title: Draw text in circle overlay
body: <p>I'm trying to draw some circle overlays containing text on MKMapView.
  I have subclassed the MKCircleView, in which I put the following (based on <a href="https://stackoverflow.com/questions/4165842/draw-simple-text-in-a-mkpolygonview">this</a>), but the text does not appear. The circles show up correctly. (Also tried the first response's solution, same result).</p>
  
  <pre><code>-(void)drawMapRect:(MKMapRect)mapRect zoomScale:(MKZoomScale)zoomScale inContext:(CGContextRef)context {
     [super drawMapRect:mapRect zoomScale:zoomScale inContext:context];
     NSString * t= @"XXXXX\nXXXX" ;
     UIGraphicsPushContext(context);
     CGContextSaveGState(context); 
     [[UIColor redColor] set];
     CGRect overallCGRect = [self rectForMapRect:[self.overlay boundingMapRect]];
     NSLog(@"MKC :  %lf, %lf ----&gt; %lf , %lf ", mapRect.origin.x ,mapRect.origin.y , overallCGRect.origin.x, overallCGRect.origin.y);
     [t drawInRect:overallCGRect withFont:[UIFont fontWithName:@"Arial" size:10.0] lineBreakMode:UILineBreakModeClip alignment:UITextAlignmentCenter];
     CGContextRestoreGState(context);
     UIGraphicsPopContext();
  }
  </code></pre>
  
  <p>When debugging, I get values like these</p>
  
  <pre><code>MKC :  43253760.000000, 104071168.000000 ----&gt; 1.776503 , 1.999245 
  MKC :  43253760.000000, 104071168.000000 ----&gt; -1.562442 , -2.043090
  </code></pre>
  
  <p>Are they normal ? What am I missing ? </p>
  
  <p>Thanks.</p>
