Ios 从纵向视频到横向视频

我知道像这样的问题可能已经存在了，但为了像我这样的人，我会继续问下去

我有一个应用程序，设置为只允许纵向，但此设置会影响我的视频，因为我希望只有视频能够在横向播放。是否有一种方法可以添加到.m文件中以使其正常工作？这是我的密码

 #import "BIDVideosViewController.h"

 @interface BIDVideosViewController ()

 @implementation BIDVideosViewController

 @synthesize moviePlayer ;


 @synthesize tableList;


 - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
 {
 self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
 if (self) {
    // Custom initialization
 }
 return self;
 }

 {
 [super viewDidLoad];
 UITableView *table = [[UITableView alloc]initWithFrame:self.view.bounds];
 [table setDelegate:self];
 [table setDataSource:self];
 [self.view addSubview:table];
 tableList = [[NSMutableArray alloc] initWithObjects:@"Gangan",@"SwimGood",@"German Ice", nil];

 }

 return [tableList count];
 }

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:DisclosureButtonIdentifier];
 if (cell == nil)
 {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:DisclosureButtonIdentifier];
 }

 NSInteger row = [indexPath row];
 NSString *rowString = [tableList objectAtIndex:row];
 cell.textLabel.text = rowString;

 return cell;
 }

    NSBundle *str = [tableList objectAtIndex:indexPath.row];
    if ([str isEqual:@"Gangan"])
    {

        NSString *thePath = [bundle pathForResource:@"Gangan" ofType:@"mp4"];
        NSURL *theurl = [NSURL fileURLWithPath:thePath];
        moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theurl];

        [moviePlayer setMovieSourceType:MPMovieSourceTypeFile];
        [self.view addSubview:moviePlayer.view];
        [moviePlayer setFullscreen:YES];

        [moviePlayer play];
    }
    else if ([str isEqual:@"SwimGood"])
    {
        NSBundle *bundle = [NSBundle mainBundle];
        NSString *thePath = [bundle pathForResource:@"SwimGood" ofType:@"mp4"];
        NSURL *theurl = [NSURL fileURLWithPath:thePath];
        moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theurl];
        [moviePlayer setMovieSourceType:MPMovieSourceTypeFile];
        [self.view addSubview:moviePlayer.view];
        [moviePlayer setFullscreen:YES];

        [moviePlayer play];

    }
    else if ([str isEqual:@"German Ice"])
    {
        NSBundle *bundle = [NSBundle mainBundle];
        NSString *thePath = [bundle pathForResource:@"German Ice" ofType:@"mp4"];
        NSURL *theurl = [NSURL fileURLWithPath:thePath];
        moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theurl];
        [moviePlayer setMovieSourceType:MPMovieSourceTypeFile];
        [self.view addSubview:moviePlayer.view];
        [moviePlayer setFullscreen:YES];

        [moviePlayer play];
    }

   }
   }

在视图控制器.m文件中，您应该

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

对于支持的方向，您可以返回

YES

，这将使您能够旋转视频

另外，如果使用UINavigationController，此方法也不会起作用，除非

UINavigationController

implement

-（BOOL）管理的所有视图都应该以相同的方式进行AutoRotateTointerFaceOrientation:（UIInterfaceOrientation）interfaceOrientation

此外，在目标->项目->摘要中，您可以设置支持的方向

编辑： 去寻找UIInterfaceOrientation。这里有你需要的常数

我会这样写：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    if (interfaceOrientation == UIInterfaceOrientationPortrait)
       return YES;  
    if (interfaceOrientation == UIInterfaceOrientationLandscapeRight)
       return YES; 
    if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
       return YES;
}

谢谢..假设我想用“lanscapeleft”和“landscaperight”怎么写，你能修改答案吗：）谢谢@Martinberger可能的重复
