I've done a little testing, and although I don't like the method, it's quite easy to do.
Having looked for a private method that may have worked, I couldn't find one. All I found was:
@property BOOL forceFullHeightInLandscape;
- (BOOL)isMinibar;
There is no setter for -isMinibar
, so we can't set that. I guess that it returns a value based on its height. Also, forceFullHeightInLandscape
was set to NO
, however it still didn't adjust its height.
While changing the autoresizingMask
to include UIViewAutoresizingFlexibleHeight
, the view did resize to be smaller, but now it was too small. However, -isMinibar
suddenly returned YES
. So that made me think of just letting the view resize itself, adjusting it to the right height.
So there we go, a method that works, even without private API calls:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
[self.navigationBar performSelector:@selector(sizeToFit) withObject:nil afterDelay:(0.5f * duration)];
}
One thing you'll have to deal with is that the views below the bar won't get adjusted to the smaller bar, so that there will be a gap between the bar and the views below. Easiest way to solve this is to add a container view, just like the case with a UINavigationController
. You'd come up with something like:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
[self performSelector:@selector(resizeViewsForNavigationBar) withObject:nil afterDelay:(0.5f * duration)];
}
- (void)resizeViewsForNavigationBar {
[self.navigationBar sizeToFit];
// Resize containerView accordingly.
CGRect containerViewRect = self.containerView.frame;
containerViewRect.origin.y = CGRectGetMaxY(self.navigationBar.frame);
containerViewRect.size.height = CGRectGetMaxY(self.view.frame) - containerViewRect.origin.y;
self.containerView.frame = containerViewRect;
}
