Playing an audio file in the mainBundle through an NSDictionary

Question

I have an audio file audio1.caf in my mainBundle.
In the mainViewController I want to use an NSDictionary with audio1.caf being the object for the key audio1Key
In my detailViewController I want to have the user tap a button and the audio plays.
This sounds like a very simple  thing but search as I might I can't seem to find the answer.
Here is the code for my dictionary in the mainViewController
if ([vc isKindOfClass:[detailViewController class]])
        detailViewController*lcVC =(detailViewController*)vc;
NSMutableDictionary *mydDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                       @"audio1.caf",@"firstAudioKey",nil];
lcVC.myDictionary = myDictionary;  
    [self.navigationController pushViewController:vc animated:YES];
Then in my detailViewController I use
-(IBAction)buttonPressedid)sender {
    NSError *error = nil;
    NSString *firstAudio = [myDictionary objectForKey:@"firstAudioKey"];
    NSURL *url = [NSURL fileURLWithPath:firstAudio];
    theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
    theAudio.delegate =self;
    theAudio.volume = 1.0;
    theAudio.numberOfLoops = 0;
     NSLog (@"%@",url);
    if ([theAudio isPlaying]){[theAudio pause]; }else{[theAudio play];}}
So I know things are getting passed by the dictionary ok because other things are showing up (text, and other audio) stored in the documents directory.
However this shows that the url path is audio1.caf --file://localhost/ So I am gettin the name of the objectForKey but not the whole path.  I think I need to look in the mainBundle and get the path to the file but I cannot seem to be able to figure this out.  I have looked all over the internet for a discussion, or tutorial. but no luck.  Can someone point out where I'm going wrong or suggest where to look.  Thanks

I finally figured this out DUH!  Here's my code if anyone wants to look at it and tell me if I'm doing something wrong.
-(IBAction)buttonPressed2:(id)sender {
    NSError *error = nil;
    NSString *someAudio = [[NSBundle mainBundle]bundlePath];
    NSString *audioPath = [someAudio stringByAppendingPathComponent:[myDictionary objectForKey:@"firstAudioKey"]];
    NSURL *url = [NSURL fileURLWithPath:audioPath];
    theAudio7 = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
    theAudio7.delegate =self;
    theAudio7.volume = 10.0;
    theAudio7.numberOfLoops = 0;
    NSLog (@"%@",firstAudioKey);
    if ([theAudio7 isPlaying]){[theAudio7 pause]; }else{[theAudio7 play];}}
Thanks to everyone.
