I have an app where I play an audio-file on launch in the View Controller. I also have a button that switches to my second view. My problem is that the audio continues to play even after I have switched view. Here's my code for ViewController.m:
#import <AVFoundation/AVFoundation.h>
#interface ViewController ()
#end
#implementation ViewController
//When I go to this view, I want the audio to stop
- (IBAction)SwitchView:(id)sender {
SecondViewController *second = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
[self presentViewController:second animated:YES completion:NULL];
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"home_sound"
ofType:#"mp3"]];
NSError *error;
homeaudioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
} else {
homeaudioPlayer.delegate = self;
[homeaudioPlayer setNumberOfLoops: -1];
[homeaudioPlayer prepareToPlay];
}
[homeaudioPlayer play];
}
#end
How can I do this?
Thanks.
update your SwitchView code-
- (IBAction)SwitchView:(id)sender {
[homeaudioPlayer stop];
SecondViewController *second = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
[self presentViewController:second animated:YES completion:NULL];
}
Simply add [homeaudioPlayer stop]; to your switchView method. This should stop all sound that the player is playing.

I've been pulling out my hair past three days to fix this problem. I've checked lots of sample codes, read lots of tutorials, and googled and checked lots and lots of questions and answers on stackoverflow, but I still cannot fix the problem. There are several similar questions like this or this but they don't have any solutions either.
So a little bit about my project:
I have a NIKMasterViewController and a NIKDetailViewController. In the first one I have a list of audio files in a table view; selecting a row, it navigates to the NIKDetailViewController where the user can see some info about the file and play the audio file.
I've defined an AVAudioPlayer property in the NIKMasterViewController and have set it like this:
NIKMasterViewController.h:
#property (nonatomic, strong) AVAudioPlayer *audioPlayer;
NIKMasterViewController.m:
#synthesize audioPlayer;
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"showDetail"])
{
NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];
NIKDetailViewController *detailViewController = (NIKDetailViewController *) segue.destinationViewController;
[detailViewController setAudioPlayer:audioPlayer];
[detailViewController setFeedEntry:[[[self feedParser] feedItems] objectAtIndex:indexPath.row]];
} else {
NSLog(#"Segue Identifier: %#", segue.identifier);
}
}
And that's all about the AVAudioPlayer in NIKMasterViewController. Now in my NIKDetailViewController I have another property of AVAudioPlayer:
NIKDetailViewController.h:
#property (nonatomic, strong) AVAudioPlayer *audioPlayer;
Now in my .m file I have a method called streamAudio which is called in viewDidLoad to prepare the audio playback, and I have an if condition asking to check if the audioPlayer is nill and if not, if the audioPlayer.isPlaying is true so that it stops the player, but it's never called, and when i navigate back to the Master VC to tap on another row to play another file, the second file starts playing while the first file is being played and everything gets mixed up.
Any help will be truly appreciated, since I'm almost about to stop programming after being unable to fix this issue after hours and days!

NOTE: I have tried setting the property in the Detail VC as weak but then, I get a warning, and the property is release before I can play the file.
So... I could finally fix this problem by creating a singleton of the audioplayer. This is how:
First of all, I removed all the code related to the audioPlayer from my NIKMasterViewController class, that includes the audioPlayer declaration and setting it in prepareForSegue.
I created a new class called NIKAudioPlayer.
In NIKAudioPlayer.h:
#import <Foundation/Foundation.h>
#import <AVFoundation/AVFoundation.h>
#interface NIKAudioPlayer : NSObject <AVAudioPlayerDelegate>
{
AVAudioPlayer *currentPlayer;
}
#property (nonatomic, strong) AVAudioPlayer *currentPlayer;
+(NIKAudioPlayer *) sharedPlayer;
-(void)playURL:(NSURL*)url;
#end
In NIKAudioPlayer.m:
#import "NIKAudioPlayer.h"
#implementation NIKAudioPlayer
#synthesize currentPlayer;
+(NIKAudioPlayer *) sharedPlayer
{
static NIKAudioPlayer* sharedPlayer;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedPlayer = [[NIKAudioPlayer alloc] init];
});
return sharedPlayer;
}
-(void)playURL:(NSURL*)url
{
[currentPlayer stop];
currentPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[currentPlayer prepareToPlay];
}
#end
Now in everywhere else in the code (in my case in NIKDetailViewController) whenever I need to play an audio file, I call the sharedPlayer from NIKAudioPlayer:
[[NIKPlayer sharedPlayer] playURL:audioURL];
[[NIKPlayer sharedPlayer].currentPlayer prepareToPlay];
To put in a nutshell, replace all audioPlayers in NIKDetailViewController with [NIKPlayer sharedPlayer].currentPlayer, or even cast it and use it everywhere:
audioPlayer = [NIKPlayer sharedPlayer].currentPlayer
How could I get the audio from phone and get it to share via email?
Will it available?
Can we share it simply like music at application?
Your question could have been better, you should show what you've tried, your specific problem, your actual results and your expected result.
Having said that, this sounded like a nice challenge.. so the answer follows.
I'm not sure if you wanted to get the music from the iPod or the app bundle so I implemented the iPod version as (in my opinion), it's more complex.

I have 3 buttons. In the 'Supporting Files' folder I have an array of strings with the name of the sound files I want to play, named 'Sound.plist', and in the 'Supporting Files' folder I have a folder named 'Sounds', which contains the sound files.
All of my buttons play the same sound, even when I delete the .plist file. It seems to always play the sound that is first in the 'Sounds' folder. Can someone please provide some insight, I feel like I have tried everything. Thanks!
EDITED

You never initialized your view controller.
Somewhere before you do
[window addSubview:viewController.view];
You need to do
self.viewController = [[ViewController alloc] init];
I see that you declared the property as an IBOutlet.. is it actually hooked up to something in Interface Builder?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

Copy that function and just delete this one - (void)applicationDidFinishLaunching:(UIApplication *)application completely.
You should also consider converting your project to use ARC. It will remove the need to retain/release/autorelease statements.
You have two targets - are all your resources included in the target that you're building?
