iOS7中读取通讯录信息授权问题

大家知道在读取通讯录信息时需要引用AddressBook、AddressBookUI得框架，然后就可以进行相关操作。但是在iOS7中不能够像iOS6中直接读取通讯录信息，而是需要代码中取得用户授权才可以进行相关操作。

推荐使用如下方式：

CFErrorRef *error = nil;                ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);            __block BOOL accessGranted = NO;        if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6            dispatch_semaphore_t sema = dispatch_semaphore_create(0);            ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {                accessGranted = granted;                dispatch_semaphore_signal(sema);        });            dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);            }        else { // we're on iOS 5 or older           accessGranted = YES;       }

 if (accessGranted) {
        
    NSMutableArray *addressBookTemp = [NSMutableArray array];
    //ABAddressBookRef addressBooks = ABAddressBookCreate();
    CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
    CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);
    
    
    for (NSInteger i = 0; i < nPeople; i++)
    {
        TKAddressBook *addressBook = [[TKAddressBook alloc] init];
        ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);
        CFStringRef abName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
        CFStringRef abLastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
        CFStringRef abFullName = ABRecordCopyCompositeName(person);
     } 
     ...................................
  }

另外，网上还有一种版本

//    CFErrorRef *error = nil;//    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);//    //    __block BOOL accessGranted = NO;//    //    if (ABAddressBookGetAuthorizationStatus()==kABAuthorizationStatusNotDetermined){//        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {//            //            accessGranted=granted;//        });//        //    }//    else if (ABAddressBookGetAuthorizationStatus()==kABAuthorizationStatusAuthorized){//        accessGranted=YES;//    }//    else//    {//        NSLog(@"用户未授权提示");//    }

不推荐后者得原因是：经过测试（模拟器）后者取得用户授权后并不能立刻执行获取联系人等得相关操作，而前者可以顺利执行。
