I'm trying to use the same button to play and stop my radio stream, my button plays fine, then when i press for it to stop, it only stops for a few seconds then starts playing again.
here is the code im using.
- (IBAction)playStream:(id)sender {
self.buttonPressed.selected = !self.buttonPressed.selected;
NSString *urlAddress = #"http://67.159.28.74:8730";
NSURL *url = [NSURL URLWithString:urlAddress];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL:url];
player.movieSourceType = MPMovieSourceTypeStreaming;
player.view.hidden = YES;
self.myPlayer = player;
[self.view addSubview:self.myPlayer.view];
if (player.playbackState == MPMoviePlaybackStateStopped){
[self.myPlayer play];}
else if (player.playbackState == MPMoviePlaybackStatePlaying){
[self.myPlayer stop];}
}
Every time you press the button, a new instance of the movie player is created. Thus the check if (player.playbackState == MPMoviePlaybackStateStopped) will always return YES, and thus start the movie.

I've got an application that currently uses the UIWebview to play audio, which works even if the device is locked as I enable mediaPlaybackAllowsAirPlay.
However I started to move the code to use the new WKWebView and I've enabled mediaPlaybackAllowsAirPlay, However when I press the lock button, the WebView stops playing the audio.
Any ideas how I can get WKWebview to behave like the UIWebView?
Update, Here's an example of my code:
WKUserContentController *wkUController = [[WKUserContentController alloc] init];
WKWebViewConfiguration *theConfiguration = [[WKWebViewConfiguration alloc] init];
theConfiguration.userContentController = wkUController;
theConfiguration.allowsAirPlayForMediaPlayback = YES;
webViewActive = [[WKWebView alloc] initWithFrame:viewForWeb.frame configuration:theConfiguration];
webViewActive.navigationDelegate = self;
webViewActive.frame = viewForWeb.bounds;
[webViewActive setAutoresizingMask: UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth];
[viewForWeb addSubview:webViewActive];
NSURL *nsurl=[NSURL URLWithString:#"URL TO AUDIO"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[webViewActive loadRequest:nsrequest];
Thanks
First I couldn't find anyone else having this problem. Working on a game in spritekit - there is a mainTitle.h/m and gamePlay.h/m files. Below is code for the share button to share your progress via text, fb, twitter, ect. The code below is located in the gamePlay.m inside a touch method. The code works however after the user selects to send his/her score view text message - the new message window slides up and then the game appears to restart and load mainTitle.m scene. Any ideas as to why this happens?
-(void)share {
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, 1.0);
[self.view.drawViewHierarchyInRect:self.view.boundsafterScreenUpdates:YES];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSString *message = [NSString stringWithFormat:#"messge"];
NSString *urlString = [NSString stringWithFormat#"www..."];
NSURL *gmURL = [NSURL URLWithString:urlString];
UIActivityViewController *actVC = [[UIActivityViewController alloc]
initWithActivityItems:#[message, gmURL, image] applicationActivites:nil];
actVC.excludedActivityTypes = #[UIActivityTypePrint, UIActivityTypeAriDrop];
UIViewController *viewControl = self.view.window.rootViewController;
[viewControl presentViewController:actVC animated:YES completion:nil];
}
-(void)touchBegins ... {
[self share];
}
Probably its not a good idea to call share method in touchBegan, since it might be fired multiple times in some conditions. Use i.e. UIButton instead
I am making app like Instagram .i am using GPUImage framework ,in this i have to take photos and videos and share. i able to capture photos using this framework and now i have to capture video but i am struggling how to change camera mode photos to video. any help and tutorial then its very good for me. I used this code camera for photos mode.
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
self.imagepicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[[NSBundle mainBundle] loadNibNamed:#"OverlayView" owner:self options:nil];
self.overlayView.frame = self.imagepicker.cameraOverlayView.frame;
self.imagepicker.cameraOverlayView = self.overlayView;
self.overlayView = nil;
CGSize result = [[UIScreen mainScreen] bounds].size;
self.imagepicker.showsCameraControls = NO;
self.imagepicker.allowsEditing = NO;
self.imagepicker.wantsFullScreenLayout = NO;
// self.imagepicker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
}
else{
self.imagepicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
In my case, I'm using GPUImage to do both (pictures and videos). Therefore I've created two objects: one of type GPUImageStillCamera(pictures) and other of type GPUImageVideoCamera (videos).
So whenever you need to switch between cameras you basically stop the GPUImageStillCamera capture and initialize a video camera (note that you have to adapt this snippet to your project):
func initializeVideoCamera() {
// Stop the capture of GPUImageStillCamera
stillCamera.stopCameraCapture()
videoCamera = GPUImageVideoCamera.init(sessionPreset: AVCaptureSessionPreset1920x1080, cameraPosition: .Back)
videoCamera?.outputImageOrientation = .Portrait
videoCamera?.addTarget(filter)
// If a file already exists, AVAssetWriter won't let you record new frames, so delete the old movie
unlink(pathToMovieFile)
initializeWriteWithPath(pathToMovieFile)
videoCamera?.startCameraCapture()
}
I am making an application in which i am trying to play a video. The video starts properly but the video screen changes in black color after 4 sec. I dont know what is the problem.
also when i am setting player.movieplayer.shouldautoplay = NO, there is no effect of this line, video starts automatically.
