iphone - Why can't I capture a screenshot of MPMoviePlayerController? -

-

I need to capture a screen shot of a video game in the mpmovieplayer controller, but whatever I get is one The red screen is (I created the red background and the cover scene with 0.5 alpha).

Here is the code: 

  NSArray * windows = [[UIApplication shared application] window]; If ([windows count]> 1) {UIWindow * moviePlayerWindow = [[UIApplication shared application] keyWindow]; UIView * coverView = [[UIView alloc] initWithFrame: Movie Player Window.bounds]; [Main Controller Movie player pauses]; // Without that it will not work too! CoverView.backgroundColor = [UIColor redColor]; CoverView.alpha = 0.5; [Movieplayerviewview: coverview]; UIGraphicsBeginImageContext (coverView.bounds.size); [CoverView.layer renderInContext: UIGraphicsGetCurrentContext ()]; UIImage * Screenshots; Screenshots = UGraphicsGetImageFrintIngeTextEX (); UIGraphicsEndImageContext (); UIImageWriteToSavedPhotosAlbum (screenshot, own, zero, zero); }

Any ideas ???

Thanks

Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
