title: Map Annotation showCallout-iOS
body: <p>I have problem to show the annotation title as shown in the following images. First image denotes value very well; on the other hand, once value goes up to three digits then title shows three dots as shown in the second image. I would like to know how to fix this problem. Any idea would be more than welcome!. Thanks a lot in advance, appreciated! I have just put my code here for reference!</p>
  
  <pre><code>- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id &lt;MKAnnotation&gt;)annotation {
     MKAnnotationView *pinView=nil;
      if(![annotation isKindOfClass:[Annotation class]]) // Don't mess user location
          return nil;
  
      static NSString *defaultPinID = @"StandardIdentifier";
      pinView = (MKAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
      if (pinView == nil){
          pinView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID];
      }
  
      if ([annotation isKindOfClass:[Annotation class]]) {
          Annotation *a = (Annotation *)annotation;
  
          pinView.image = [ZSPinAnnotation pinAnnotationWithColor:a.color];
          pinView.annotation = a;
          pinView.enabled = YES;
          pinView.centerOffset=CGPointMake(6.5,-16);
          pinView.calloutOffset = CGPointMake(-11,0);
  
      }
  
      pinView.canShowCallout = YES;
      UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
      [rightButton setTitle:annotation.title forState:UIControlStateNormal];
      [pinView setRightCalloutAccessoryView:rightButton];
      pinView.leftCalloutAccessoryView = [[UIView alloc] init];
      pinView.leftCalloutAccessoryView=nil;
  
      return pinView;
    }
  </code></pre>
  
  <p>My showCallout title is updated in the following code:</p>
  
  <pre><code>NSNumber *attr2=[attr valueForKey:@"ozone_level"];
  annotation.title=[NSString stringWithFormat:@"Ozone Level:%@",[attr2 stringValue]];
  </code></pre>
