I added a button to my storyboard, and assigned a music to be played when the button is clicked. I used the event touch up inside
My question is, how can I make the button to toggle the music on and off when it is clicked.
Thanks

For those of you who are interested in seeing the App, I made a repository on github. Here's the link https://github.com/edwinlimantara/IncrediboxV2. Please contribute, if you feel it is an interesting project.
I tried to make something similar to http://incredibox.com/v2/. Check it out! It is a very cool website.
If you are using AVAudioPlayer you can toggle the music player on button tap like:
if(audioPlayer.isPlaying){
[audioPlayer stop];
audioPlayer = nil;
}else{
// initialize audio player and play
}
You can do like below, say below method is called on button tap event then,
-(IBAction)pushClicked:(id)sender
{
UIButton *mButton = (UIButton*)sender;
if (mButton.selected==NO)
{
[mButton setSelected:YES];
//do your stuff here;
}
else if (mButton.selected==YES)
{
[mButton setSelected:NO];
// do your stuff here
}
}
Better you can use UISwitch rather than button to toggle.
If you want to use UIButton then you can use tags and and two different images.
if(soundButton.tag == 1)
{
if(audioPlayer.isPlaying){
[audioPlayer stop];
audioPlayer = nil;
soundButton.tag = 0;
// Change the button image to Off
}
else{
// initialize audio player and play
}
}
else
{
soundButton.tag = 1;
// Play the music & Change the button image to ON
}

I am using AVPlayer to play music in my code. I know I can use MPVolumeView from MediaPlayer to route between speakers, but I am looking for something different(Because I am developing the application in Ionic and I am not able to find some plugin that can perform such thing, plugin which I use is cordova-plugin-media).
I have searched about how to create it and found some answers like I can switch using AVAudioSession.
I am not able to find some code related to it so if anyone can help it would be great.
Another thing is that if I change this forcefully how will it behave with Control Center.
You can still use MPVolumeView with IONIC as plugin, you just need to control UITouchUpInside through code.
Check this if helps.
- (void) currentOutputs:(CDVInvokedUrlCommand*)command {
if(!mpVolumeView){
mpVolumeView = [[MPVolumeView alloc] initWithFrame:CGRectZero];
mpVolumeView.showsVolumeSlider = FALSE;
[self.webView.superview addSubview:mpVolumeView];
[mpVolumeView setAlpha:0.01];
}
UIButton* btn = nil;
for (UIView *view in [mpVolumeView subviews]){
if ([view.class.description isEqualToString:#"MPButton"]){
btn = (UIButton*)view;
break;
}
}
if(btn){
[btn sendActionsForControlEvents:UIControlEventTouchUpInside];
}
}

Have you tried this?
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionPortBluetoothA2DP)
} catch _ {
}
This maybe helpful.
When the accessibility option is turned on the device, we're not able to turn off the closed caption by setting the closedCaptionEnabled option for the AVPlayer instance as we normally would. Is there a way to bypass such option or even to test if it's enabled to lock the CC button if necessary?
You can iterate through each AVPlayerItemTrack and enable/disable it as you wish.
This is how I do in one of my project. I show table of available CC tracks and when the user selects one I iterate through each track, enable the on that user selected and disable rest.
//_selectedTrackIndex = userSelectedIndex;
-(void) setSelectedTrackEnabled {
for (AVPlayerItemTrack * t in [_playerItem tracks]) {
if (counter == _selectedTrackIndex) {
[t setEnabled:YES];
} else {
[t setEnabled:NO];
}
}
}
I'm developing a radio streaming app with XCode 4.5 for iOS 6 and mainly using storyboards.
I successfully made it to be able to play in background. So wherever I go from my app, whether to other tabs or even after clicking the Home button on the simulator,it keeps playing.
