已修复!这是完成工作的代码:
Fixed! This is the code that gets the job done:
-(void)drawMapRect:(MKMapRect)mapRect zoomScale:(MKZoomScale)zoomScale inContext:(CGContextRef)context
{
UIImage *image = [UIImage imageNamed:@"snowmap.png"];
MKMapRect theMapRect = [self.overlay boundingMapRect];
CGRect theRect = [self rectForMapRect:theMapRect];
UIGraphicsPushContext(context);
[image drawInRect:theRect blendMode:kCGBlendModeNormal alpha:1.0];
UIGraphicsPopContext();
}
