Implementation method of IOS address book information reading compatibility
There is a function in the project that requires reading the phone of the contact person in the address book. It was used before iOS8, and the following three proxy methods are mainly used to implement it
- (void) peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
- (BOOL) peoplePickerNavigationController:(ABPeoplePickerNavigationController *) peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
return NO;
}
But after the iOS8 update, a tragic thing happened:
// Deprecated, use predicateForSelectionOfPerson and/or -peoplePickerNavigationController:didSelectPerson: instead. - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person NS_DEPRECATED_IOS(2_0, 8_0); // Deprecated, use predicateForSelectionOfProperty and/or -peoplePickerNavigationController:didSelectPerson:property:identifier: instead. - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NS_DEPRECATED_IOS(2_0, 8_0);
Two of these methods were killed (this is too common for iOS developers)
Referring to the documentation, you can use the following two methods instead:
// Called after a person has been selected by the user. - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person NS_AVAILABLE_IOS(8_0); // Called after a property has been selected by the user. - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NS_AVAILABLE_IOS(8_0);
These two methods are like this, because the structure of the address book has changed after iOS8: the first layer is the name list, and after clicking on a certain person's name, is the detailed information of the person.
in:
The first method is to select this person and call it.
The second method is to select the details of this person and call it.
The code that parses specific information can be completely unchanged
