常态

// UIControlStateHighlighted = 1 << 0,
高亮 // used when UIControl isHighlighted is set

// UIControlStateDisabled = 1 << 1,
禁用

// UIControlStateSelected = 1 << 2, // flag usable by app (see below)

// UIControlStateApplication = 0x00FF0000, // additional flags available for application use

// UIControlStateReserved = 0xFF000000 // flags reserved for internal framework use

// };

//默认情况下，在按钮被禁用时，图像会被化得深一点。要禁用这个功能，请将这个属性设置为NO

button.adjustsImageWhenHighlighted =
NO;

//这个属性设置为yes，按钮按下时高亮

button.showsTouchWhenHighlighted =
YES;

//给button添加响应

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

//addTarget:self 是链接到self,一般都这样设置

//action:@selector(alarmTimeDone:) 时间处理函数

//forControlEvents:UIControlEventTouchUpInside
控件事件处理的消息

//设置是否能与用户交互
