objective-c - ABPeoplePickerNavigationController 自动关闭而不显示地址簿

Question

我正在使用 ABPeoplePickerNavigationController 由用户选择地址簿联系人。使用此代码隐藏按钮操作:

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];

picker.peoplePickerDelegate = self;
picker.view.frame=self.view.frame;
[self presentModalViewController:picker animated:YES];
[picker release];

当此代码运行时，它会将横向 UI 旋转为纵向，并最终关闭呈现此 ABPeoplePickerNavigationController 的 Controller 。

我只在 iOS 5、iPad 2 上遇到这个问题。它在 iOS 6 上运行良好。

Answer 1

我不相信 5.x 中这个选择器支持横向。但是，请尝试通过不同的 PresentationStyle 来完成。我相信它应该在景观中工作，即:

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
picker.modalPresentationStyle  = UIModalPresentationFormSheet;
[self presentModalViewController:picker animated:YES];
