如何使用AVAudioPlayer播放多个音频文件

在我的应用程序中，当我单击图像时，我将在行和列中显示多个图像，我将使用

In my application, I am displaying multiple images in rows and columns when i click on a image i will play corresponding sound using

someName = [someName stringByAppendingFormat:@".mp3"];
[audioPlayer stop];

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/%s", [[NSBundle mainBundle] resourcePath],[someName UTF8String]]];

NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.delegate = self; 

当我单击一张图像时，我会得到特定的图像声音.当我单击另一张图像时，先前的声音将停止并播放与该图像对应的新声音.

When i am clicking on the one image i will get particular image sound. When i click on the another image the previous sound will be stopped and new sound corresponding the image will be played.

我的要求是，当我单击第一幅图像时，声音必须到来，而当我单击第二幅图像时，第一声音不能停止并且都必须播放，而当我单击第三幅时，必须播放三种声音.

My requirement is when i click on the first image the sound must come and when i click on the second image the first sound must not stop and both must play and when i click on the third one the three sounds must play.

请帮帮我
