iOS - Globally change navigation bar title color using appearance? - ios

Question

This crashes the app:
[[UINavigationBar appearance] setTitleColor:[UIColor darkGrayColor] forState:UIControlStateNormal];
Is there a way to do this using appearance?

Answer 1

This worked:
NSDictionary *textTitleOptions = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor darkGrayColor], UITextAttributeTextColor, [UIColor whiteColor], UITextAttributeTextShadowColor, nil];
[[UINavigationBar appearance] setTitleTextAttributes:textTitleOptions];

Answer 2

Here's an example of how to do this in Swift:
UINavigationBar.appearance().titleTextAttributes =
[NSFontAttributeName:UIFont(name:"Exo2-Bold", size: 18) as! AnyObject,
NSForegroundColorAttributeName:UIColor.whiteColor()]

Answer 3

That crashes the app before UINavigationBar doesn't have a title or state... Those are UIButton methods
You need
[[UINavigationBar appearance] setTintColor:[UIColor darkGrayColor]];

Answer 4

The #RyJ answer is great and worked for me. Thought I'd chip in that there's a good tutorial on this in Ray Wenderlich's site, titled (excuse the pun):
User Interface Customization in iOS 6
See the section Customizing UINavigationBar
Here's the code snippet for the navigation bar title, to change globally:
// Customize the title text for *all* UINavigationBars
[[UINavigationBar appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],
UITextAttributeTextColor,
[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],
UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Arial-Bold" size:0.0],
UITextAttributeFont,
nil]];
One other minor point is that it seems there's a default shadow on the title bar, so to get rid of it, you can't just remove the attribute. Instead you have to set a shadow offset:
UITextAttributeTextShadowOffset : [NSValue valueWithUIOffset:UIOffsetMake(0, 0)]

Answer 5

for iOS 15
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = <PREFERRED BACKGROUND COLOR>
appearance.titleTextAttributes = [.foregroundColor : <PREFERRED TITLE COLOR>]
navigationBar.tintColor = <PREFERED TINT COLOR> //for bar buttons
navigationBar.standardAppearance = appearance;
navigationBar.scrollEdgeAppearance = navigationBar.standardAppearance

Answer 6

I used following code to change the title bar's color.
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor blackColor];
shadow.shadowOffset = CGSizeMake(1, 0);
NSDictionary *titleTextAttributes = #{NSForegroundColorAttributeName:[UIColor whiteColor],
NSShadowAttributeName:shadow};
[[UINavigationBar appearance] setTitleTextAttributes:titleTextAttributes];

Answer 7

Using modern syntax and code that actually runs, this is how to globally style your UINavigationBar title text:
NSShadow *navigationBarTitleShadow = [[NSShadow alloc] init];
navigationBarTitleShadow.shadowColor = [UIColor colorWithWhite:0.5
alpha:0.5];
navigationBarTitleShadow.shadowOffset = CGSizeMake(2.0, 2.0);
[[UINavigationBar appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName : [UIColor blackColor],
NSFontAttributeName : [UIFont fontWithName:#"Arial-BoldMT"
size:30.0],
NSShadowAttributeName : navigationBarTitleShadow }];
Note: NSShadow's shadowBlurRadius property is not respected.
Note: Shadows are so iOS 6. Don't ever use them.
