您可以使用滑块提供了由CCControlExtension并使用回调方法来改变你的声音的音量为解释在这里.

这里有一个"伪"代码,向您展示如何实现此目的:

// Create your audio engine
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"music.mp3"];

// Create the slider
CCControlSlider *slider = [CCControlSlider sliderWithBackgroundFile:@"sliderTrack.png" progressFile:@"sliderProgress.png" thumbFile:@"sliderThumb.png"];
slider.minimumValue = 0.0f; // Sets the min value of range
slider.maximumValue = 1.0f; // Sets the max value of range

// When the value of the slider will change, the given selector will be call
[slider addTarget:self action:@selector(valueChanged:) forControlEvents:CCControlEventValueChanged];

[self addChild:slider]; 

//...

- (void)valueChanged:(CCControlSlider *)sender
{
   // Change volume of your sounds
   [[SimpleAudioEngine sharedEngine] setEffectsVolume:sender.value];
   [[SimpleAudioEngine sharedEngine] setBackgroundMusicVolume:sender.value];
}

我希望它能帮到你.
