I made a simple scene that has some GUI buttons in Unity. When you press a button it will set a player preference to 1. I have a button for facebook, twitter and a store. In XCode, when the value hits 1, it switches to a new window with facebook, twitter or the store. My problem is that when I try and retrieve the player preferences in XCode, they always come up as null. To compound my confusion, my code seems to respond to the switch to 1 and it switches to the new window when the value hits 1. Any ideas why it manages to switch to the other window and why I am getting null values?
