纵向视频转横向

Question

我知道这样的问题可能已经存在，但为了像我这样的其他人，我会继续问

我有一个应用程序设置为仅允许纵向，但此设置会影响我的视频，因为我希望只有视频也可以横向播放。有没有一种方法可以添加到我的 .m 文件中来完成这项工作？这是我的代码；

 #import "BIDVideosViewController.h"

 @interface BIDVideosViewController ()


 @end

 @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;
 }


 - (void)viewDidLoad
 {
 [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];

 }

 - (void)didReceiveMemoryWarning
 {
 [super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
 }

 -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
 return [tableList count];
 }

 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 {
 static NSString *DisclosureButtonIdentifier = @"DisclosurebutotonIdentifier";
 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;
 }




 -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
{
    NSBundle *str = [tableList objectAtIndex:indexPath.row];
    if ([str isEqual:@"Gangan"])
    {
        NSBundle *bundle = [NSBundle mainBundle];
        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];
    }

   }
   }
   @end

在您的视图控制器 .m 文件中，您应该有

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

您可以在此处返回 YES 以获取支持的方向，这将使您能够旋转视频。

如果你使用 UINavigationController，这种方法也不会起作用，除非UINavigationController 管理的所有视图都以相同的方式实现- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation。

同样在你的 Targets -> “You Project” -> Summary，你可以设置支持的方向。

编辑： 去here 寻找 UIInterfaceOrientation。那里有你需要的常量。

我会这样写：

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