MPMoviePlayerController not working in iOS4

由 空扰寡人 提交于 2019-12-09 23:29:20
问题 I'm using the first answer from iOS 4 + MPMoviePlayerController to try and get MPMoviePlayerController to play. In the simulator (iPhone device with iOS4), I hear sound but no video. On the device (iPhone 3GS and iOS4), I don't get anything. Here's my code: MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:moviePath]]; moviePlayer.movieControlMode = MPMovieControlModeDefault; if ([moviePlayer respondsToSelector:@selector(view)])

问题 I'm using MPMoviePlayerController to play a video which has audio as well. It's working fine. I'm hiding the default controls. So no controls are showing on the video. I want to place a slider on the video (I successfully placed a slider as well over the video). With the slider, I want to control the volume of the video that is being played. How can I control volume of video? 回答1: See the documentation for MPVolumeView. Here is a sample code that I use in my view controller. MPVolumeView

Check if URL-file exist or not

由 一曲冷凌霜 提交于 2019-12-09 21:47:57
问题 I wonder how I can check if a file exist on a server or not, without downloading the data first. I have around 30 different objects and some of them is connected to a movie on a server. At the moment I use NSData to control if the the URL exist, and then shows the movie, or if it doesn't and then alerts the user that there is no video for that object. The code I use for the moment: NSString *fPath = [[NSString alloc] initWithFormat:@"http://www.myserver/%@", [rows idNr]]; NSURL *videoURL =

MPMoviePlayerViewController playback video after going to background for youtube

由 非 Y 不嫁゛ 提交于 2019-12-08 14:19:28
I have set App Plays Audio for Required background modes in my app's info.plist to keep the mpmovieplayerviewcontroller not dismissing after going to background. It did a great job. However, Apple has rejected my app's update recently, as I set that attribute. Then I keep finding solutions for doing the same job but fail. To deal with it, I save the currentplaybacktime when the view controller receive UIApplicationDidEnterBackgroundNotification -(void)willEnterBackground { NSLog(@"willEnterBackground"); if (self.mp) { playbackTime = self.mp.moviePlayer.currentPlaybackTime; [self.mp

问题 I use MPMoviePlayerViewController to play some videos form the internet. When the user presses home button and the app goes in background, the iphone still downloads a lot of information. Can anyone recomend me how the trafic can be stopped, without disabling multitasking or calling exit(0)? I have tried to stop the MPMoviePlayerViewController, but in some cases, when the MPMoviePlayerViewController is not fully loaded, the it doesn't respond(not the video, the MPMoviePlayerViewController).
