MKOverlay View is blurred

context 1.0 1.0 CGContextSetAlpha context 1.0 get the overlay bounds MKMapRect theMapRect self.overlay boundingMapRect CGRect theRect self rectForMapRect theMapRect Draw image CGContextDrawImage context theRect image CGImageRelease image CGContextRestoreGState.. graphics mkmapview overlay cgimage share improve this question I've had a similar problem. The problem was that my boundingMapRect was defined incorrectly. The full image is rendered scaled down when the scale is small on a tile. Then the map is zoomed.. rendered scaled down when the scale is small on a tile. Then the map is zoomed and not all the image tiles are in the boundingMapRect tiles so they are not redrawn in the correct scale and the scaled down version is zoomed. At least that's what I think happens...

Restrict MKMapView scrolling

http://stackoverflow.com/questions/4119117/restrict-mkmapview-scrolling

map view to the overlay's bounds so you'd have to do it manually. First make sure your MKOverlay object implements the boundingMapRect property. That can then be used in the regionDidChangeAnimated delegate method to manually adjust the view as needed. Here's.. obtained from mapView.overlays array. BOOL mapContainsOverlay MKMapRectContainsRect mapView.visibleMapRect theOverlay.boundingMapRect if mapContainsOverlay The overlay is entirely inside the map view but adjust if user is zoomed out too much... double widthRatio..
