Question

当我旋转设备时我遇到了UIModalTransitionStylePartialCurl的问题，因为卷曲没有像我预期的那样旋转，我发现下面提取的答案，但我无法拒绝。

我不知道如何创建一个“rootviewcontroller”属性，如下所示

所以我正在寻找你的指导，继续前进。我很长时间都坚持这件事......

UIView Animation: PartialCurl ...bug during rotate?

我也有这个问题而且有点放弃了。但是，我提到了我的   朋友的困境，鼓励我调查孩子的VC   逻辑和我回忆起一个方便的技巧，我曾经用它来传递数据   父/子视图控制器。

在您的侧视图控制器中，创建一个“rootViewController”   属性。在父视图控制器中，初始化时   翻转视图控制器，你设置（其中“self”是rootVC）：
flipsideController.rootViewController = self;
然后你将它用于你的翻转VC   shouldAutorotateToInterfaceOrientation方法：

-   （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）interfaceOrientation   {return interfaceOrientation ==   self.rootViewController.interfaceOrientation;

}

中提琴！翻转视图不再在部分下方旋转   卷起父母的观点！

@From post：在您的侧视图控制器中，创建一个“rootViewController”属性。

#import <UIKit/UIKit.h>

@class ModalViewExampleViewController;

@interface flipSideViewController : UIViewController {

    ModalViewExampleViewController *rootViewController;

}
@property (nonatomic, retain) ModalViewExampleViewController *rootViewController;

@end

并在您的flipSideViewController的实现文件中

#import "ModalViewExampleViewController.h"

@synthesize rootViewController;
