Question

我正在创建一个应用程序，它既可以是纵向也可以是横向模式。对于iOS 5.0，我按照以下方式添加视图，即

 -(BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation

{
   if(((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) ||
    (interfaceOrientation == UIInterfaceOrientationLandscapeRight)))
{
    productname.frame=CGRectMake(240, 97, 106, 20);
            self.view = landscapeView;

}

else if

(((interfaceOrientation == UIInterfaceOrientationPortrait) ||
          (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))){
    productname.frame=CGRectMake(153, 151, 106, 20);

    self.view = portraitView;

}

   return YES;

}

但对于iOS 6.0，我有两种方法，

（NSUInteger）supportedInterfaceOrientations
（BOOL）shouldAutorotate

我实际上需要一种必须在设备旋转期间触发的方法。如果有人有想法，请告诉我。我已经浪费了很多时间。

提前多多感谢。

Answer 1

我正在使用UINavigationController子类，代码如下：

    - (BOOL)shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    if (self.topViewController.presentedViewController) {
        return self.topViewController.presentedViewController.supportedInterfaceOrientations;
    }
    return self.topViewController.supportedInterfaceOrientations;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return self.topViewController.preferredInterfaceOrientationForPresentation;
}

这对我来说非常适合

并在AppDelegate.m文件中：

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return [UIDevice isIpad] ? UIInterfaceOrientationMaskAll : UIInterfaceOrientationMaskAllButUpsideDown;
}

Answer 2

使用

-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration

iOS 6.0轮换中的问题
