將視頻加載到庫中的視圖/緩存

Question

對於我的應用程序我希望用戶錄製將存儲在緩存目錄中的視頻，以便在整個應用程序中重複使用。

NSString *DestFilename = @ "output.mov"; 

//Set the file save to URL 
NSLog(@"Starting recording to file: %@", DestFilename); 
NSString *DestPath; 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); 
DestPath = [paths objectAtIndex:0]; 
DestPath = [DestPath stringByAppendingPathComponent:DestFilename]; 

NSURL* saveLocationURL = [[NSURL alloc] initFileURLWithPath:DestPath]; 
[MovieFileOutput startRecordingToOutputFileURL:saveLocationURL recordingDelegate:self]; 

的NSLog的說：

url = file:///var/mobile/Containers/Data/Application/BD41ABB0-77BA-4872-B447-07906A3C6FA7/Library/Caches/output.mov

我如何可以加載或可能嵌入此視頻爲我的故事板ViewControllers之一？

Answer 1

基本上，你的視頻網址是存在的，所以你可以將視頻加載到您的視圖控制器和2個可能的辦法發揮它：使用的MPMoviePlayerController或AVPlayer

例如從您的視圖控制器

//The first approach 
    self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:saveLocationURL]; 
    [self.moviePlayerController.view setFrame: CGRectMake(0, 0, 1024, 768)]; 
    [self.view addSubview:self.moviePlayerController.view]; 

    [self.moviePlayerController play]; 

    //The second approach 
    self.playerItem = [AVPlayerItem playerItemWithURL:saveLocationURL]; 
    self.player = [AVPlayer playerWithPlayerItem:playerItem]; 

    AVPlayerLayer *layer = [AVPlayerLayer playerLayerWithPlayer:self.player]; 
    layer.frame = CGRectMake(0, 0, 1024, 768); 

    [self.view.layer addSublayer:layer]; 
    [self.player play]; 

希望這會幫助你。
