I am having a peculiar crash when loading MKMapView. The pattern of occurrence is when I open ABPeoplePickerNavigationController in one view, which in turn triggers
MKMapView
I have had the same problem.
It's a leak issue on the ABPeoplePickerNavigationController. You have to ensure it won't be deallocated.
I'm declaring it as a strong property to ensure it won't be deallocated and it works fine :)