Here is Code:
NSString *urlString = [[NSBundle mainBundle] pathForResource:#"Movie" ofType:#"m4v"];
NSURL *urlObj = [NSURL fileURLWithPath:urlString];
UIGraphicsBeginImageContext(CGSizeMake(1,1));
MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:urlObj];
UIGraphicsEndImageContext();
[player.view setBounds:self.view.bounds];
// when playing from server source type shoud be MPMovieSourceTypeStreaming
[player.moviePlayer setMovieSourceType:MPMovieSourceTypeStreaming];
[player.moviePlayer setScalingMode:MPMovieScalingModeAspectFill];
player.moviePlayer.shouldAutoplay = NO;
[self.view addSubview:player.view];
[player.moviePlayer play];
Am i missing something here??
I tried to get the total duration of video (using duration property of mpmovieplayercontroller) but its showing 0.0. how to get the duration of video??
NSString *urlString = [[NSBundle mainBundle] pathForResource:#"Movie" ofType:#"m4v"];
NSURL *urlObj = [NSURL fileURLWithPath:urlString];
UIGraphicsBeginImageContext(CGSizeMake(1,1));
MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:urlObj];
UIGraphicsEndImageContext();
[player.view setBounds:self.view.bounds];
// when playing from server source type shoud be MPMovieSourceTypeStreaming
[player.moviePlayer setMovieSourceType:MPMovieSourceTypeStreaming]; // I was missing this line therefore video was not playing
[player.moviePlayer setScalingMode:MPMovieScalingModeAspectFill];
[self.view addSubview:player.view];
[player.moviePlayer play];
There are several issues here:
For this type of usage (integrating the player into your view), you should be using MPMoviePlayerController, not MPMoviePlayerViewController. Use MPMoviePlayerViewController when you want to have a self-contained view controller which can be presented using presentMoviePlayerViewControllerAnimated:.
Assuming you are using ARC, the main problem is that nothing is keeping a reference to your player object. As a consequence, the player is disappearing shortly after you create it. You should keep a reference to it by assigning it to a property or instance variable of your view controller.
For a full example of this, see Till's excellent answer to a similar question.
I'm not sure what your intended purpose of the UIGraphicsBeginImageContext and UIGraphicsEndImageContext calls are, but I can't see that they're needed here.
As for shouldAutoplay = NO, the video is still starting because you are calling play immediately afterwards.
The player's duration property only contains a useful value after a MPMovieDurationAvailableNotification has been received. You'll need to do something similar to the following to have access to the actual duration:
__weak MediaPlayerController *weakSelf = self;
[[NSNotificationCenter defaultCenter] addObserverForName:MPMovieDurationAvailableNotification object:self.player queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *note) {
NSLog(#"Movie duration: %lf", weakSelf.player.duration);
}];
Use removeObserver:name:object: to remove the observer when you are done.
I'm working on a matching program for iPad and when a user selects a button an image is "uncovered" and then when the user selects a second button,another image is uncovered. I then programmatically check for a match and if not, revert both button images back to their initial state.
This is working fine except when a match is NOT made, the switch happens so fast that you do not have time to see what you have "uncovered". I tried to make it sleep but the image doesn't ever swap to the uncovered state... Thoughts?
The code for this is as follows:
//Take action on the tap of one of the buttons
if(isFirstSelection)
{
firstSelection = [(UIButton *)sender tag];
tempImageItem = [tileArray objectAtIndex:firstSelection];
tempImage = [tempImageItem tileImage];
firstSelectionName = [[NSString alloc] initWithString:[tempImageItem tileName]];
[(UIButton *)sender setImage:tempImage forState:UIControlStateNormal];
tempButton = sender;
isFirstSelection = NO;
}else{
secondSelection = [(UIButton *)sender tag];
tempImageItem = [tileArray objectAtIndex:secondSelection];
tempImage = [tempImageItem tileImage];
secondSelectionName = [[NSString alloc] initWithString:[tempImageItem tileName]];
[(UIButton *)sender setImage:tempImage forState:UIControlStateNormal];
//Two game pieces have been removed so check to see if they are a match
if([firstSelectionName isEqualToString:secondSelectionName])
{
//Match found
//do something
}else{
**//NO MATCH FOUND
[NSThread sleepForTimeInterval:3];
//Display the checker board pieces again
[(UIButton *)sender setImage:[UIImage imageNamed:#"originalImage"] forState:UIControlStateNormal];**
}
//Reset isFirstSelection Flag to YES for next selection
isFirstSelection = YES;
}
From what i understand you want to put the button's original image after 3 seconds so the user has the time to see what happened.
You should look at the NSTimer class to trigger that code
[(UIButton *)sender setImage:[UIImage imageNamed:#"originalImage"] forState:UIControlStateNormal];
in 3 seconds from now.
For "run this code in X seconds" I prefer:
[self performSelector:#selector(spinWheel:) withObject:[NSNumber numberWithUnsignedInt:0] afterDelay:delay];
no need to muck around with timer objects.
