ABPeoplePickerNavigationController中的Objective-C - Locking旋转

Question

我的应用程序只使用肖像模式。但是ABPeoplePickerNavigationController支持景观。有没有可能让ABPeoplePickerNavigationController只支持纵向模式？

Answer 1

将其子类化并覆盖shouldAutorotateToInterfaceOrientation:

// .h file
@interface MMABPeoplePickerPortraitOnlyNavigationController : ABPeoplePickerNavigationController
@end

// .m file
@implementation MMABPeoplePickerPortraitOnlyNavigationController

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}

@end
