I have 2 buttons, 1 turns to the next page and should play a sound at the same time but the sound doesn't seems to be working, I need your help on this please.
I have 4 pages and in each page there is a play button that play or stop the audio, but if I press play and press next to the next page, the audio will keep playing, how do I do so that if I press the next button, it will stop the music automatically.
Thanks for your help, find below the code.
- (IBAction)next {
// This part plays the next page turn noise
NSURL *this = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/next.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:this error:&error];
[audioPlayer setDelegate:self];
audioPlayer.numberOfLoops = 0;
[audioPlayer play];
// This part takes us to the next view
Rabbana2 *rab = [[Rabbana2 alloc] initWithNibName:#"Rabbana2" bundle:nil];
[UIView beginAnimations:#"flipView" context:Nil];
[UIView setAnimationDuration:2];
[UIView setAnimationCurve:UIViewAnimationOptionCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
[self.view addSubview:rab.view];
[UIView commitAnimations];
}
// This button plays the audio
- (IBAction)play {
if(clicked == 0){
clicked = 1;
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/rabbana1.wav", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[audioPlayer setDelegate:self];
audioPlayer.numberOfLoops = 0;
[audioPlayer play];
[start setImage:[UIImage imageNamed:#"Sstop.png"] forState:UIControlStateNormal];
}
else{
[audioPlayer release];
clicked = 0;
[start setImage:[UIImage imageNamed:#"Pplay.png"] forState:UIControlStateNormal];
}
}
//If user does not do anything by the end of the sound set the button to start
- (void) audioPlayerDidFinishPlaying: (AVAudioPlayer *) player
successfully: (BOOL) flag {
if (flag==YES) {
clicked = 0;
[start setImage:[UIImage imageNamed:#"Pplay.png"] forState:UIControlStateNormal];
}
}
In your method which handles the page turn, you need to stop the current playing sound by using [audioPlayer stop] if it is playing

Basically in app have a play button for audio file, want to add another UIButton Besides Play button so that whenever it is pressed it will repeat audio file for some number of times or may be infinite until it is pressed again to stop repetition of playing audio file. How can this be achieved.
Below is the code for play/pause toggle button
_playButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_playButton addTarget:self action:#selector(playAction:) forControlEvents:UIControlEventTouchUpInside];
_playButton.frame = CGRectMake(80, 40, 25, 25);
[_playButton setImage:[UIImage imageNamed:#"1play.png"] forState:UIControlStateNormal];
[_playButton setImage:[UIImage imageNamed:#"audiopause.png"] forState:UIControlStateSelected];
UIBarButtonItem *play = [[UIBarButtonItem alloc] initWithCustomView:_playButton];
// Get the file path to the song to play.
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"Theme"ofType:#"mp3"];
// Convert the file path to a URL.
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
//Initialize the AVAudioPlayer.
player = [[AVAudioPlayer alloc]
initWithContentsOfURL:fileURL error:nil];
player.delegate = self;
- (void)playAction:(id)sender
{
if([player isPlaying])
{
[sender setImage:[UIImage imageNamed:#"1play.png"] forState:UIControlStateSelected];
[player pause];
//[timer invalidate];
//timer = nil;
//[self pauseTimer];
}else{
[sender setImage:[UIImage imageNamed:#"audiopause.png"] forState:UIControlStateNormal];
[player play];
slidertimer = [NSTimer timerWithTimeInterval:1.0 target:self selector:#selector(updateProgressBar:) userInfo:nil repeats:YES];
[[NSRunLoop mainRunLoop] addTimer:slidertimer forMode:NSRunLoopCommonModes];
timer = slidertimer;
}
}
It looks like all you need is to execute an action every x number of seconds. You can move the code the UIButton is executing to a method, and then have a NSTimer looping that executes that method for n number of times, then invalidate the NSTimer when you are done.
I have finally worked it out like this
-(void) RepeatAction:(id)sender{
if (player && player.playing) {
[player stop];
player = nil;
[_playButton setImage:[UIImage imageNamed:#"1play.png"] forState:UIControlStateNormal];
return;
}
// Get the file path to the song to play.
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"Theme"ofType:#"mp3"];
// Convert the file path to a URL.
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
//Initialize the AVAudioPlayer.
player = [[AVAudioPlayer alloc]
initWithContentsOfURL:fileURL error:nil];
player.delegate = self;
player.numberOfLoops = -1;
[player play];
}
Now only problem i m facing is that play/pause toggle button is disturbed with this. How to fix that.
My previous code was
- (void) playaudio: (id) sender
{
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"Theme"
ofType:#"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
self.audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:fileURL error:nil];
self.audioPlayer.currentTime = 0;
[self.audioPlayer play];
}
- (void)pause: (id)sender
{
[audioPlayer pause];
}
- (void)stop: (id)sender
{
[audioPlayer stop];
}
In the above code pause button was acting as stop button rather than pause where it was supposed to resume the audio file.
Now i have added simple statements to my code it is working to some extent but still not upto my expectations.
What happening now is when you play audio file and click on pause button nothing happens but when you click on the stop button it stops playing audio file and then when you press the pause button it resumes the audio file from where it was stopped by pressing stop button. Why is that when you press stop buttons only then pause button functions but not before that. I don't get this why?
Any ideas why this is happening
- (void)pause: (id)sender
{
[audioPlayer pause];
[audioPlayer prepareToPlay];
[audioPlayer play];
}
- (void) stop: (id) sender
{
[audioPlayer stop];
}
If anyone have any ideas that why this is happening. Will appreciate help.
Thanks in advance.
You shouldn't be recreating the audio file every time you play it. Here is how you could do this:
- (void) playaudio: (id) sender
{
if(self.audioPlayer == nil) {
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"Theme"
ofType:#"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
self.audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:fileURL error:nil];
self.audioPlayer.currentTime = 0; //this could be outside the if if you want it to start over when they hit play
}
[self.audioPlayer play];
}
- (void)pause: (id)sender
{
if([audioPlayer isPlaying]){
[audioPlayer pause];
} else {
[audioPlayer play];
}
}
- (void)stop: (id)sender
{
[audioPlayer stop];
}
Hi there I'm trying to play a page turn sound when I click on the "next" button to take me to the next page, but the sound does not come, while when I press the "play" button for the music, it plays the music, can anyone help here please.

