Change font of back button on UINavigationController

I'm trying to change the font color of the text on my back button in my UINavigationControllerBar:

[[UIBarButtonItem appearance] setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

I get this error:

[_UIBarItemAppearance setTitleColor:forState:]: unrecognized selector sent to instance 0x69aeb70'

Use this instead, default function available in iOS 5:

UIBarButtonItem *backbutton = [[UIBarButtonItem alloc] initWithTitle:@"back" style:UIBarButtonItemStyleBordered target:nil action:nil];

[backbutton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
    [UIColor blackColor],UITextAttributeTextColor,
    [UIFont fontWithName:TEXTFONT size:16.0f],UITextAttributeFont,nil]
    forState:UIControlStateNormal];

Solution in Swift 4:

UIBarButtonItem.appearance().setTitleTextAttributes(
[
    NSAttributedStringKey.font: UIFont(name: "MyriadPro-SemiboldCond", size: 16)!,
    NSAttributedStringKey.foregroundColor: UIColor.white
], for: .normal)

Add this in AppDelegate and it'll be applied to all buttons in the app.

And the beautiful solution, iOS7+ (because of attribute names):

NSShadow *shadow = [NSShadow new];
[shadow setShadowColor: [UIColor colorWithWhite:0.0f alpha:0.750f]];
[shadow setShadowOffset: CGSizeMake(0.0f, 1.0f)];

[[UIBarButtonItem appearance] setTitleTextAttributes:@{
        NSFontAttributeName: [UIFont systemFontOfSize:24],
        NSForegroundColorAttributeName: [UIColor colorWithWhite:0.2 alpha:1.0],
        NSShadowAttributeName: shadow,
} forState:UIControlStateNormal];

[[UIBarButtonItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                     [UIFont fontWithName:kDefaultFont size:16.0f],UITextAttributeFont,
                                                     nil] forState:UIControlStateNormal];

NSMutableDictionary *attributes = [NSMutableDictionary dictionary];
[attributes setValue:[UIColor colorWithRed:(163.0f/255.0f) green:(0.0f) blue:(0.0f) alpha:1.0f] forKey:UITextAttributeTextColor];
[attributes setValue:[UIColor clearColor] forKey:UITextAttributeTextShadowColor];
[attributes setValue:[NSValue valueWithUIOffset:UIOffsetMake(0.0, 0.0)] forKey:UITextAttributeTextShadowOffset];
[[UIBarButtonItem appearance] setTitleTextAttributes:attributes forState:UIControlStateNormal];

seems to work!
