iOS 给 label 添加点击事件

// 1. 创建一个点击事件，点击时触发labelClick方法    
UITapGestureRecognizer *labelTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClick)];    
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(100, 100, 200, 100)];  
  
// 2. 将点击事件添加到label上    
[label addGestureRecognizer:labelTapGestureRecognizer];    
label.userInteractionEnabled = YES; // 可以理解为设置label可被点击

// 3. 在此方法中设置点击label后要触发的操作
- (void)labelClick {
}
