Change Navbar Button Font

Question

I have this on my AppDelegate.m :

// Change the appearance of back button
UIImage *backButtonImage = [[UIImage imageNamed:@"back"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 20, 0, 0)];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setFont:[UIFont fontWithName:@"Raleway-ExtraLight" size:18]];

build was successful but when it runs on my iPod, it gives me this error message on debugging console :

2013-09-10 16:42:19.581 PushTransition[3599:907] -[_UIBarItemAppearance setFont:]: unrecognized selector sent to instance 0x1cda7100
2013-09-10 16:42:19.586 PushTransition[3599:907] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[_UIBarItemAppearance setFont:]: unrecognized selector sent to instance 0x1cda7100'

libc++abi.dylib: terminate called throwing an exception
(lldb)

I think this caused by this line of code :

[[UIBarButtonItem appearance] setFont:[UIFont fontWithName:@"Raleway-ExtraLight" size:18]];

because when I comment that line, it runs perfectly without error. but the navbar button's font is default font. how to customise it?

thank you

Have you tried something like:

[[UIBarButtonItem appearance] setTitleTextAttributes:
    [NSDictionary dictionaryWithObjectsAndKeys:
        [UIFont fontWithName:@"AmericanTypewriter" size:20.0],
        UITextAttributeFont,
        nil]
    forState:UIControlStateNormal];

This also allows you to edit other attributes such as shadow etc. From this great tutorial

This has been updated with IOS7: `[[UIBarButtonItem appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"AmericanTypewriter" size:20.0], NSFontAttributeName, nil] forState:UIControlStateNormal];` – Joshua Hart Nov 01 '15 at 16:31

Try this

Available UITextAttributes (just add them to the NSDictionary):

UITextAttributeFont: Change font with a UIFont
UITextAttributeTextColor: Change color with a UIColor
UITextAttributeShadowColor: Change shadow color with a UIColor
UITextAttributeShadowOffset: Change shadow offset with a UIOffset

 [[UIBarButtonItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"Raleway-ExtraLight" size:18.0], UITextAttributeFont,nil] forState:UIControlStateNormal];

From Apple Docs:

Font

The font of the title.

(Deprecated in iOS 3.0. Instead, set the fonts of the UILabel objects assigned to the textLabel and detailTextLabel properties.)

@property(nonatomic, retain) UIFont *font

Doing this however will help:

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