MPMoviePlayerViewController |允许横向模式 [英] MPMoviePlayerViewController | Allow landscape mode

问题描述

我正在尝试在我的应用中流式传输视频。我发现的方法是：

I'm trying to stream a video in my app. The method I've found is :

NSURL *theMovieURL = [NSURL URLWithString:self.data.trailer];
        if (theMovieURL)
        {
            self.movieController = [[MPMoviePlayerViewController alloc] initWithContentURL:theMovieURL];
            [self presentMoviePlayerViewControllerAnimated:self.movieController];
            [self.movieController.moviePlayer play];
        }

我不确定它是否是最传统的，但它确实有效。

I'm not sure if it's the most conventional, but it works.

问题是我无法弄清楚如何仅为视频设置横向模式。我应该使用像 shouldAutorotate 或 shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）toInterfaceOrientation ，以及如何使用？

The problem is that I can't figure out how to allow the landscape mode, for the video only. Should I use something like shouldAutorotate or shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation , and how ?

仅供参考，整个应用程序仅允许纵向模式。

FYI, the entire app allows only the portrait mode.

感谢您的帮助。

推荐答案

shouldAutoRotate 从iOS 6开始被弃用，除非你想要< 6。

shouldAutoRotate is deprecated as of iOS 6 and should be avoided unless you're going for < 6 .

相反，你想要覆盖 supportedInterfaceOrientations 和 preferredInterfaceOrientationForPresentation 方法。

Instead, you'd want to override the supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation methods.

在这种情况下，如果您不想为媒体播放器创建子类，则可以覆盖app委托中的方法，如下所示： / p>

In this case, if you don't want to subclass the media player you could override a method in the app delegate like so:

- (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if ([[self.window.rootViewController presentedViewController] isKindOfClass:[MPMoviePlayerViewController class]])
    {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }
    else
    {
        return UIInterfaceOrientationMaskPortrait;
    }
}
