Question

我意识到这个问题已被提前询问，但这些线程中没有提到任何问题。很多人似乎都有这个问题，因为委托是在viewDidLoad中设置的，但是你可以从下面看到，这不是我设置的地方。 “取消”操作是否有效，因此委托可以工作但不能实际选择。

声明的协议：

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

定义了实例变量：

@property (strong, nonatomic) ABPeoplePickerNavigationController *picker;

通过按钮点击启动流程：

- (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];
}

从未调用选择方法（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];
}

选择联系人上的特定属性时，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];
}
