title: Change Something about an App In-Game
body: <p>I'm working on a baseball card game for iOS.  I have completed much of the code, but am now trying to make the method where I will allow the user to select a new pitcher.  I have created a View Controller that will display when the user presses the "Change Pitcher" button, but I'm not sure how I should implement this View Controller, because I want the game to basically pause while the user selects a new pitcher, and then resume with the new pitcher that the user selected.  I initially was going to use a PopOver controller, but now I'm not sure that that's what I'm really looking for.  Does anyone have any suggestions on what I could use to select a new pitcher and then go back to the game such that the game will not have changed when I get back to it?
  Thanks in advance for your help.</p>
