How do I make my MPMoviePlayerController Play in Landscape?
提问by jakife
I am trying to make my video from youtube play in landscape mode. I turned off landscape left and right for supported device orientation because if it was on, every view is able to go landscape. I'm building this for iOS 6. How do I make my video play in landscape.
我正在尝试以横向模式从 youtube 播放我的视频。我为支持的设备方向关闭了左右横向，因为如果它打开，每个视图都可以横向显示。我正在为 iOS 6 构建这个。如何让我的视频在横向播放。
Here is my code
这是我的代码
#import "VideoTViewController.h"
#import "HCYoutubeParser.h"
#import <MediaPlayer/MediaPlayer.h>
@interface VideoTViewController ()
@end
@implementation VideoTViewController
@synthesize tLabel;
-(IBAction)playVideo
{
NSDictionary *videos = [HCYoutubeParser h264videosWithYoutubeURL:[NSURL URLWithString:@"http://www.youtube.com/watch?v=zz_bJ58LfCg&feature=youtu.be"]];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:[videos objectForKey:@"medium"]]];
[self presentViewController:mp animated:YES completion:nil];
}
Edit:
编辑：
I did the following:
我做了以下事情：
Made a new class
做了一个新班级
AboutNavViewController (which subclasses a UiNavigationController)
AboutNavViewController（它是 UiNavigationController 的子类）
#import "AboutNavViewController.h"
@interface AboutNavViewController ()
@end
@implementation AboutNavViewController
- (BOOL)shouldAutorotate {
return NO;
}
- (BOOL)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
@end
And in my aboutviewcontroller (which subclasses a uiviewcontroller)
在我的 aboutviewcontroller（它是 uiviewcontroller 的子类）中
#import "AboutViewController.h"
#import "AboutNavViewController.h"
@interface AboutViewController ()
@end
@implementation AboutViewController
@synthesize aLabel;
- (void)viewDidLoad
{
[super viewDidLoad];
CGRect frame = CGRectMake(0, 0, 320, 44);
aLabel = [[UILabel alloc] initWithFrame:frame];
aLabel.backgroundColor = [UIColor clearColor];
[aLabel setFont:[UIFont fontWithName:@"SerifGothic LT Black" size:25]];
aLabel.text = @"Sephardi Jews";
aLabel.textAlignment = NSTextAlignmentCenter;
aLabel.textColor =[UIColor whiteColor];
self.navigationItem.titleView = aLabel;
AboutNavViewController *about = [[AboutNavViewController alloc] init];
[self presentViewController:about animated:YES completion:nil];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
@end
I get the following error:
我收到以下错误：
Unbalanced calls to begin/end appearance transitions for .
对 的开始/结束外观转换的不平衡调用。
What am I doing wrong?
我究竟做错了什么？

Note: You must add landscape left and right to your supported interface orientations in Info.plist for this to work.
注意：您必须在 Info.plist 中向支持的界面方向添加左右横向，才能使其正常工作。
The system determines whether an orientation is supported by intersecting the value returned by the app's supportedInterfaceOrientationsForWindow: method with the value returned by the supportedInterfaceOrientations method of the top-most full-screen controller.
系统通过将应用程序的 supportedInterfaceOrientationsForWindow: 方法返回的值与最顶层全屏控制器的 supportedInterfaceOrientations 方法返回的值相交来确定是否支持某个方向。
Added iOS 6 autorotation methods from previous answer"
从以前的答案中添加了 iOS 6 自动旋转方法”
@interface MyMovieViewController : MPMoviePlayerViewController
@end
@implementation MyMovieViewController
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
@end
