無法在iOS8的聯系人列表中選擇人

Question

我意識到這個問題已經被事先詢問過了，但是在那些線程中沒有提及。 許多人似乎都遇到了問題，因為委托是在viewDidLoad中設置的，但是正如您從下面看到的那樣，這不是我設置我的地方。 “取消”操作確實起作用，因此委托起作用，但實際上不起作用。

協議聲明：

@interface MyTrackDetailsTVC () <UITextFieldDelegate,UIImagePickerControllerDelegate,ABPeoplePickerNavigationControllerDelegate>

實例變量的定義：

@property (strong, nonatomic) ABPeoplePickerNavigationController *picker;

從按鈕點擊開始的過程：

- (IBAction)importContactTapped:(UIButton *)sender
{
    self.picker = [[ABPeoplePickerNavigationController alloc] init];

    self.picker.peoplePickerDelegate = self;

    [self presentViewController:self.picker animated:YES completion:nil];
}

取消方法效果很好：

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker

{
    [[peoplePicker presentingViewController]dismissViewControllerAnimated:YES completion:nil];
}

選擇方法從未調用過（已通過斷點驗證）。

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
    NSString *fName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSString *lName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
    NSData *imgData = (__bridge_transfer NSData *)ABPersonCopyImageData(person);

    self.nameField.text = [NSString stringWithFormat:@"(%@ %@",fName,lName];
    self.phoneField.text = lName;

    self.imageView.image = [UIImage imageWithData:imgData];

    [[peoplePicker presentingViewController]dismissViewControllerAnimated:YES completion:nil];
}

選擇聯系人的特定屬性時，將調用peoplePickerNavigationController:didSelectPerson:property:identifier:委托方法。 如果您想知道何時選擇聯系人，請使用peoplePickerNavigationController:didSelectPerson:委托方法。

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person
{
    NSString *fName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSString *lName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
    NSData *imgData = (__bridge_transfer NSData *)ABPersonCopyImageData(person);

    self.nameField.text = [NSString stringWithFormat:@"(%@ %@",fName,lName];
    self.phoneField.text = lName;

    self.imageView.image = [UIImage imageWithData:imgData];

    [[peoplePicker presentingViewController]dismissViewControllerAnimated:YES completion:nil];
}
