给手势UITapGestureRecognizer添加"tag"

UITapGestureRecognizer是没有tag属性，但他有UIView的属性，我们可以通过给UIView添加tag属性，从而标记UITapGestureRecognizer。

- (void)viewDidLoad {

[super viewDidLoad];

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

self.view.tag=10;

[self.view addGestureRecognizer:tap];

}

-(void)tap:(UITapGestureRecognizer*) recognizer

{

UIView * view=recognizer.view;

NSLog(@"%ld",(long)view.tag);

}

下面的方法是区分不同手势绑定一个View

-(void)UIGestureRecognizer:(UIGestureRecognizer*) recognizer{

if([recognizer isKindOfClass:[UIPinchGestureRecognizer class]]){

}

else if([recognizer isKindOfClass:[UITapGestureRecognizer class]] ){

}else{

}}
