    <p>I would suggest you create a global player object. Because right now, each time you push this view on the navigation controller you create a new one. This also means that you do not have any reference to the previous player (and can not stop it). So: declare the AVAudioPlayer one step higher (in the tableview). Now, when you select a row in it, assign it to a property of this new view (the one you linked).</p> <p>Do you work with storyboard? Then you have to implement the method <code>prepareForSegue:</code>. Give your segue on the storyboard an identifier (like <code>showPlayer</code> and check for that with <code>if (segue.identifier isEqualToString:@"showPlayer")</code>).</p> <p>Now in your <code>viewDidLoad</code> do a check if <code>audioPlayer</code> is nil. If you </p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; if (audioPlayer == nil) { // your init (audioplayer =[[AVAudioPlayer ... } else { if (audioPlayer.isPlaying) { // i.e. pause the player or do other stuff } } } </code></pre> <p>Hope this helps you. </p> <p><strong>Also</strong>: Do not post images of code. Just insert the code in your response or post it to a site like pastebin.com and link that page in your question. This makes it easier for others to respond and make suggestions how to alter your code.</p> <p><strong>In response to your comment</strong>: The relevant stuff should be: <em>In AudioTableViewController.h</em>:</p> <pre><code>@property (strong, nonatomic) AVAudioPlayer *audioPlayer; </code></pre> <p><em>In AudioTableViewController.m</em>:</p> <pre><code>@synthesize audioPlayer; ... - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. NSUInteger row = indexPath.row; if (row == 0) { self.audio1DetailViewController =[[Audio1DetailViewController alloc] initWithNibName:@"Audio1DetailViewController" bundle:nil]; self.audio1DetailViewController.title = @"Audio"; self.audio1DetailViewController.audioPlayer = self.audioPlayer; [self.navigationController pushViewController:self.audio1DetailViewController animated:YES]; [self.audio1DetailViewController release]; ... </code></pre> <p><em>Audio1DetailViewController.m</em></p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"001Fatiha" ofType:@"MP3"]]; NSError *error; // this is the important part: if we already have something playing, stop it! if (audioPlayer != nil) { [audioPlayer stop]; } // everything else should happen as normal. audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&amp;error]; [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil]; [[AVAudioSession sharedInstance] setActive: YES error: nil]; </code></pre>

    1. COHey @pxldlx,tnx for the answer.I have tried but failed.It sounds just simple what you said,and it makes sense.But I just don't get it,I think. I have declared the AVAudioPlayer in the AudioTableViewController.h from the Audio1DetailViewController.h Then I moved the whole code(not the viewDidLoad part)from the Audio1DetailViewController.m to AudioTableViewController.m I also changed the File'sOwner in the xib file.I can play the song,but not by pressing the play button,but by moving the progress slider. I tried some other things but after 2days,I gave it up and undid all the changes.

    2. CO@iHilas Mh, ok. Without looking at your code I can not really help you that much. Can you edit your original question and add some code (mainly that code that you already posted as an image but this time as text please :) ). Oh and one thing: I don't think you have to change that much. Everything stays the same, but you change the "owner" of your audioPlayer to that superview (in the sense that this controller has a <code>strong</code> property). When you traverse to that new controller you hand the reference audioPlayer to the new controller.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
