I have a map custom view that inherit from MKOverlayPathView. I need this custom view to display circle, line and text. I already managed to draw circle and line using path drawing CGPathAddArc and CGPathAddLineToPoint functions. However, I still need to add text. I tried to add text using [text drawAtPoint:centerPoint withFont:font]; but I got invalid context error. any idea? With MKOverlayPathView , I think the easiest way to add text is to override drawMapRect:zoomScale:inContext: and put the path and text drawing there (and do nothing in or don't implement createPath ). But if you're going

I am trying to capture tap event on my MKMapView , this way I can drop a MKPinAnnotation on the point where user tapped. Basically I have a map overlayed with MKOverlayViews (an overlay showing a building) and I would like to give user more information about that Overlay when they tap on it by dropping a MKPinAnnotaion and showing more information in the callout. Thank you. You can use a UIGestureRecognizer to detect touches on the map view. Instead of a single tap, however, I would suggest looking for a double tap ( UITapGestureRecognizer ) or a long press ( UILongPressGestureRecognizer ). A

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 this ), but the text does not appear. The circles show up correctly. (Also tried the first response's solution, same result). -(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

(Using iOS 5 and Xcode 4.2) I have an MKMapView and want to draw a circle of 1000m radius around the user location. On the surface it would seem that implementing the mapView:viewForAnnotation: map view delegate method, and adding a custom MKAnnotationView for the users location, would be a perfect solution. It would look something like this: - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { // If it's the user location, return my custom MKAnnotationView. if ([annotation isKindOfClass:[MKUserLocation class]]) { return myCustomAnnotationView; }

I am trying to display an animated gif in an overlay for MKMapView . The overlay is created using the MKOverlayRenderer . To animate the gif in iOS 7, I'm using the UIImage+animatedGIF category posted here on GitHub. The image of the animated gif displays fine in the overlay using the category; however, the gif does not animate. I have no problem using the category to animate a gif in a UIImageView but it does not seem to work correctly in a map view overlay. How can I use this category to place an animated gif in a map view overlay? or... Is there a way to place a UIImageView in the overlay
