From Ray Wenderlich:

// 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]]; 

Or if you prefer with the object literal style:

[[UINavigationBar appearance] setTitleTextAttributes:@{     UITextAttributeTextColor: [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],     UITextAttributeTextShadowColor: [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],     UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],     UITextAttributeFont: [UIFont fontWithName:@"Arial-Bold" size:0.0], }]; 

Edit for iOS 7 and following

UITextAttributes are deprecate as iOS 7 you can use the following :

NSShadow *shadow = [[NSShadow alloc] init]; shadow.shadowColor = [UIColor colorWithWhite:.0f alpha:1.f]; shadow.shadowOffset = CGSizeMake(0, -1);  [[UINavigationBar appearance] setTitleTextAttributes:@{      NSForegroundColorAttributeName: [UIColor whiteColor],      NSShadowAttributeName: shadow,      NSFontAttributeName: [UIFont fontWithName:@"Arial-Bold" size:15.0f]      }]; 

Answer 2

For deployment targets greater than or equal to iOS 6, you should use NSShadow instead:

NSShadow * shadow = [[NSShadow alloc] init]; shadow.shadowColor = [UIColor lightGrayColor]; shadow.shadowOffset = CGSizeMake(0, -2);  NSDictionary * navBarTitleTextAttributes = @{ NSForegroundColorAttributeName : [UIColor redColor],    NSShadowAttributeName          : shadow,    NSFontAttributeName            : [UIFont systemFontOfSize:14] };  [[UINavigationBar appearance] setTitleTextAttributes:navBarTitleTextAttributes];
