我们都知道，UIButton的点击事件：添加一个addtarget,然后选择点击触发：UIControlEventTouchUpInside，就可以实现Btn的点击事件。...imageView的点击事件 -->探究3：为啥ImageView 没有 UIbutton 的addtarget方法？ ?...addTarget方法底层 如图，我们发现addTarget并不是所有的类都有这个方法-->只有UIControl的子类才能有这个方法！ ?...UIButton继承自UIControl，所以有addTarget方法 ?...UIImageView不继承UIControl，所以没有addTarget方法 -->探究4：没有addTarget方法的ImageView如何添加点击事件？ 答：使用手势。 ?
有另一种方法 // 首先给textfield添加addTarget方法，注意最后的controlEvents是EditingChanged [self.accountTextField addTarget...selector(handleTextDidChange:) forControlEvents:UIControlEventEditingChanged]; [self.passwordTextField addTarget
触发了这个事件以后，执行butClick:这个方法，addTarget:self 的意思是说，这个方法在本类中也可以传入其他类的指针 [button1 addTarget:self action:@selector...forControlEvents:UIControlEventTouchUpInside]; //显示控件 [self.view addSubview:button1]; 注意： [button1 addTarget...:self action:@selector(alarmTimeDone:) forControlEvents:UIControlEventTouchUpInside]; addTarget:self
