Crash when loading MKMapView

Question

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

Answer 1

Well, there is also a bit more simple solution to this. The actual problem is in using ABPeoplePickerNavigationController as a singleton object, setting its delegate to a view controller and then dismissing the view controller. So, in my case the solution that worked is this one:

• (void)peoplePickerNavigationControllerDidCancel: (ABPeoplePickerNavigationController *)peoplePicker { peoplePicker.peoplePickerDelegate = nil; // clear delegate prior to dismissing self [self.navigationController dismissViewControllerAnimated:YES completion:nil]; }

• (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { [self displayPerson:person]; peoplePicker.peoplePickerDelegate = nil; // clear delegate prior to dismissing self [self.navigationController dismissViewControllerAnimated:YES completion:nil]; return NO; }
