VC.view.backgroundColor = [UIColorwhiteColor];

BaseNavigationController *nav = [[BaseNavigationControlleralloc]initWithRootViewController:VC];

CATransition *tran = [CATransitionanimation];

tran.type = kCATransitionPush;

tran.subtype = kCATransitionFromRight;

tran.duration = 0.5;

[[UIApplicationsharedApplication].keyWindow.layeraddAnimation:tran forKey:@"PushFromRight"];