I would ensure that your audio file is properly encoded. It is possible your code is executing the playback, but because you might have an audio file improperly encoded it won't play.
Here is a command line conversion to convert a wav file to caf (which iphones love)
afconvert -f caff -d LEI16#44100 -c 1 in.wav out.caf
How can I play a sound with an IBAction by pressing on a UIbutton once and pause it by pressing the button again using AVAudioPlayer? Also I want to change the state of that UIButton when the sound is playing and when it's not.
Here's my code:
- (IBAction)Beat
{
if ([Media2 isPlaying])
{
[Media2 pause];
[Button17 setSelected:NO];
}
else
{
Path = [[NSBundle mainBundle] pathForResource:#"Beat" ofType:#"mp3"];
AVAudioPlayer *Media2 = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:Path] error:NULL];
[Media2 setDelegate:self];
[Media2 play];
[Button17 setSelected:YES];
}
}
Here's is simple method using BOOL Variable.
Set playing = NO in viewDidLoad.
-(void)PlayStop{
if (playing==NO) {
// Init audio with playback capability
[play setBackgroundImage:[UIImage imageNamed:#"hmpause.png"] forState:UIControlStateNormal];
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:______ error:&err];
[audioPlayer prepareToPlay];
audioPlayer.delegate=self;
[audioPlayer play];
playing=YES;
}
else if(playing==YES){
[play setBackgroundImage:[UIImage imageNamed:#"Audioplay.png"] forState:UIControlStateNormal];
[audioPlayer pause];
playing=NO;
}
}
Keep your audioPlayer instance ready to play using the below method.
/*
Prepares the audio file to play.
*/
-(void) initWithAudioPath:(NSString *) audioPath {
// Converts the sound's file path to an NSURL object
NSURL *audioPathURL = [[NSURL alloc] initFileURLWithPath:audioPath];
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioPathURL error:nil];
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
[audioPathURL release];
}
-(void) pausePlaybackForPlayer:(AVAudioPlayer *) player {
[player pause];
}
-(void) startPlaybackForPlayer:(AVAudioPlayer *) player {
if (![player play]) {
NSLog(#"Could not play %#\n", player.url);
}
}
- (IBAction)Beat {
if (audioPlayer.playing == NO) {
// Audio player is not playing.
// Set the button title here to "stop"...
[self startPlaybackForPlayer:audioPlayer];
}else {
// Audio player is playing.
// Set the button title here to "play"...
[self pausePlaybackForPlayer:audioPlayer];
}
}
i am an n00b and seeking help.
Now i can start a Soundfile with Following code:
- (void)addButtonSpeaker {
UIButton *buttonSpeaker = [UIButton buttonWithType:UIButtonTypeCustom];
[buttonSpeaker setFrame:CGRectMake(650, 930, 63, 66)];
[buttonSpeaker setBackgroundImage:[UIImage imageNamed:#"buttonLesen.png"]
forState:UIControlStateNormal];
[buttonSpeaker addTarget:self action:#selector(playAudio)
forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:buttonSpeaker];
}
- (void)playAudio {
NSString *path = [[NSBundle mainBundle] pathForResource:#"Vorwort" ofType:#"mp3"];
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL
fileURLWithPath:path] error:NULL];
self.audioPlayer = theAudio;
[theAudio release];
[theAudio play];
}
With the same Button i would like to stop and play the sound.
Maybe i am searching for the wrong thing, but i can´t find the proper information on the web.
It would be really helpful if someone could give me a LINK to a tutorial or something like this.
thanks in advance

Create the AVAudioPlayer player object on loadView or somewhere.
- (void)loadView {
// Some code here
NSString *path = [[NSBundle mainBundle] pathForResource:#"Vorwort" ofType:#"mp3"];
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
self.audioPlayer = theAudio;
[theAudio release];
// Some code here
}
Then inside the button's action(change the action name to toggleAudio as others suggested), you can get the property isPlaying to see whether audio is playing or not, and do the respective actions.
- (void)toggleAudio { // original name is playAudio
if ([self.audioPlayer isPlaying]) {
[self.audioPlayer pause];
// Or, [self.audioPlayer stop];
} else {
[self.audioPlayer play];
}
}
