iOS 给label UIText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 {

}
