Answer 1

Rather than sub-classing from UIActivityViewController, we can change the tintColor of the navigation bar upon presenting it and revert it upon completion in the completionHandler. For example:

UIColor *normalColor = [[UINavigationBar appearance] tintColor];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:dataToShare applicationActivities:nil];
[activityViewController setCompletionHandler:^(NSString *activityType, BOOL completed) {
      // back to normal color
     [[UINavigationBar appearance] setTintColor:normalColor];
}];

[self presentViewController:activityViewController animated:YES completion:^{
     // change color to suit your need
     [[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:25.0f/255.0f green:125.0f/255.0f blue:255.0f/255.0f alpha:1.0f]]; // ActionSheet options' Blue color
}];
