iOS 在父视图添加手势，点击子视图，会响应父视图的手势

- (void)viewDidLoad {
    [super viewDidLoad];
    
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                          action:@selector(click)];
    [self.view addGestureRecognizer:tap];
    
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    button.frame = CGRectMake(0, 0, 350, 400);
    button.backgroundColor = [UIColor redColor];
    [self.view addSubview:button];
    [button addTarget:self action:@selector(kkk) forControlEvents:UIControlEventTouchUpInside];
    [button setTitle:@"我是一个按钮" forState:UIControlStateNormal];
    button.titleLabel.font = [UIFont systemFontOfSize:80];
    button.titleLabel.numberOfLines = 0;
    
    
    UILabel *ve = [[UILabel alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
    ve.backgroundColor = [UIColor cyanColor];
    ve.text = @"我是label1";
    ve.userInteractionEnabled =  YES;
    [self.view addSubview:ve];
    
    UILabel *ve2 = [[UILabel alloc] initWithFrame:CGRectMake(100, 500, 100, 100)];
    ve2.backgroundColor = [UIColor magentaColor];
    ve2.text = @"我是label2";
    ve2.userInteractionEnabled = YES;
    [self.view addSubview:ve2];
    // Do any additional setup aft
    // Do any additional setup after loading the view.
}
