App freezes / can no longer pan or zoom

[springmeyer]

This is freeze is not a crash. The display stays up and tiles might even continue to load around the edges. But all of the touch events are no longer recognized.

I can workaround but hitting the navigation button to zoom to the full extents of the map and then the touch events are again recognized.

It appears that it may be a kind of race condition with tile loading. I've triggered it when zooming out and rotating - I can see tiles around the borders are missing and when they start loading and displaying then the freeze happens.

Seeing this on an iPhone 5c (Model A1456, A1532) with iOS 7.1.1 (11D201) both in debug and release mode.

Yeah, going to look into this still. Relates to a forced un-rotate at low zooms that we don't want gestures to interrupt. Cases where this happens in MVKMapView.h:

if ( ! [self cancelPreviousActions]) return;

Need to touch that up / possibly remove.

I will hit this today. If I can't resolve, I will get rid of the nice, smooth auto-rotate-to-north-at-low-zooms that indirectly is causing this.

Finally tracked this down to deadlock problems with animated rotation followed by an unchecked notify_map_change() which needs to get lat, lon, and zoom. Fix almost in.

Ok, punting on this. Removing animations & moving to #296.
