MapKit iPhone Development - Adding Annotations to a Map - iOS SDK
提问by Laurenz
I would like to create annotations on a Map like this:
我想在地图上创建这样的注释：
If you click on the blue arrow a menu should open. In the menu should be two menu points. First a Telephone number (if I click on the number the iphone dial/call this number) and second a "Directions to here".
如果您单击蓝色箭头，应打开一个菜单。在菜单中应该有两个菜单点。首先是电话号码（如果我点击该号码，iphone 会拨打/拨打此号码），然后是“到这里的路线”。
At the moment I run on this code
目前我在这段代码上运行
MKCoordinateRegion region4 = { {0.0, 0.0 }, { 0.0, 0.0 } };
region4.center.latitude = 48.13479 ;
region4.center.longitude = 11.582111;
region4.span.longitudeDelta = 0.01f;
region4.span.latitudeDelta = 0.01f;
DisplayMap *ann4 = [[DisplayMap alloc] init];
ann4.title = @"The Title!";
ann4.subtitle = @"The Subtitle!";
ann4.coordinate = region4.center;
[mapView addAnnotation:ann4];
How do I show blue-arrow as shown in the image? Can you please suggest me on this..

Check out the MKAnnotationView Class Reference, and "Managing Callout Views" specifically.
