地图sdk ios公开课lesson用于在上显示标记

iOSSDK了解自定义了解@brief关联的@property(nonatomic,strong)id<MAAnnotation>@brief显示的@property(nonatomic,strong)UIImage@brief默认情况下,annotationview的中心位于annotation的坐标位置，可以设置@property(nonatomic)CGPointf 默认情况下, 弹出的气泡位于正中上方，以设置改变的偏移使@property(nonatomic)CGPoint@interfaceMAPinAnnotationView:导入标 文-(MAAnnotationView*)mapView:(MAMapView*)mapView{if([annotationisKindOfClass:[MAPointAnnotation{staticNSString*reuseIndetifier=MAAnnotationView*annotationView=(MAAnnotationView*)[mapViewif(annotationView=={annotationView=[[MAAnnotationViewalloc]initWithAnnotation:annotation}annotationView.image=[UIImage//设置中心点偏移，使得标注底部中间点成为 annotationView.centerOffset=CGPointMake(0,-18);returnannotationView;}return}56@interfaceCustomCalloutView:@property(nonatomic,strong)UIImage*image;@property(nonatomic,copy)NSString*title;@property(nonatomic,copy)NSString*subtitle;
