ios - 如何从 AddressBook 中获取联系人并将其存储在 iOS 7 中的数组中？

Question

我正在尝试从地址簿中获取联系人，然后将其存储在数组中。我无法执行此操作。我检查了有关堆栈溢出的各种帖子，我正在编写相同的代码但无法执行？

CFErrorRef error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);
if (addressBook != nil) {
    NSLog(@"Succesful.");
    allContacts = (__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
    NSLog(@"allContacts.count = %d",[allContacts count]);}    allContact count is always zero

@property (nonatomic, assign) ABAddressBookRef addressBook;

//检查用户权限

 -(void)requestAddressBookAccess
{
    ViewController * __weak weakSelf = self;

    ABAddressBookRequestAccessWithCompletion(self.addressBook, ^(bool granted, CFErrorRef error)
                                             {
                                                 if (granted)
                                                 {
                                                     dispatch_async(dispatch_get_main_queue(), ^{
                                                         [weakSelf accessGrantedForAddressBook];

                                                     });
                                                 }
                                                 else{
                                                 }
                                             });
}

//获取所有联系方式

 -(void)accessGrantedForAddressBook{
    ABAddressBookRef addressBook = ABAddressBookCreate();
    CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
    CFMutableArrayRef peopleMutable = CFArrayCreateMutableCopy(
                                                               kCFAllocatorDefault,
                                                               CFArrayGetCount(people),
                                                               people
                                                               );
    NSMutableArray *allNames = (__bridge NSMutableArray*)peopleMutable;
}
