iOS MKMapShapshotter completion block is not always being called

Question

I am trying to use the new iOS7 MKMapSnapshotter to generate a static map image. Whenever my app needs a map, I call the following:

MKMapSnapshotter *snapsho         


        

Answer 1

This issue is probably arising since snapshotter is not a property, therefore it is getting autoreleased soon after leaving this scope. Retaining snapshotter as a property should fix it.
