【问题描述】：

我试图在两个标签上使用两个TapGestures，但它总是显示最后一个 TapGesture 的结果。我的代码如下：

 [write_review_label addGestureRecognizer:[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(open_view:)]];
[map_image addGestureRecognizer:[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(open_view:)]];
write_review_label.tag = 1;
map_image.tag = 2;

-(void)open_view:(UITapGestureRecognizer *)recog1

NSLog( @"recog1.view.tag == %d",recog1.view.tag);
if (recog1.view.tag==2)

    [self performSegueWithIdentifier:@"mapsegue" sender:self];

else
    [self performSegueWithIdentifier:@"loginsegue" sender:self];
 

【参考方案1】：

默认情况下，标签和图像视图的用户交互是禁用的，

启用它。

[write_review_label setUserInteractionEnabled:YES];   
[map_image setUserInteractionEnabled:YES];

【参考方案2】：

您需要启用标签的用户交互，例如：

write_review_label.userInteractionEnabled = YES;
map_image.userInteractionEnabled = YES;
