title: Weird problems with program and debugger in xcode
body: <p>Okay, I have a program that I'm trying to test on my iPad. I have it all set up so that the app is able to get on the iPad just fine, but running it on the iPad is a different story.</p>
  
  <p>Now, the thing is, my program was working fine on the debug configuration, but now it won't work on that, either. It's strange, because before I was able to get to a certain part of the program before it crashed, but now it's crashing before that.</p>
  
  <p>The debugger is hardly helping. When I use the debugger window, it will step into one line of code, and then suddenly jump back to another line of code.</p>
  
  <p>I really don't understand what's going on. The crash is now occuring in a root view controller that I have set up, called 'FunctionMachineViewController. Here's the code for when it crashes:</p>
  
  <pre><code>-(IBAction)startOnePlayer:(id)sender
  {
      GameViewController* GameView = [[GameViewController alloc] initWithNibName:nil bundle:nil];
      [GameView isOnePlayer:YES withLevel:startLevelNumber];
      [self presentModalViewController:GameView animated:YES];
  }
  </code></pre>
  
  <p>GameViewController is supposed to initialize just fine, but the debugger shows it as uninitialized. I even tried setting it up in the header file instead, but the problem still happens. Has anyone else come across these problems? Any help would be greatly appreciated!</p>
  
  <p>EDIT: Here's what the console says when it crashes:</p>
