Question

我的应用程序中的tableView中有一个地址簿数据。此代码在模拟器中成功运行。我在模拟器中获取了我的应用程序的tableView中的联系人数据，但是当我在我的设备中测试它时，联系人的数据没有得到。我使用6.1模拟器和iPhone设备ios 6.1.3。请告诉我这段代码中的实际问题是什么？此代码在模拟器中成功运行，但它的代码未在iPhone设备iOS 6.1.3中运行

谢谢你

从IOS 6.它需要授权您的应用访问系统数据：在保密性标签和联系人部分的IPhone设置中，验证您的应用是否已访问

Answer 2

要继续TDelepine的建议，可能在您的getPersonOutOfAddressBook方法中，您可以检查您的应用是否具有AddressBook访问权限。如果尚未确定访问状态，下面的代码将强制设备要求用户访问：

 ...
NSLog(@"Succesful.");

if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {

       if(granted) {
            NSArray *allContacts = (__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
            etc...
        }
    });
}

我认为您没有发送访问地址簿的请求。另一件事如果您没有使用它，那么它在模拟器中正常工作但在iPhone中无法正常工作

在ViewDidLoad中使用此代码

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

if (accessGranted) {
    // Do whatever you want here.
}

获取地址簿数据它的代码在模拟器上运行，但没有运行iPhone设备。
