Question

I want to play multiple MP3 files, in sequence (one after the other) , using AVAudioPlayer. I tried it, and it stops after playing the first MP3. However, if I go into deb

I've implemented a class to handle this.

To use just do something like this:

[looper playAudioFiles:[NSArray arrayWithObjects:
    @"add.mp3",
    [NSString stringWithFormat:@"%d.mp3", numeral1.tag],
    @"and.mp3",
    [NSString stringWithFormat:@"%d.mp3", numeral2.tag],
    nil
]];

Looper.m

#import "Looper.h"
@implementation Looper
@synthesize player, fileNameQueue;

- (id)initWithFileNameQueue:(NSArray*)queue {
    if ((self = [super init])) {
        self.fileNameQueue = queue;
        index = 0;
        [self play:index];
    }
    return self;
}

- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
    if (index < fileNameQueue.count) {
        [self play:index];
    } else {
        //reached end of queue
    }
}

- (void)play:(int)i {
    self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:[fileNameQueue objectAtIndex:i] ofType:nil]] error:nil];
    [player release];
    player.delegate = self;
    [player prepareToPlay];
    [player play];    
    index++;
}

- (void)stop {
    if (self.player.playing) [player stop];
}

- (void)dealloc {
    self.fileNameQueue = nil;
    self.player = nil;        
    [super dealloc];
}

@end
