Challenge 3 : Now we want to change the color of the text of our navigation bar buttons to white.

What's wrong with the third UINavigationBar appearance line?

import "AppDelegate.h"

@implementation AppDelegate

  • (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Customize the nav bar UIImage *backgroundImage = [UIImage imageNamed:@"navBarBackground"]; [[UINavigationBar appearance] setBarTintColor:[UIColor redColor]]; [[UINavigationBar appearance] setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault]; [[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,nil]];

    return YES; }

@end

Replace it with this

[[UINavigationBar appearance]setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor whiteColor]}];

UITextAttributeTextColor is deprecated.

Hi, the posted answer above did not work. I am repasting the original code with error to make it clearer. In the original code, the third line is not working.

  • (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Customize the nav bar UIImage *backgroundImage = [UIImage imageNamed:@"navBarBackground"]; [[UINavigationBar appearance] setBarTintColor:[UIColor redColor]]; [[UINavigationBar appearance] setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault]; [[UINavigationBar appearance] setTextTitleAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,nil]];

    return YES; }

Sorry, I didn't read the question properly.

To set the Nav Bar buttons to White use the following code.

[[UINavigationBar appearance]setTintColor:[UIColor whiteColor]];

You don't need to set the TitleTextAttributes for the Challenge
