[英]How to get rootViewController in iOS 13 using Objective-C?
[英]Cannot get AVPlayerLayer on iOS13.x by Objective-C
我正在使用 objective-c 制作 iOS 应用程序。
请告诉我如何在 iOS13.x 环境中修复 AVPlayerView。
ViewController.m 写
AVPlayerLayer* layer = (AVPlayerLayer*)self.videoView.layer;
VideoView 包含 AVPlayerView
AVPlayerView.m 写
#import "AVPlayerView.h"
#import <AVFoundation/AVFoundation.h>
@implementation AVPlayerView
+(Class)layerClass{
return AVPlayerLayer.class;
}
@end
由于某种原因没有调用 layerClass 方法。
此外, (AVPlayerLayer *) self.videoView.layer 返回的 class
AVPresentationVontainerViewLayer。
我想要一个 AVPlayerView class。
我应该如何解决?
尝试这个:
NSURL *url = [NSURL fileURLWithPath:path];
AVPlayer *player = [AVPlayer playerWithURL:url];
AVPlayerViewController *AVPlayerVc = [[AVPlayerViewController alloc] init];
AVPlayerVc.player = player;
if (AVPlayerVc) {
[self presentViewController:AVPlayerVc animated:YES completion:^{
[player play];
}];
}
Swift 版本:
let player = AVPlayer(url: YOUR_URL)
let playerController = AVPlayerViewController()
playerController.player = player
present(playerController, animated: true) {
player.play()
}
