最簡單，最直接的方法。。。

自定義一個　UIView

核心程式碼如下：

//改變標註圖片和自定義氣泡

-(BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id<BMKAnnotation>)annotation

{

BMKAnnotationView *annotationView=[[BMKAnnotationViewalloc]initWithAnnotation:annotationreuseIdentifier:@"myAnnotation"];

    annotationView.image

//自定義內容氣泡

   UIView *areaPaoView=[[UIViewalloc]initWithFrame:CGRectMake(0, 0, 200, 100)];

    areaPaoView.layer.cornerRadius=8;

    areaPaoView.layer.masksToBounds=YES;

    areaPaoView.layer.contents =(id)[UIImageimageNamed:@"pao.png"].CGImage;//這張圖片是做好的透明

//areaPaoView.backgroundColor=[UIColor whiteColor];

if ([annotation.titleisEqualToString:@"1"]) { //假設title的標題為1，那麼就把新增上這個自定義氣泡內容

                       UILabel * labelNo = [[UILabelalloc]initWithFrame:CGRectMake(10, 0, 200, 30)];

            labelNo.text =[NSStringstringWithFormat:@"站點編號:%@"];

            labelNo.textColor = [UIColorblackColor];

            labelNo.

            [areaPaoViewaddSubview:labelNo];

           UILabel * labelStationName = [[UILabelalloc]initWithFrame:CGRectMake(10, 20, 200, 30)];

            labelStationName.text = [NSStringstringWithFormat:@"站點名稱:崑山中學"];

            labelStationName.textColor = [UIColorblackColor];

            labelStationName.backgroundColor = [UIColorclearColor];

            [areaPaoViewaddSubview:labelStationName];

           UILabel * labelSumNum = [[UILabelalloc]initWithFrame:CGRectMake(10, 40, 200, 30)];

            labelSumNum.text = [NSStringstringWithFormat:@"總樁數:30"];

            labelSumNum.textColor = [UIColorblackColor];

            labelSumNum.backgroundColor = [UIColorclearColor];

            [areaPaoViewaddSubview:labelSumNum];

           UILabel * labelBicycleNum = [[UILabelalloc]initWithFrame:CGRectMake(10, 60, 200, 30)];

            labelBicycleNum.text = [NSStringstringWithFormat:@"可借車:20"];

            labelBicycleNum.textColor = [UIColorblackColor];

            labelBicycleNum.backgroundColor = [UIColorclearColor];

            [areaPaoViewaddSubview:labelBicycleNum];

    }    

BMKActionPaopaoView *paopao=[[BMKActionPaopaoViewalloc]initWithCustomView:areaPaoView];

    annotationView.paopaoView=paopao;

   return annotationView;

}
