ios7 - iOS 7 UIBarButton back button arrow color

Question

I'm trying to change the back button arrow

I'm currently using the following to control the text size as well as the text color on the back button:

[[UIBarButtonItem appearance] setTitleTextAttributes:
  [NSDictionary dictionaryWithObjectsAndKeys:
    [UIColor whiteColor], UITextAttributeTextColor,
    [UIFont boldSystemFontOfSize:16.0f], UITextAttributeFont,
    [UIColor darkGrayColor], UITextAttributeTextShadowColor,
    [NSValue valueWithCGSize:CGSizeMake(0.0, -1.0)], UITextAttributeTextShadowOffset,
  nil] forState:UIControlStateNormal];

but if I want to change only the arrow's color for the back button, what should i do?

Answer 1

To change the back button chevron color for a specific navigation controller*:

self.navigationController.navigationBar.tintColor = [UIColor whiteColor];

*If you are using an app with more than 1 navigation controller, and you want this chevron color to apply to each, you may want to use the appearance proxy to set the back button chevron for every navigation controller, as follows:

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

And for good measure, in swift (thanks to Jay Mayu in the comments):

UINavigationBar.appearance().tintColor = UIColor.whiteColor()
