How can I make a UIToolbar from a UINavigationController taller?

Question

I have a UINavigationController with a UINavigationBar at the top of the screen and a UIToolbar at the bottom. I want to make the toolbar a bit taller. Here's my code:

CGRect toolbarFrame = self.navigationController.toolbar.frame;
toolbarFrame.size.height += 20;
toolbarFrame.origin.y -= 20;
self.navigationController.toolbar.frame = toolbarFrame;

[self setToolbarItems:@[myButton]];
self.navigationController.toolbarHidden = NO;

This seems like it should work and doesn't generate any errors/warnings, but the size of the toolbar stays at the defaults.

Is there a way to change the size of a UINavigationController's UIToolbar, or should I just make a custom UIToolbar for this?

Answer 1

I've tried your code and just adjust your code's sequence. It will work:

[self setToolbarItems:@[myButton]];
self.navigationController.toolbarHidden = NO;

CGRect toolbarFrame = self.navigationController.toolbar.frame;
toolbarFrame.size.height += 20;
toolbarFrame.origin.y -= 20;
self.navigationController.toolbar.frame = toolbarFrame;

I think this is because setToolbarItems will adjust the appearance of your tool bar. So you need firstly do other init-related things. Then adjust its appearance(such change its frame.)
