VectorKit crash reports with MKMapSnapshotter on iOS

ios ios7 mapkit mkmapsnapshotter

How repeatable is this? Is the device coming out of sleep mode? What is on the screen when the App goes into the background?

Within the ViewController you can try registering the NSNotification event, UIApplicationWillResignActiveNotification

When the App is going into the background, calling cancel on any MKMapSnapshotter

If that doesn't work, you could attempt more drastic measures, like hiding views, just to identify if they are related to the crash.

I had the same issue with frequent but random crashes ususally looking like:

VectorKit 0x10663fe9 -[VKTileProvider tileSource:didFetchTile:forKey:] + 105

I fixed it by removing this line:

this.mapSnapshotter.Cancel();

So I think Apple has a bug with the MKMapSnapshotter Cancel method.

Hope that's helpful
