How do you access the current user's record in Address Book?

阅读更多关于 How do you access the current user's record in Address Book?

Is there a way in the Address Book API to access the current user's record programatically? In other words, if this iPhone belongs to John Smith, to get the contact record that is John Smith (whichever record is marked as Me in Contacts)? Obviously you can popup the picker and let the user select themselves from their Contacts, but this seems like an unnecessary action for the user to take. Use case: I have a form in my app and I'd like to pre-populate the form for the user based on their contact info they've already entered. It would be nicer to just display this for them than make them go

阅读更多关于 What are the Tags Around Default iPhone Address Book People Phone Number Labels?

My question concerns markup that surrounds some of the default phone number labels in the Person entries of the Contact list on the iPhone.

I wrote the following method to retrieve and display the labels

The following code does not work, but it seemed to be plausible: ABAddressBookRef addressBook = ABAddressBookCreate(); ABRecordRef delete = ABPersonCreate(); ABRecordSetValue(delete, kABPersonFirstNameProperty, @"Max", nil); ABRecordSetValue(delete, kABPersonLastNameProperty,

Why would ABAddressbookRef need to be created for each thread?

阅读更多关于 Why would ABAddressbookRef need to be created for each thread?

Apple says: Important: Instances of ABAddressBookRef can not be used by multiple threads. Each thread must make its own instance. But why? I know that some particular class or operations must be done in main thread. And I know some objects are not thread-safe (which means it would cause problem if these objects are accessed by two different threads concurrently). But, if you can make sure that the the thread-unsafe objects are accessed by only one thread at any moment, then there should be no problem. Do I understand correctly thus far? What I can't understand is, Why would some objects like

iOS Getting selected contacts' email address in array

阅读更多关于 iOS Getting selected contacts' email address in array

What I'm trying to do is show the people picker to the user, make him select all the contacts he wants, and finally get all those contacts' email addresses in an array. The best would be showing only contacts with email to the user. Until now the only thing I've been able to do is presenting the people picker with this code: ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; [self presentModalViewController:picker animated:YES]; Then I was trying to use this code to get the selected contacts' email: - (BOOL