I'm using Matt Gallagher's audio streamer, which I include in my app delegate .m file below
#pragma mark - audio streaming
- (void)playAudio:(indoRadio *)np withButton:(NSString *)currentButton
{
if ([currentButton isEqual:#"playbutton.png"])
{
[self.nowplayingVC.downloadSourceField resignFirstResponder];
[self createStreamer:np.URL];
[self setButtonImageNamed:#"loadingbutton.png"];
[audioStreamer start];
}
else
{
[audioStreamer stop];
}
}
- (void)createStreamer:(NSString *)url
{
if (audioStreamer)
{
return;
}
[self destroyStreamer];
NSString *escapedValue = (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes(nil,(CFStringRef)url,NULL,NULL,kCFStringEncodingUTF8);
NSURL *streamurl = [NSURL URLWithString:escapedValue];
audioStreamer = [[AudioStreamer alloc] initWithURL:streamurl];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(playbackStateChanged:)
name:ASStatusChangedNotification
object:audioStreamer];
}
- (void)playbackStateChanged:(NSNotification *)aNotification
{
NSLog(#"playback state changed? %d",[audioStreamer isWaiting]);
if ([audioStreamer isWaiting])
{
[self setButtonImageNamed:#"loadingbutton.png"];
}
else if ([audioStreamer isPlaying])
{
[self setButtonImageNamed:#"stopbutton.png"];
}
else if ([audioStreamer isIdle])
{
[self destroyStreamer];
[self setButtonImageNamed:#"playbutton.png"];
}
}
- (void)destroyStreamer
{
if (audioStreamer)
{
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:ASStatusChangedNotification
object:audioStreamer];
[audioStreamer stop];
audioStreamer = nil;
}
}
- (void)setButtonImageNamed:(NSString *)imageName
{
if (!imageName)
{
imageName = #"playButton";
}
self.nowplayingVC.currentImageName = imageName;
UIImage *image = [UIImage imageNamed:imageName];
[self.nowplayingVC.playBtn.layer removeAllAnimations];
[self.nowplayingVC.playBtn setImage:image forState:0];
if ([imageName isEqual:#"loadingbutton.png"])
{
[self.nowplayingVC spinButton];
}
}
The problem I got is that when I click the play button, it starts the audio streamers but doesn't change into either loading button or stop button. This makes me unable to stop the audio since the button image is not changed. And since I put an NSLog inside the playbackStateChanged: method,I know that the playback state did change. It seems like the setButtonImagedNamed: method is not firing. Any thoughts?
Please have look of my answer:Disabled buttons not changing image in
For a button there is normal, selected, highlighted and disabled state.
So in your case you have to handle the normal and selected state.
In the xib, set image to a button for normal and selected state.
Now in the function of playAudio instead of checking the image name check the button state as below:
- (void)playAudio:(indoRadio *)np withButton:(NSString *)currentButton
{
if (playButton.selected)
{
//Stop the streaming
//set selection NO
[playButton setSelected:NO];
}
else
{
//Start the streaming
//set selection YES
[playButton setSelected:YES];
}
}
playButton is the IBOutlet of play button.
As you have set the images in xib, so the image automatically get changed as per the state of the image
In case you have added the playBtn programmatically, check if the button is declared as weak or its getting released somewhere. If it is weak, make it strong.
In case the button is in the nib file, then the problem is in the IBOutlet. Redo the connection properly.
It turned out that the delegate didn't know which nowplayingVC I was calling. #sarp-kaya's question about Calling a UIViewController method from app delegate has inspired me.
I actually have put this code in my view controller viewDidLoad:
myAppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
but I forgot to add this line:
appDelegate.nowplayingVC = self;
So, all I need to do is adding that one line and it works now. okay, so silly of me for not noticing such a basic thing. But thanks for your helps :D
I am trying to create AVAudioplayer programatically.The audio player successfully playing.But i have some issues.I am displaying 12 audio items in UITableview.If i click first item that should navigate audio player view controller.And i click the play button the song will play.If i click back button the song play continuously.But if i click again same item the Audio view controller the view will display initial state like progress bar should not move and current time and song duration are empty.but song play continuously.
