停止旋转模态UIViewController

Question

模态UIViewController的父级自动旋转,但是当模态VC启动时,我只希望它以纵向显示而不能旋转.我试过简单地从shouldAutorotate模态VC中返回NO ,但没有快乐.支持iOS 5+.

任何帮助非常感谢.

Answer 1

基本上,如果你在任何容器控制器(即UINavigationController)上呈现模态控制器,它具有自动旋转方法默认返回YES.因此,您必须为您的UINavigation Controller和Deprecate Autorotation创建子类.

对于iOS 5使用方法:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

    return (toInterfaceOrientation == UIInterfaceOrientationPortrait) : self.enableRotations;
}

对于iOS 6:

- (NSUInteger)supportedInterfaceOrientations {

    switch ([UIDevice currentDevice].userInterfaceIdiom) {

        case UIUserInterfaceIdiomPad:   return UIInterfaceOrientationMaskAll;
        case UIUserInterfaceIdiomPhone: return UIInterfaceOrientationMaskPortrait;
    }
}

- (BOOL)shouldAutorotate {

    return NO;
}
