在Mkannotation图像上添加Labeltext [英] Add Labeltext on Mkannotation image

问题描述

我正在使用带有自定义placeMark的MKMapView，它具有NSString值，我想将其作为标签添加到mkannotationview图像中.

I am using a MKMapView with custom placeMark, it has a NSString value and i'll like to add it as label to the mkannotationview image.

- (MKAnnotationView *)mapView:(MKMapView *)MapView viewForAnnotation:(MyPlaceMark *)annotation{

static NSString* AnnotationIdentifier = @"AnnotationIdentifier";

MKAnnotationView* MyView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier] autorelease];

MyView.canShowCallout=YES;
MyView.image = [UIImage imageNamed:@"MyImage.png"];
return MyView;}

哪一种是最好的获取方式，我试图在图像上添加标签，但是CGRect出现问题，却一无所获，不知道如何制作

Which would be the best way to get it, I tried to add a label to the image but I had problems with the CGRect and I get nothing, any idea how to make it

谢谢！

推荐答案

注释视图绘制图像?在这种情况下，我将添加UILabel作为子视图.

The annotation view draws the image? In that case I would add a UILabel as a subview.

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(x,y,width,height)];
[yourView addSubview:label];
[label release];
