【问题描述】:
我在 viewDidLoad 方法中添加了一个视图
- (void)viewDidLoad
{
CGRect mapFrame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
//Setup the map view
mapView = [[MQMapView alloc] initWithFrame:mapFrame];
mapView.mapZoomLevel = 15;
mapView.delegate = self;
[self.view addSubview:mapView];
[self.view sendSubviewToBack:mapView];
}
在我的 viewForAnnotation 方法中,我定义了一个注解视图
-(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_icon"];
annotationView.userInteractionEnabled = YES;
annotationView.enabled = YES;
annotationView.canShowCallout = NO;
return annotationView;
}
当我点击图标时,会调用 didSelectAnnotationView
- (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;
//Button Action
[calloutView.button_in_xib addTarget:self action:@selector(button_pressed:) forControlEvents:UIControlEventTouchUpInside]; //the button is defined in storyboard (xib-file)
calloutView.userInteractionEnabled = YES;
[view addSubview:calloutView];
}
子视图 (UIView) 可见(在地图视图的顶部),但按钮不可点击,因为从未调用方法“button_pressed”。
我尝试在子视图上将“userInteractionEnabled”设置为“YES”,但没有成功。
【问题讨论】:
-
尝试将该按钮放在 UIView 中。
-
谢谢拉詹,我已经试过了。我还尝试将按钮作为子视图添加到 calloutView-subview。当我点击按钮或子视图时,在 mapView 上调用点击事件并且地图正在放大。
-
可以添加callOutView xib的图片吗?
