我怎樣才能啓動從MPMoviePlayerController解析下載的視頻

Question

我怎樣才能播放視頻使用MPMoviePlayerController下載解析保存爲PFFile？ 我下載這段代碼的視頻文件：

var query = PFQuery(className:"Video") 
    query.whereKey("Nome", equalTo:"prova") 
    query.findObjectsInBackgroundWithBlock { 
     (objects: [AnyObject]?, error: NSError?) -> Void in 

     if error == nil { 
      // The find succeeded. 
      println("Successfully retrieved \(objects!.count) scores.") 
      if let objects = objects as? [PFObject] { 
       for object in objects { 
        var imageFile:PFFile =object.objectForKey("Video") 
        imageFile.getDataInBackgroundWithBlock { 
         (imageData: NSData?, error: NSError?) -> Void in 

        ????????????? 
        } 

      } 
     } else { 
      println("Error: \(error!) \(error!.userInfo!)") 
     } 
    }

可以保存數據的臨時文件目錄，並從 NSString *strLocation = [@"~/Documents/downloadedFile.mov" stringByExpandingTildeInPath]; // Use Your Downloaded Data [data writeToFile:strLocation atomically:YES]; // Pass URL of that saved file in Player MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:strLocation]];

希望這有助於你播放視頻。
