copied!<p>As mentioned, <code>mapViewDidFinishLoadingMap</code> is sometimes not called at all, especially if the map tiles are already cached, and sometimes it is called multiple times. </p> <p>I notice that when it is called multiple times at the last call all of the tiles are rendered. So I think you can get this to work if you set up a 2 second timer after the map starts changing. Disable interactions so that the map does not continue to change, and enable user interactions when the timer goes off. </p> <p>If <code>mapViewDidFinishLoadingMap</code> gets called reset the timer again for 2 seconds into the future. When the timer finally goes off, you should have a fully rendered map. </p> <p>You will want to consider the other callbacks such as <code>mapViewDidFailLoadingMap</code>. Also test this on a noisy connection, since 2 seconds may not be long enough if it takes a long time to fetch the tiles. </p> <pre><code>- (void)restartTimer { [self.finishLoadingTimer invalidate]; self.finishLoadingTimer = [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(mapLoadingIsFinished) userInfo:nil repeats:NO]; } - (void)mapLoadingIsFinished { self.finishLoadingTimer = nil; self.mapChanging = NO; self.view.userInteractionEnabled = YES; } - (void)mapViewDidFinishLoadingMap:(MKMapView *)mapView { if (self.mapChanging) { [self restartTimer]; } } - (void)startLookingForMapChange { assert(self.mapChanging == NO); if (self.mapChanging == NO) { self.mapChanging = YES; assert(self.finishLoadingTimer == nil); self.view.userInteractionEnabled = NO; [self restartTimer]; } } </code></pre>
