Modal status bar and navigation bar text colors from UIActivityViewControllers in iOS 7

Question

When I\'m using a UIActivityViewController, after the user chooses an activity (such as Mail or Message), I can not change the text color for the status bar nor

Answer 1

I believe the code to change the navigation bar color is this:

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

This is for changing the colours of the navigation bar buttons in iOS 7, if you might need it:

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

And this is the code if you want to change the colours of the buttons in iOS 6:

[[UIBarButtonItem appearance] setTintColor:[UIColor redColor]];

This code is also for iOS 8+ to change the bar button text color for UIActivityViewController activities (like sharing via Messages or Mail Composer).
