自定义MKAnnotationView按钮不可单击

Question

我正在使用MapQuest，但我认为这不是问题。

我有地图（使用MapQuest）和自定义引脚。我可以点击引脚和我的自定义标注（带标签和一个按钮的xib文件）弹出，一切正常。唯一的问题是我无法按下自定义标注视图（UIView）上的按钮。

这是我的代码：

-(MQAnnotationView*)mapView:(MQMapView *)aMapView viewForAnnotation:(id<MQAnnotation>)annotation {

    static NSString* identifier = @"Pins";
    MQAnnotationView * annotationView = (MQAnnotationView *)[self->mapView dequeueReusableAnnotationViewWithIdentifier:identifier];

    annotationView = [[MQAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
    annotationView.image = [UIImage imageNamed:@"marker_schuhe"];

    annotationView.enabled = YES;
    annotationView.canShowCallout = NO;

    return annotationView;
}

在我的didSelectAnnotationView方法中：

- (void)mapView:(MQMapView *)mapView didSelectAnnotationView:(MQAnnotationView *)view {
        callOutView *calloutView = (callOutView *)[[[NSBundle mainBundle] loadNibNamed:@"callOutView" owner:self options:nil] objectAtIndex:0];
    CGRect calloutViewFrame = calloutView.frame;
    calloutViewFrame.origin = CGPointMake(-calloutViewFrame.size.width/2 + 15, -calloutViewFrame.size.height);
    calloutView.frame = calloutViewFrame;

   [calloutView.my_button addTarget:self action:@selector(button_pressed:) forControlEvents:UIControlEventTouchUpInside]; //here is something wrong, button_pressed is never called

[view addSubview:calloutView];
}

Answer 1

在calloutView上设置userInteractionEnabled = YES;？

如果@selector无效（因为MKAnotationView拦截它），请尝试向UIGesture添加UIButton，如下所示：

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] 
            initWithTarget:self action:@selector(button_pressed:)];
        tap.numberOfTapsRequired = 1;
        [calloutView.my_button addGestureRecognizer:tap];
