Question

我正在使用Xcode 7并且具有快速查看功能我遇到了此错误。它说无法加载＆＃34; fileURL＆＃34;这是我的代码 //这里因为下面的行@file被附加到我的fileURL的末尾，就像这样 -

 @"http:/example.com/some_clips/SHAINA%20NC%20NEWS%20X%20180516%201657PM.mp4 -- file:///"    see here something file:/// in the end so because of this i am unable to play video.

如果我使用initWithString并直接提供URL，那么它没有给出错误请建议我在我创建的下面设置我的播放器的URL，请在代码中阅读评论。有没有人对此有所了解。

 NSString *localfilepath=[NSString stringWithFormat:@"%@",[managedObject valueForKey:@"clip_path"]];  //here i am getting my URL path upto .mp4 but after below line word -- file gets attached to it because of fileURLWithPath method don't know how to convert that 


 NSURL *fileURL = [NSURL fileURLWithPath:localfilepath]; //suggest me this line of code so that i can pass URL to the player here this method is not working


// create a player

player = [AVPlayer playerWithURL:fileURL]; //here this fileURL which is going to player is going with that file:/// so giving error and no video runs

AVPlayerViewController *controller = [[AVPlayerViewController alloc] init];

[self addChildViewController:controller];
[self.view addSubview:controller.view];

controller.view.frame = CGRectMake(10,80,300,300);
controller.player = player;
controller.showsPlaybackControls = YES;
[player pause];

Answer 1

您应该使用：

NSURL *fileURL = [NSURL URLWithString:localfilepath];

而不是：

NSURL *fileURL = [NSURL fileURLWithPath:localfilepath];

fileURLWithPath:方法用于创建本地文件（位于设备本身的文件）网址。

我已经成功了:)我找到答案:)这是将视频播放到服务器上的AVPlayer的完整代码

//这里我使用核心数据管理对象获取从服务器下载的所有URL

NSString *localfilepath=[NSString stringWithFormat:@"%@",[managedObject valueForKey:@"clip_path"]];

//然后在下面的行我将它编码为NSUTF8StringEncoding格式不要忘记这样做，否则视频将无法播放，因为它不是我的情况

   NSURL *url = [NSURL URLWithString:[localfilepath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

//及以下我已经为玩家分配了网址并创建了播放器

  player = [AVPlayer playerWithURL:url];

AVPlayerViewController *controller = [[AVPlayerViewController alloc] init];

[self addChildViewController:controller];
[self.view addSubview:controller.view];

controller.view.frame = CGRectMake(10,80,300,300);
controller.player = player;
controller.showsPlaybackControls = YES;
//player.closedCaptionDisplayEnabled = NO;
[player pause];
[player play];

无法加载＆＃34; fileURL＆＃34;的快速浏览数据由于fileURLWithPath方法无法播放AVPlayer视频
