iOS Mapkit Custom Callout
提问by Bahamut
Here's a sample custom callout that I'd want to get a similar style of. I was thinking of inheriting from MKAnnotation but I'm lost how to start it and I don't know if the callout's design could be overridden.
这是我想要获得类似样式的示例自定义标注。我想从 MKAnnotation 继承，但我不知道如何启动它，我不知道标注的设计是否可以被覆盖。
Any ideas how to implement this custom callout with ui controls inside?
任何想法如何在内部的 ui 控件中实现此自定义标注？
EDIT: Here's my code from following the similar StackOverflow answer:
编辑：这是我遵循类似 StackOverflow 答案的代码：
- (MKAnnotationView *)mapView:(MKMapView *)mapview viewForAnnotation:(id <MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
static NSString* AnnotationIdentifier = @"AnnotationIdentifier";
MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier];
if(annotationView)
return annotationView;
else
{
UIImage *img = [UIImage imageNamed:@"default_thumb.png"];
MKAnnotationView *annotationView =
[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
annotationView.canShowCallout = YES;
annotationView.image = img;
annotationView.draggable = YES;
/*
// change left accessory view button with image
UIImageView *leftAccView = [[UIImageView alloc] initWithImage:img];
annotationView.leftCalloutAccessoryView = leftAccView;
//include a right button to show more info
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:@selector(calloutSubMenu:) forControlEvents:UIControlEventTouchUpInside];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
annotationView.rightCalloutAccessoryView = rightButton;
*/
return annotationView;
}
return nil;
}
// Customize accessory view
- (void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
[mapview deselectAnnotation:view.annotation animated:YES];
PopOverCallout *popOverCallout = [[PopOverCallout alloc]init];
UIPopoverController *popOver = [[UIPopoverController alloc] initWithContentViewController:popOverCallout];
self.annotationPopoverController = popOver;
popOver.popoverContentSize = CGSizeMake(500, 500);
[popOver presentPopoverFromRect:view.bounds inView:view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
The
这
(void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
should be called whenever the pin is touched to show the callout right? but what happens is that a blank regular callout is shown. What might I be doing wrong?
应该在触摸引脚时调用以显示标注吗？但会发生什么是显示一个空白的常规标注。我可能做错了什么？
BTW: the UIViewController subclass only has a label on it's XIB and is pretty much blank.
顺便说一句： UIViewController 子类的 XIB 上只有一个标签，而且几乎是空白的。

Found out the answer after a few mins of nap.
小睡几分钟后找到答案。
using thisas the guide, I just needed to override
使用此为指导，我只需要覆盖
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
which shows the annotation callout. Thanks again for the answer, Ms. Anna.
其中显示了注释标注。再次感谢您的回答，安娜女士。
