iOS 给label添加点击事件

iOS 给label添加点击事件

// 1. 建立一个点击事件，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; // 能够理解为设置label可被点击

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

}
