如何從iPhone地址

Question

獲取電子郵件地址和姓名我都試過，但它崩潰：

- (NSDictionary *)contacts { 

    NSMutableArray *result = [NSMutableArray array]; 
    ABAddressBookRef addressBook = ABAddressBookCreate(); 
    CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook); 

    CFRelease(addressBook); 

    NSArray *peopleArray = (NSArray *)people; 

    // Return if there are no contacts in the address book 
    if (peopleArray && peopleArray.count > 0) { 

     for (int i = 0; i <= peopleArray.count - 1; i++) { 

      ABRecordRef person = [peopleArray objectAtIndex:i]; 
      ABRecordID sourceID = ABRecordGetRecordID(person); 

      ABMutableMultiValueRef multiEmail = ABRecordCopyValue(person, kABPersonEmailProperty); 

      NSString *emailAddress = (NSString *) ABMultiValueCopyValueAtIndex(multiEmail, 0); //EXE BAD ACCESS 

      [emailAddress release]; 
      CFRelease(multiEmail); 

      NSLog(@"email address %@", emailAddress); 

      NSString *sourceId = [NSString stringWithFormat:@"%i", sourceID]; 

      NSLog(@"%@", sourceId); 
     } 
    } 

    if (peopleArray) CFRelease(people); 
    return [NSArray arrayWithArray:result]; 
}

儘量不要釋放addressBook，直到你做。我有一個similar problem，並解決了這個問題。
