使用storyboard segue显示ABPeoplePickerNavigationController

我有一个新项目，我想在触摸按钮时显示人物选择器。

所以我有一个UIButton ，它与一个标识为showContacts的通用UIViewController进行showContacts 。 我将此ViewController的类设置为ABPeoplePickerNavigationController 。

现在在我的根ViewController中我有这个代码来初始化我的选择器：

 #pragma mark - Segues -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ if([segue.identifier isEqualToString:@"showContacts"]){ ABPeoplePickerNavigationController *ppnc = segue.destinationViewController; ppnc.peoplePickerDelegate = self; ppnc.addressBook = ABAddressBookCreate(); ppnc.displayedProperties = [NSArray arrayWithObject:[NSNumber numberWithInt:kABPersonPhoneProperty]]; } } 

虽然我已将测试联系人添加到我的模拟器地址簿中，但结果如下所示：

没有选择器http://sofzh.miximages.com/objective-c/jbwUQyLr36ChH.png

使用以下代码，这与我在prepareForSegue:方法中的操作非常相似，我设法通过IBAction显示一个选择器：

 - (IBAction)showPicker:(id)sender { ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; NSArray *displayedItems = [NSArray arrayWithObjects:[NSNumber numberWithInt:kABPersonPhoneProperty], [NSNumber numberWithInt:kABPersonEmailProperty], [NSNumber numberWithInt:kABPersonBirthdayProperty], nil]; picker.displayedProperties = displayedItems; // Show the picker [self presentModalViewController:picker animated:YES]; } 

结果：

我不清楚为什么人物选择器没有显示。

贝西的答案很棒。 但是使用旧方法代替使用故事板的代码更少：

 - (void)showPeoplePicker:(id)sender { ABPeoplePickerNavigationController* picker = [[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; picker.modalPresentationStyle = UIModalPresentationFullScreen; picker.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentViewController:picker animated:YES completion:^{ // animation to show view controller has completed. }]; }

奇怪的是我的建议我可以使用segues与视图控制器的指定初始化器吗？ 我也解决了这个问题。 因此，为ABPeoplePickerNavigationController创建代理ViewController可以解决问题，但它没有解释为什么内置选择器无法在故事板中使用：

这是我的包装类的代码：

 #import "PeoplePickerViewControllerWrapper.h" @implementation PeoplePickerViewControllerWrapper @synthesize ppvc = _ppvc; // This is the object I'm proxying (The proxyee so to speak) @synthesize delegate = _delegate; - (void)awakeFromNib { self.ppvc = [[ABPeoplePickerNavigationController alloc] init ]; self.ppvc.peoplePickerDelegate = self; self.ppvc.addressBook = ABAddressBookCreate(); self.ppvc.displayedProperties = [NSArray arrayWithObject:[NSNumber numberWithInt:kABPersonPhoneProperty]]; } #pragma mark - View lifecycle - (void)loadView { [super loadView]; [self.ppvc loadView]; } - (void)viewDidLoad { [super viewDidLoad]; [self.ppvc viewDidLoad]; } -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [self.ppvc viewWillAppear:animated]; } -(void)viewDidDisappear:(BOOL)animated{ [super viewDidDisappear:animated]; [self.ppvc viewDidDisappear:animated]; } -(UIView *)view{ return self.ppvc.view; } - (void)viewDidUnload { [super viewDidUnload]; [self.ppvc viewDidUnload]; }

正如马特所指出的那样，旧的方式还可以。 如果要使用storyboard，可以在自定义视图控制器中添加ABPeoplePickerNavigationController，如下所示：

 - (void)awakeFromNib { ABPeoplePickerNavigationController * peoplePicker = [[ABPeoplePickerNavigationController alloc] init]; peoplePicker.peoplePickerDelegate = self; // Display only a person's phone and address NSArray * displayedItems = [NSArray arrayWithObjects:[NSNumber numberWithInt:kABPersonAddressProperty], [NSNumber numberWithInt:kABPersonPhoneProperty], nil]; peoplePicker.displayedProperties = displayedItems; [self.view addSubview:peoplePicker.view]; [self addChildViewController:peoplePicker]; [peoplePicker didMoveToParentViewController:self]; }
