  Hi,
  
  I have been making buttons and making them take you to a different view once their tapped. I am currently using IBActions and defining them as View1 setHidden: Yes and View2 setHidden No, which just causes the other view to appear. This gets really tiring though when you need a different view to disappear (what I'm trying to say you can't just simply copy and paste). Is there a way of linking the buttons together into one code, like for example say that I have 50 different views, and all of them have one button for the main menu. I would have to make 50 IBActions, but I am looking for a way to say something like 'take user to "MainView" '. You would probably have to do it with an 'if', but I have no idea how to start this problem at all.
  
  Thanks in advance,

  I think you need to brush up on what View Controllers are for and how you switch between views. It sounds like you've got all views active at once and you hide the ones you don't want to see? That is completely the wrong approach.

  Hi,
  
  Thanks for your reply. I know how to use the navigation controllers and view controllers though. So should I just make a view, link it to a view controller, but instead of the 'didselectrowatindexpath' should I say something like 'didselectbutton'? I would have to switch everything to something else. And its more of a game, so I can't really use the navigation controller with table cells.

  Hi,
  
  I am bumping my thread so it gets noticed again, because right now its on page 3, and is not likely to get any more attention.
  
  I have tried to solve my problem (the one stated at the very top), but I couldn't figure it out yet. I tried implementing the ModalView, but I don't want it to be a ModalView, because I need it to be another 'main' screen.

  Yeah, say you have 2 screens (saying screen not to confuse with UIView). Screen 1 = menu, Screen 2 = game.
  
  Screen 1 and 2 (GameScreen) would extend UIViewController. When someone hits your button you call your IBAction and present the view modally. You can change the animation for entry but I'll leave you to look at the docs for that (or you can set to NO to make it instantly show):
  
  

  
  - (IBAction)didHitPlay {
      GameScreen* gameScreen = [[GameScreen alloc] init];
      [self presentModelViewController:gameScreen animated:NO];
      [gameScreen release];
  }

  Thanks for your reply. I tried implementing that, and I got everything to work, except that when I build and run I get an error that I need to declare the 'GameScreen'. I made an xib with the name of GameScreen though. And the window is linked to the GameScreenViewController. Any ideas?
  
  Thanks

  Yeah, I made GameScreen up. I should have been clearer, you need to replace this with the classname of your second UIViewController (which you can add a nib for when you create if you like).
