How to create multiple thread

Question

Hi I want to create multiple thread in my game. One thread is for timer and other for touch event. Because when i am running this game on iphone timer conflict the touch events so touch event will not be detected. Its working smooth on iphone simulator but on iphone or on itouch its became very slow. So i m using thread for touch and timer. When i give [NSThread sleepForTimeInterval:0.01] call to timer it sleep all threads means touch also get stop. I want to stop perticular thread only.

This is my code in touchesBegan -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

 BOOL Done = NO;

 while (!Done)
 {

  NSAutoreleasePool *loopPool = [[NSAutoreleasePool alloc] init];
  [NSThread sleepForTimeInterval:0.01];
  [self performSelectorOnMainThread:@selector(callTapCode) withObject:tapView waitUntilDone:YES];

  //performSelectorOnMainThread:@selector(callTapCode) withObject:nil waitUntilDone:YES];

  [loopPool release];
  Done=YES;
 }

 [pool drain];

}

please its very urgent help me out :(

If you are trying to create a timer, you should probably just use NSTimer, because that's simpler and more efficient than creating a thread just to send a "go" event every so often.

edit: As is, you aren't creating a second you are merely stalling the main thread by calling [NSThread sleepForTimeInterval:0.01] in a loop. This means your main thread is no longer running the event loop which can cause all kinds of things to no longer work.
