Play multiple music with AVAudioPlayer - iphone

Question

I am trying to play a 2 musics they should play after each other with loop option ,
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSString * music = [[NSBundle mainBundle] pathForResource:#"music" ofType:#"wav"];
myMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:music] error:NULL];
myMusic.delegate = self;
[myMusic play];
}
and play second music :
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
NSString * music = [[NSBundle mainBundle] pathForResource:#"music2" ofType:#"wav"];
myMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:music] error:NULL];
myMusic.delegate = self;
[myMusic play];
NSLog(#"MUSIC FINISH");
}
now the problem is how can I play previous music ?

Answer 1

Try this
ViewController.h
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#interface ViewController : UIViewController<AVAudioPlayerDelegate>
{
AVAudioPlayer *player;
int nIndex;
NSArray *arrPlayList;
}
#end
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
arrPlayList =[[NSArray alloc]initWithObjects:#"music1.wav",#"music2.wav",#"music3.wav", nil];
nIndex =[arrPlayList count]-1;
[self playSound:nIndex];
}
-(void)playSound:(int )index
{
NSString *path = [[NSBundle mainBundle] bundlePath];
NSString *strFilePath = [path stringByAppendingPathComponent:[arrPlayList objectAtIndex:index]];
NSURL *filePath = [NSURL fileURLWithPath:strFilePath];
player= [[AVAudioPlayer alloc] initWithContentsOfURL:filePath error:nil];
player.delegate=self;
[player play];
}
#pragma mark - AVFoundation Delegate Methods
-(void)audioPlayerDidFinishPlaying: (AVAudioPlayer *)player successfully:(BOOL)flag
{
NSLog(#"MUSIC FINISH");
if (nIndex==0) {
return;
}
nIndex--;
[self playSound:nIndex];
}
-(void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error
{
NSLog(#"Decode Error occurred");
}
