I am developing an iPhone application in which I will store stream video from URL directly to cache in local, now I need to play video in movie-player while it was in downloading in cache. I followed this http://lists.apple.com/archives/cocoa-dev/2011/Jun/msg00844.html, but I couldn't do exact. I am able to download video in cache but I couldn't play video from cache. So how can I play while its downloading?

推荐答案

如果你使用arc
添加t .h文件

if you are using arc add in t .h file

@property (nonatomic, strong) MPMoviePlayerController *controller;

并查看最后一行。祝你好运

and take a look at the last line. good luck

NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"Man of Steel" ofType:@"mp4"];
NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];

[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];

[moviePlayerController.view setFrame:CGRectMake(0,0,500,500)];

[self.view addSubview:moviePlayerController.view];
//moviePlayerController.fullscreen = YES;

//moviePlayerController.scalingMode = MPMovieScalingModeFill;

[moviePlayerController play];

[self setController:moviePlayerController];
}
