I am not sure that anyone has encountered such kind of a behavior or not but iOS9 is making my UIAlertController tint to inherit from the main window. Is there any specific way something like UIAppearance that can help and resolve the issue.
[[UICollectionViewCell appearanceWhenContainedIn:[UIAlertController class], nil] setTintColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:1]];
Have you set the UIWindow color in the AppDelegate like
func application(application: UIApplication, didFinishLaunchingWithOptionslaunchOptions: [NSObject: AnyObject]?) -> Bool
{
window?.tintColor = .redColor()
}
At least this worked for me
