Change font for UIBarButtonItem

Question

I am building an iOS app using Rubymotion and I need to set the font family to a custom font for a button in the navigation bar (UIBarButtonItem). I know I do it like this in Objective-C but how is it done in Ruby?

[buttonItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"Helvetica-Bold" size:26.0], UITextAttributeFont,nil] forState:UIControlStateNormal];

Thankful for all help!

just curious. Why Rubymotion instead of Xcode? because of the Objective-C learning curve? — Raptor, Nov 19 '12 at 08:51
I know Ruby very good (Rails developer) and I see no reason to use Objective-C since the outcome from both Rubymotion and Objective-C is exactly the same. — Jonathan Clark, Nov 19 '12 at 09:01
just discussion: Rubymotion can't build Interface easily, right? (need to build via 100% codes only, i.e. no drag & drop) — Raptor, Nov 19 '12 at 09:25
No, you can use both Storyboards and Nib files. They are compiled automatically with Rubymotion. — Jonathan Clark, Nov 19 '12 at 09:52

I think this will do it. I don't have my Mac handy to test this out so give it a shot and let us know how it goes.

buttonItem.setTitleTextAttributes({UITextAttributeFont => UIFont.fontWithName("Helvetica-Bold", size:26.0)}, forState:UIControlStateNormal)

In your AppDelegate use something like this

NSDictionary *itemTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                    [UIColor whiteColor],NSForegroundColorAttributeName,
                                    [UIColor whiteColor],NSBackgroundColorAttributeName,
                                    [UIFont fontWithName:@"Ubuntu-Regular" size:18],NSFontAttributeName,
                                    nil];

[[UIBarButtonItem appearance] setTitleTextAttributes:itemTextAttributes forState:UIControlStateNormal];
