ios - UILabel 问题的 UITapGesture 选择器

Question

我为 self.view 和 UILabel(mainView 的 subview )添加了 tapGesture，每个执行不同的选择器。

但是调用了唯一的主视图 tapGesture 而没有调用标签 taggesture。如何处理？

代码如下:

UITapGestureRecognizer  *tapGesForSelf = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapGesForSelf:)];
[self.view addGestureRecognizer:tapGesForSelf];


UITapGestureRecognizer *tapLblClick = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapGesForLbl:)];
[lbl addGestureRecognizer:tapLblClick];

对于两个选择器，只有一种方法称为 tapGesForSelf。这里lbl是self.view的子view。

Answer 1

试试这个

- (void)viewDidLoad {
    [super viewDidLoad];
    [_lbl setUserInteractionEnabled:YES];
    UITapGestureRecognizer  *tapGesForSelf = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapGesForSelf:)];
    [self.view addGestureRecognizer:tapGesForSelf];
    UITapGestureRecognizer *tapLblClick = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapGesForLbl:)];
    [_lbl addGestureRecognizer:tapLblClick];
    [tapGesForSelf requireGestureRecognizerToFail:tapLblClick];
}
- (void)tapGesForSelf:(UITapGestureRecognizer *)gesture
{
    NSLog(@"self");
}
- (void)tapGesForLbl:(UITapGestureRecognizer *)gesture
{
    NSLog(@"label");
}
