肖像video到风景

我知道像这样的问题可能已经在那里，但为了像我这样的人，我会继续问

我有一个应用程序设置为只允许纵向定位，但是这个设置会影响我的video，因为我只希望video能够在横向上播放。 有没有一种方法可以添加到我的.m文件中来实现这个function？ 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

在你的视图控制器.m文件中，你应该有

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

在那里你可以返回YES支持的方向，这将使您可以旋转video。

也不是说，如果你使用UINavigationController，这个aproach将无法正常工作，除非UINavigationControllerpipe理的所有视图实现- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation同样的方式。

同样在您的目标 – >“您的项目” – >摘要中，您可以设置支持的方向。

编辑：去这里寻找UIInterfaceOrientation。 你有你需要的常量。

我会写这样的：

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