ios6中的方向问题 [英] orientation issue in ios6

问题描述

我在我的应用程序中使用UINavigationController，我的第一个控制器名为 A ，只有portrite是严格的，我的 A 控制器中有一个按钮。我点击在按钮上，我正在为另一个名为 B 的视图控制器创建实例。在为BI创建实例后，使用以下方法进行模态显示

I am using UINavigationController in my application and my first controller called A and it is strict to portrite only and there is a button in my A controller.Once I click on the button I am creating instance to the another view controller called B. After creating the instance for B I am presenting modally using below method

[self presentViewController:BInstance animated:YES completion:^{
            NSLog(@"completed");
        }];

我的B控制器能够支持所有方向，这是预期的，直到ios5.1和早期版本。现在我正在尝试使用Xcode4.5在ios6上运行我的项目它没有被轮换我期待解决这个问题我发现一些关于 shouldAutorotateToInterfaceOrientation：方法的博客从最新版本中被弃用了iOS6的。我也使用了替代方案

My B controller can able will support all the orientations, this is expected, till the ios5.1 and earlier versions. Now I am trying to run my project on the ios6 using Xcode4.5 it is not getting rotated I am looking forward to solve the issue I found some of the blogs about shouldAutorotateToInterfaceOrientation: method got deprecated from the latest ios6. I used alternative also

-(BOOL)shouldAutorotate{
    return YES;
}
-(NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskAll;
}

但预期结果仍然不多。

问题：即使我的父 A 仅适用于portrite，我的 B 控制器将适用于所有方向。

Question: What makes my B controller will work for all orientations even my Parent A works only for portrite.

在此先感谢您对此有用的所有建议/建议。

推荐答案

首先，在AppDelegate中，写下这个。 这非常重要

First of all, in AppDelegate, write this. THIS IS VERY IMP

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
     return (UIInterfaceOrientationMaskAll);
}

然后，对于UIViewControllers，你只需要 PORTRAIT 模式，写下这些函数

Then, For UIViewControllers, in which you need only PORTRAIT mode, write these functions

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return (UIInterfaceOrientationMaskPortrait);
}

对于需要 LANDSCAPE 的UIViewControllers，请更改屏蔽全部。

For UIViewControllers, which require LANDSCAPE too, change masking to All.

- (NSUInteger)supportedInterfaceOrientations
{
    return (UIInterfaceOrientationMaskAllButUpsideDown);
    //OR return (UIInterfaceOrientationMaskAll);
}

现在，如果你想在Orientation改变时做一些改变，那么使用这个函数。

Now, if you want to do some changes when Orientation changes, then use this function.

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{

}