And another issue is there. If i click first item that corresponding song will play.I should not click any pass button.i click back button and click second item.if i click second item the audio view controller will display.I click play button the song display.In background first song play and second song also play.This is my second issue.how to solve these two issues.please help me any body.

I think the problem is here
audioPlayer = [[AVAudioPlayer alloc] initWithData:objectData error:&err];
Each time you are creating the audioPlayer object. So my suggestion is check for audioPlayer before creating the object like this
if(audioPlayer)
{
audioPlayer.delegate=nil;
audioPlayer=nil;
}
Then create the object.
In short what's happening is the following:
you click on the table cell
you create an audio player view controller
You play the audio - your audio player itself is retained for some reason (Unclear why - are you using ARC?)
You click the back button - the Audio player view controller is released
you click the table cell again - and create a new audio player view controller with it's own player!
Basically - if you want the previous song continue playing even when your exiting the Audio player view controller - and to have only a single player for the audio - I would hold it in a singleton class that will manage the player , or as a property of the app delegate.
This way - when you enter the Audio Player view controller - It will check the following:
If a player doesn't exist - create it and assign it the item - ready to play
If a player exists but it's the same item - just update the controls to show it's current playing status.
If a player exists but it's another item - either don't update the controls - and when the user hits play - replace the item in the player and start updating the controls - or stop the song as you display the Audio player view controller. (Up to you - I don't know the design of your app obviously)
In working with AVAudioPlayer, I use a property to keep up with the player. Based on looking at your code it isn't clear to me that you are keeping the player around, or that you aren't instantiating a new instance every time. Based on your description, it sounds like you ARE instantiating a new instance - don't think you want that.
So in your .h file, something like this:
#property (nonatomic, strong) AVAudioPlayer *myAVAudioPlayer;
and then the corresponding #synthesize in your .m file.
When you want to move from one song to the next, simply stop playing current - then reload a new URL using an init for your self.myAVAudioPlayer property. You MUST then call the prepareToPlay method again for the AVAudioPlayer option.
You probably will make it easier on yourself by not managing the variables regarding playing or not (it looked like you were doing that from your post). Use your property and check by accessing the setter/getter for the property for state of the player:
if(!self.myAVAudioPlayer)
{
// allocate and initialize using the code you have
[self.myAVAudioPlayer prepareToPlay];
} else
if ([self.myAVAudioPlayer isPlaying])
{
//do whatever you need for isPlaying - looks like pause
} else
if (![self.myAVAudioPlayer isPlaying])
{
// do whatever you need to do if the player isn't playing when the button is pressed
// at this point you will likely just re-init with a new URL and reset other items
// don't forget to call -prepareToPlay again
}
Here is a link to another approach which takes advantage of AVPlayerItem --> click https://stackoverflow.com/a/22254588/3563814
just wondering how to make a button "START" that when pressed triggers a function and the text changes to "STOP". then when pressed again the function will stop and the text changes back to "START"
Ive got the button already that starts the function. and i can handle changing the title, just not sure on what to use to make the 1 button have 2 functions
Add the IBAction method like:
- (IBAction)buttonTapped:(id)sender
{
UIButton *btn = (UIbutton *)sender;
NSString *title=btn.titleLabel.text;
if ([title isEqualToString:#"Start"])
{
//Start
}else
{
//Stop
}
}
Please try this:
- (IBAction) buttonAction:(id)sender
{
if([[(UIButton *)sender currentTitle]isEqualToString:#"START"])
{
[actionButton setTitle:#"STOP" forState:UIControlStateNormal];
//start the action here and change the button text to STOP
}
else if([[(UIButton *)sender currentTitle]isEqualToString:#"STOP"])
{
[actionButton setTitle:#"START" forState:UIControlStateNormal];
//stop the action here and change the button text to START
}
}
you have at least two options here:
Check for the title of your button and depending on the value call an action or the other.
Create two different buttons, each one with his action and show/hide them.
