ios - iOS8 无法从联系人列表中选择人员

Question

我意识到之前有人问过这个问题，但这些线程中没有提到任何内容。许多人似乎有这个问题，因为委托(delegate)是在 viewDidLoad 中设置的，但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，因此代表起作用但不用于实际选择。

声明的协议(protocol):

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

实例变量定义:

@property (strong, nonatomic) ABPeoplePickerNavigationController *picker;

从点击按钮开始的过程:

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

    self.picker.peoplePickerDelegate = self;

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

取消方法工作得很好:

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker

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

从未调用过选择方法(使用断点验证)。

- (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];
}

peoplePickerNavigationController:didSelectPerson:property:identifier: 委托(delegate)方法在选择联系人的特定属性时调用。如果您想知道联系人何时被选中，请使用 peoplePickerNavigationController:didSelectPerson: 委托(delegate)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];
}
