UITapGeatureRecogniser无法处理2个标签

Question

我想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];
 }

Answer 1

默认情况下，禁用标签和图像视图的用户交互

启用它。

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

Answer 2

您需要启用标签的用户互动，例如：

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