iOS 给手势添加tag

在iOS 中 手势并没有像控件那样有tag值，但是有UIView属性，我们可以通过给UIView添加tag从而达到标记手势的效果。

下面请看代码：

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

[btnView addGestureRecognizer:tapGR];

UIView *singleTapView = [tapGR
view];

singleTapView.tag = i +
500;

- (void)clickMenuBtn:(id)sender

{

UITapGestureRecognizer *singleTap = (UITapGestureRecognizer *)sender;

NSLog(@"%ld",[singleTap
view].tag);

}
