无法在iOS8的联系人列表中选择人

Question

我意识到这个问题已经被事先询问过了，但是在那些线程中没有提及。 许多人似乎都遇到了问题，因为委托是在viewDidLoad中设置的，但是正如您从下面看到的那样，这不是我设置我的地方。 “取消”操作确实起作用，因此委托起作用，但实际上不起作用。

协议声明：

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

实例变量的定义：

@property (strong, nonatomic) ABPeoplePickerNavigationController *picker;

从按钮点击开始的过程：

- (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];
}

选择方法从未调用过（已通过断点验证）。

- (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];
}

选择联系人的特定属性时，将调用peoplePickerNavigationController:didSelectPerson:property:identifier:委托方法。 如果您想知道何时选择联系人，请使用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];
}
