Question

我正在尝试以横向模式播放来自youtube的视频。我左右关闭了横向以获得支持的设备方向，因为如果它已打开，则每个视图都可以进行横向显示。我正在为iOS 6构建此功能。如何在横向播放视频。

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];
}

修改

我做了以下事情：

制作新课程

AboutNavViewController（它是UiNavigationController的子类）

#import "AboutNavViewController.h"

@interface AboutNavViewController ()

@end

@implementation AboutNavViewController


- (BOOL)shouldAutorotate {
    return NO;
}

- (BOOL)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}
@end

在我的aboutviewcontroller（它是uiviewcontroller的子类）

#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

我收到以下错误：

对于开始/结束外观转换的不平衡调用。

我做错了什么？

Answer 1

注意：您必须在Info.plist中向左侧和右侧添加支持的界面方向才能使其生效。

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方向。

从之前的回答“

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

如何让我的MPMoviePlayerController在Landscape中播放？
