Xcode 4.3 and empty application template

couple things try

1. make sure set main storyboard target storyboard created.

2. in appdelegate.m file

remove following lines
- (bool)application: (uiapplication *)application didfinishlaunchingwithoptions: (nsdictionary *)launchoptions

code:

self.window = [[uiwindow alloc] initwithframe: [[uiscreen mainscreen] bounds]];  // override point customization after application launch.  self.window.backgroundcolor = [uicolor whitecolor];  [self.window makekeyandvisible];

tested on quick project , got rid of error message seeing
