How to remove non numeric characters from phone number in objective-c?
This is my first attempt to make an ios app. I'm using people picker to ask the user for a phone number, but when it retrieves with the code below, my NSString *phone apears like (0) 111192222-2222. I'm from Brazil and here the correct mask for mobile phone numbers is (01111) 92222-2222 (the 9 is optional, some numbers have others don't). How to fix this mask? Or remove it entirely? - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier
