Move touch inputs to a TouchController class to move some logic from the iPhoneView class. Only do this for touches on screen since connected trackpads can generate touches as well. The latter ones are of type UITouchTypeIndirectPointer while touches on screen are of type UITouchTypeDirect. They are separated thanks to the preference key UIApplicationSupportsIndirectInputEvents set to YES in Info.plist. Without the preference above, there is no way to distinguish touches from screen from a trackpad.
