AVPlayerviewcontroller ios目标c-Java 学习之路

我有一个ipad iphone的应用程序，ipad用户总是启用横向模式和iphone用户的肖像，现在我想要实现的是在iphone应用程序中我使用AVPlayerViewController播放视频但是因为应用程序被锁定在肖像里面appdelegate，当我按下播放器上的全屏按钮时它将保持opn肖像模式我想让它成为风景我尝试了所有我在stackoverflow中找到的答案，但没有运气任何想法如何让它工作？

在 AppDelegate.m 文件中添加以下代码 .

Objective C

#if __IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_9_0
#define supportedInterfaceOrientationsReturnType NSUInteger
#else
#define supportedInterfaceOrientationsReturnType UIInterfaceOrientationMask
#endif

- (supportedInterfaceOrientationsReturnType)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)windowx
{
    if ([[self.window.rootViewController presentedViewController] isKindOfClass:[AVPlayerViewController class]]
        )
    {
        if ([self.window.rootViewController presentedViewController].isBeingDismissed)
        {
            return UIInterfaceOrientationMaskPortrait;
        }else{
            return UIInterfaceOrientationMaskAll;
        }
    }
}

Swift

#if __IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_9_0
let supportedInterfaceOrientationsReturnType = NSUInteger
#else
let supportedInterfaceOrientationsReturnType = .mask
#endif

func application(_ application: UIApplication, supportedInterfaceOrientationsFor windowx: UIWindow) -> supportedInterfaceOrientationsReturnType {
    if (self.window!.rootViewController!.presented! is AVPlayerViewController) {
        if self.window!.rootViewController!.presented!.isBeingDismissed() {
            return .portrait
        }
        else {
            return .all
        }
    }
}

我用NSTimer解决了这个问题我做了一个方法，每隔一段时间就会调用一次我知道不是很好的做法，但这就是我所做的：

[NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:@selector(yourMethod) userInfo:nil repeats:YES];

-(void)yourMethod{
if(!_fullscreen){
    [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];
}else{
    [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
}   }

_fullscreen是一个标志，当AVplayer进入全屏视图或普通视图时会改变 .

为了跟踪AV播放器状态，我使用Observer @“bounds”来检查AVPlayer屏幕的大小 .

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSString *, id> *)change context:(void *)context {
if (object == self.playerViewController.contentOverlayView) {
    if ([keyPath isEqualToString:@"bounds"]) {
        CGRect oldBounds = [change[NSKeyValueChangeOldKey] CGRectValue], newBounds = [change[NSKeyValueChangeNewKey] CGRectValue];
        BOOL wasFullscreen = CGRectEqualToRect(oldBounds, [UIScreen mainScreen].bounds), isFullscreen = CGRectEqualToRect(newBounds, [UIScreen mainScreen].bounds);
        if (isFullscreen && !wasFullscreen) {
            if (CGRectEqualToRect(oldBounds, CGRectMake(0, 0, newBounds.size.height, newBounds.size.width))) {
                NSLog(@"rotated fullscreen");
            }
            else {
                NSLog(@"entered fullscreen");

                if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){

                }else{
                    _fullscreen = YES;
                    [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
                }
            }
        }
        else if (!isFullscreen && wasFullscreen) {
            NSLog(@"exited fullscreen");
            if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){

            }else{
                _fullscreen = NO;
                [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];

            }
        }
    }
}}
