IOS开发控件视图day17：给一个UIView对象添加点击事件

1、创建手势

UIView *view1 = [[UIView alloc]init];

 UITapGestureRecognizer * tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(event:)];

2、添加到view1中

//设置需要连续点击几次才响应，默认点击1次
[tapGesture setNumberOfTapsRequired:1];
//添加到view1中
[view1 addGestureRecognizer:tapGesture];

3、手势响应函数

-(void)event:(UITapGestureRecognizer *)gestuer
{
  
}
