iOS Mapkit自定义标注

问题描述

这是一个示例自定义标注，我希望得到类似的风格。我正在考虑从MKAnnotation继承，但我失去了如何启动它，我不知道标注的设计是否可以被覆盖。

如何使用ui控件实现这个自定义标注？

编辑：这是我的代码，来自类似的StackOverflow答案：

   - （MKAnnotationView *） mapView：（MKMapView *）mapview viewForAnnotation：（id< MKAnnotation>）注释
 {
 if（[annotation isKindOfClass：[MKUserLocation class]]）
 return nil; 
 static NSString * AnnotationIdentifier = @AnnotationIdentifier; 
 MKAnnotationView * annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier：AnnotationIdentifier]; 
 if（annotationView）
返回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; 
 
 / * 
 //用图像更改左侧附件视图按钮
 UIImageView * leftAccView = [[UIImageView alloc] initWithImage：img]; 
 annotationView.leftCalloutAccessoryView = leftAccView; 
 
 //包括一个显示更多信息的右键
 UIButton * rightButton = [UIButton buttonWithType：UIButtonTypeDetailDisclosure]; 
 [rightButton addTarget：self action：@selector（calloutSubMenu :) forControlEvents：UIControlEventTouchUpInside]; 
 [rightButton setTitle：annotation.title forState：UIControlStateNormal]; 
 annotationView.rightCalloutAccessoryView = rightButton; 
 * / 
 
返回annotationView; 
} 
返回零; 
} 
 
 //自定义附件视图
  - （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 allowedArrowDirections：UIPopoverArrowDirectionAny animated：YES]; 
} 
  

 （void）mapView：（MKMapView *）mapview annotationView：（MKAnnotationView *）view calloutAccessoryControlTapped：（UIControl *）control 
   
 
 
？但是会发生一个空白的常规标注。我可能做错了什么？
 
 
 
 BTW：UIViewController子类只在它的XIB上有一个标签，并且几乎是空白的。
解决方案
在几分钟的午睡后找到答案。
 
 
 
使用作为指南，我只需要覆盖
   - （void）mapView：（MKMapView *）mapView didSelectAnnotationView：（MKAnnotationView *）view 
  
显示注释标注。再次感谢安娜女士的回答。
 
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. 
Any ideas how to implement this custom callout with ui controls inside?
EDIT: Here's my code from following the similar StackOverflow answer:
- (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 
(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?
BTW: the UIViewController subclass only has a label on it's XIB and is pretty much blank.
 解决方案 
Found out the answer after a few mins of nap.
using this as the guide, I just needed to override 
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
which shows the annotation callout. Thanks again for the answer, Ms. Anna.
