iOS通过手势拿到当前的View

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

- (void)tapAction:(id)sender{

    UITapGestureRecognizer *tap = (UITapGestureRecognizer *)sender;
    UIView *view = tap.view;
    NSInteger num = view.tag;
    if (_delegate && [_delegate respondsToSelector:@selector(imgClickWtinTag:) ]) {

        [_delegate imgClickWtinTag:num];
    }
}
