如何在ios 7中授予访问电话通讯簿的权限？

上述代码在模拟器中运行良好，但当我在iPhone5c中运行应用程序时，它并没有请求我的许可，而且我无法从设备地址簿中获取电话号码

帮我解决这个问题。

提前谢谢。

在您的

viewDidLoad

方法中调用此行

NSMutableArray *arrContacts=[[NSMutableArray alloc]init];


    CFErrorRef *error = nil;

    ABAddressBookRef addressbook = ABAddressBookCreateWithOptions(NULL, error);

    __block BOOL accessGranted = NO;

    if (ABAddressBookRequestAccessWithCompletion != NULL) { // we are used on the iOS 6
        dispatch_semaphore_t sema = dispatch_semaphore_create(0);
        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
            @autoreleasepool {
                // Write your code here...
                // Fetch data from SQLite DB
            }
        });

        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)
    {
