cambiar la fuente del botón atrás en uinavigationcontroller

Estoy tratando de cambiar el color de la fuente del texto en mi botón atrás en mi UINavigationControllerBar

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

Me da este error: [_UIBarItemAppearance setTitleColor:forState:]: selector no reconocido enviado a la instancia 0x69aeb70 '

Alguna ayuda? ¡Gracias!

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];

Parece funcionar!

Y la hermosa solución, iOS7+ (debido a los nombres de atributos):

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];

Solución en Swift 4:

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

Agregue esto en AppDelegate y se aplicará a todos los botones de la aplicación.

Utilice esta función en su lugar, por defecto disponible en 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];
