使用UITabBar在iOS 6中自动旋转单个UIViewController [英] Autorotate a single UIViewController in iOS 6 with UITabBar

问题描述

我有一个仅适用于纵向模式的应用，但是有一个可以显示视频的单一视图，所以我希望该视图也能在<$ c $中工作c>横向模式，但是在iOS 6中我无法弄清楚我是如何做到的，现在我有了这个：

I have an app that work only in Portrait Mode, but there is a singleView that can display video, so i want that view work also in the landscape mode, but in iOS 6 I can't figure out how I can do it, now I have this:

在AppDelegate中.mi有：

In AppDelegate.m i have:

self.window.rootViewController = myTabBar;

然后在项目摘要中：

我找到了在iOS 6中检测视图旋转我必须这样做：

and i found that in iOS 6 to detect the view rotation i have to do this:

- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}

// Tell the system It should autorotate
- (BOOL) shouldAutorotate {
return YES;
}

所以我只在我的 UIViewController中插入上面的代码我想在景观中使用，但不起作用，任何人都知道我该怎么做？我只是想在显示视频时自动旋转。

so i insert the code above only in my UIViewController that I want use also in landscape, but don't work, anyone knows how i can do it? i just want the autorotate when show video.

推荐答案

首先，您的目标设置应如下所示：

Firstly, your target settings should look like this:

在UITabBarController中：

In UITabBarController:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // You do not need this method if you are not supporting earlier iOS Versions
    return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

-(NSUInteger)supportedInterfaceOrientations
{
    if (self.selectedViewController) 
        return [self.selectedViewController supportedInterfaceOrientations];

    return UIInterfaceOrientationMaskPortrait;
}

-(BOOL)shouldAutorotate
{
    return YES;
}

在ViewController中：

Inside your ViewController:

a）如果你不想轮换：

a) if you dont want to rotate:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (BOOL)shouldAutorotate
{
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

b）如果你想旋转到横向：

b) if you want to rotate to landscape:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

修改：

其他解决方案是在AppDelegate中实现此方法：

Other solution is to implement this method inside AppDelegate:

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    NSUInteger orientations = UIInterfaceOrientationMaskAll;

    if (self.window.rootViewController) {
        UIViewController* presented = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
        orientations = [presented supportedInterfaceOrientations];
    }
    return orientations; 
}
