IOS 4.3 hide status bar permanently
Try this:
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];From Apple Class Reference:
setStatusBarHidden:withAnimation:
Hides or shows the status bar, optionally animating the transition. - (void)setStatusBarHidden:(BOOL)hidden withAnimation:(UIStatusBarAnimation)animation Parameters
hidden YES to hide the status bar, NO to show the status bar.
animation A constant that indicates whether there should be an animation and, if one is requested, whether it should fade the status bar in or out or whether it should slide the status bar in or out.
But how about [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
See the UIApplication reference.
