Scenario 1: For a UIViewController, is it better to (1) create an ivar for a UIView that I access again in 1 or 2 functions outside of loadView? Or, (2) should I just tag it in loadView and then use - (UIView *)viewWithTag:(NSInteger)tag to access it again in the other functions? I'm guessing that option 1 increases the memory by the siz...
