objective-c - Objective-C - 在 ABPeoplePickerNavigationController 中锁定旋转

Question

我的应用仅使用纵向模式。但是 ABPeoplePickerNavigationController 支持横向。是否可以让 ABPeoplePickerNavigationController 仅支持纵向模式？

Answer 1

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
