点击标签时返回标签 [英] Return tag of the label when it it tapped

问题描述

我的视图中有5个标签，分别标记为1,2,3,4和5.我在其上启用了用户互动，并添加了一个点按手势。

I have 5 labels in my view, respectively tagged 1, 2, 3, 4 and 5. I have enabled user interaction on them, and added a tap gesture.

现在我想要的是获取标签的标签。

Now what I want is to get the tag of the label being touched.

我正在做这样的事情：

tapGesture=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGestureSelector)];

tapGesture.numberOfTapsRequired = 1.0;     

- (void)tapGestureSelector :(id)sender
{
    // I need the tag to perform different tasks.
    // So that I would like to get the touched label's tag here.    
}

如果我不清楚我的问题，请问我。

If I am not clear in my question please ask me.

感谢您的帮助。

I find the solution in this way and it worked for me very fine. I hope that it will also help you. It is very simple and short.

我们可以通过将此函数添加到.m文件中来获取标签的标记。

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch=[touches anyObject];
    UILabel *label=(UILabel *)touch.view;

    NSLog(@"Label that is tapped has tag %d",label.tag);
}
