-(Bool) Application :( uiapplication *) Application didfinishlaunchingwitexceptions :( nsdictionary *) launchoptions {If ([[uidevice currentdevice]. systemversion floatvalue] <6.0) {[[uiapplication sharedapplication] setstatusbarorientation: uiinterfaceorientationlandscapeleft animated: No];} self. window = [[uiwindow alloc] initwithframe: [uiscreen mainscreen]. bounds]; If (nil = self. bootviewcontroller) {self. bootviewcontroller = [[bootviewcontroller alloc] init];} // sets the display method. Other Sub-control views to be added are the same as if ([uidevice currentdevice]. systemversion floatvalue] <6.0) {[self. window addsubview: Self. bootviewcontroller. view];} else {[self. window setrootviewcontroller: Self. bootviewcontroller];} [self. window makekeyandvisible];}
