Im making a button play sound, like a button sound effect for example in jely car 3 when you press like a new game button it would have a sound effect like "boop." I have done that but there is heaps of lag on the ios simulator which means there will be more on the iphone HELP TKS!

You might want to check out the Audio 101 tutorial on Ray Wenderlich's page. http://www.raywenderlich.com/259/audio-101-for-iphone-developers-playing-audio-programmatically

The first code sample shows how to play a sound. Essentially the code is this:

NSString *soundFile = [[NSBundle mainBundle] pathForResource:@"MySound" ofType:@"caf"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFile];
AudioServicesCreateSystemSoundID((CFURLRef)soundFileURL, &_MySound);
AudioServicesPlaySystemSound(_MySound);

This is the simplest way to play a sound. As Ray mentions in his tutorial, there are other options such as OpenAL that promise lower latency.
