Ios – UINavigationBar editable title

I dunno if you got this figured out. But for others that might have this problem...

What you need to do is to specify the class in your XIB to your class name (in this case MyNavigationBar.

Check session 123 in WWDC 2011.

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;
}
