ios - 画中画后如何恢复全屏视频播放器

我正在使用 AVPlayerViewController 和 allowsPictureInPicturePlayback = YES;,

所以当我点击 PictureInPicture 按钮时，AVPlayerViewController 将被关闭并显示小播放器..

但是当我点击小播放器中的恢复按钮时，它会被关闭而不再显示AVPlayerViewController..

那么在小播放器中点击恢复按钮后如何恢复AVPlayerViewController？？

我的代码:

#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>

@interface ViewController ()<AVPlayerViewControllerDelegate>{
    AVPlayerViewController *_AVPlayerViewController;
}

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
    [[AVAudioSession sharedInstance] setActive: YES error: nil];

    // create a movie player
    NSURL *url = [NSURL URLWithString"http://38.96.175.119:1935/aletejahtv/aletejahtv3/playlist.m3u8"];

    _AVPlayerViewController = [AVPlayerViewController new];
    _AVPlayerViewController.delegate = self;
    _AVPlayerViewController.showsPlaybackControls = YES;
    _AVPlayerViewController.allowsPictureInPicturePlayback = YES;
    _AVPlayerViewController.videoGravity = AVLayerVideoGravityResizeAspect;
    _AVPlayerViewController.player = [AVPlayer playerWithURL:url];
    [_AVPlayerViewController.player play];
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        [self presentViewController:_AVPlayerViewController animated:YES completion:nil];
    });
}


- (void)playerViewControllerWillStartPictureInPictureAVPlayerViewController *)playerViewController{
    NSLog(@"playerViewControllerWillStartPictureInPicture");
}

- (void)playerViewControllerDidStartPictureInPictureAVPlayerViewController *)playerViewController{
    NSLog(@"playerViewControllerDidStartPictureInPicture");
}

- (void)playerViewControllerAVPlayerViewController *)playerViewController failedToStartPictureInPictureWithErrorNSError *)error{
    NSLog(@"failedToStartPictureInPictureWithError");
}

- (void)playerViewControllerWillStopPictureInPictureAVPlayerViewController *)playerViewController{
    NSLog(@"playerViewControllerWillStopPictureInPicture");
}

- (void)playerViewControllerDidStopPictureInPictureAVPlayerViewController *)playerViewController{
    NSLog(@"playerViewControllerDidStopPictureInPicture");
}

- (BOOL)playerViewControllerShouldAutomaticallyDismissAtPictureInPictureStartAVPlayerViewController *)playerViewController{
    return YES;
}

- (void)playerViewControllerAVPlayerViewController *)playerViewController restoreUserInterfaceForPictureInPictureStopWithCompletionHandlervoid (^)(BOOL restored))completionHandler{
    NSLog(@"restoreUserInterfaceForPictureInPictureStopWithCompletionHandler");
}

@end

我能够通过在委托(delegate)中的 playerViewController:restoreUserInterfaceForPictureInPictureStopWithCompletionHandler: 中使用 presentViewController: animated: 来解决此问题

所以它会在之前被解除后再次代表AVPlayerViewController

我的新代码:

- (void)playerViewControllerAVPlayerViewController *)playerViewController restoreUserInterfaceForPictureInPictureStopWithCompletionHandler:(void (^)(BOOL restored))completionHandler{
    [self presentViewController:playerViewController animated:YES completion:nil];
    NSLog(@"restoreUserInterfaceForPictureInPictureStopWithCompletionHandler");
}
