Adding an accessory view button to the MKMapView call out annotation?
提问by ingh.am
I've recently come across this websiteand I've been trying to add to my call out view a button (from a image).
我最近访问了这个网站，我一直试图在我的呼叫视图中添加一个按钮（来自图像）。
The code on the websites example works just fine, but when I tried to add in the same code to my project I'm not getting the same results.
网站示例中的代码运行良好，但是当我尝试将相同的代码添加到我的项目时，却没有得到相同的结果。
There is obviously something I've missed but I cannot seem to work this one out!
显然我错过了一些东西，但我似乎无法解决这个问题！
Here is my code for annotating:
这是我的注释代码：
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"];
annView.pinColor = MKPinAnnotationColorGreen;
UIButton *advertButton = [UIButton buttonWithType:UIButtonTypeCustom];
advertButton.frame = CGRectMake(0, 0, 23, 23);
advertButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
advertButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
[advertButton setImage:[UIImage imageNamed:@"button_right.png"] forState:UIControlStateNormal];
[advertButton addTarget:self action:@selector(showLinks:) forControlEvents:UIControlEventTouchUpInside];
annView.rightCalloutAccessoryView = advertButton;
annView.animatesDrop=TRUE;
annView.canShowCallout = YES;
annView.calloutOffset = CGPointMake(-5, 5);
return annView;
}
Any help would be appreciated! :)
任何帮助，将不胜感激！:)

Sorry to answer my own question but this was solved by setting the delegate of the MKMapView to the ViewController. Phew, took me a while to figure that out and it's so simple!!
很抱歉回答我自己的问题，但这已通过将 MKMapView 的委托设置为 ViewController 来解决。呼，我花了一段时间才弄明白，这太简单了！！

That guy is using a custom image to imitate the detail disclosure. You can actually get the standard detail disclosure quite easily:
那家伙正在使用自定义图像来模仿细节披露。您实际上可以很容易地获得标准的详细信息披露：
[UIButton buttonWithType:UIButtonTypeDetailDisclosure];

Instead of setting the target like you did here:
而不是像你在这里做的那样设置目标：
[advertButton addTarget:self action:@selector(showLinks:) forControlEvents:UIControlEventTouchUpInside];
You can use the default delegate:
您可以使用默认委托：
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
