UIAlertController status bar not dimming and tint color issues

Question

I am migrating from using UIAlertView to the UIAlertController introduced in iOS 8. However, I am seeing a few strange view issues I don't see when using UIAlertView. First, when displaying an alert, the status bar text doesn't dim:

Also, after displaying the status bar, the back arrow in the UINavigationController is now set to the application's tintColor rather than the white tintColor I set for the UINavigationBar. This affects other UINavigationBar elements throughout the application, such as Add (+) buttons and Edit buttons. Before displaying the UIAlertController, all of the bar button items were showing up as white.

I'm at a loss here. My code for displaying the alert is very straightforward:

UIAlertController *view = [UIAlertController alertControllerWithTitle:VALIDATION_TITLE message:text preferredStyle:UIAlertControllerStyleAlert];
[view addAction:[UIAlertAction actionWithTitle:VALIDATION_BUTTON_OK style:UIAlertActionStyleDefault handler:nil]];
[self presentViewController:view animated:YES completion:nil];

when u press ok on alert, the alert dismisses, and then the back arrow is dimmed ? Can you show the code related to the back button ? — Teja Nandamuri, Feb 01 '16 at 18:20
The back arrow isn't actually dimmed; it is set to the global `tintColor` which is greenish/blue. The back arrow doesn't show that color immediately, but will show the new `tintColor` when I toggle away and back to the screen via the tab bar at the bottom. There really isn't any code related to the back button... it is a regular `UINavigationController`. — Dan, Feb 01 '16 at 19:14
Yes, but again not until I navigate away from my view controller and back to it. — Dan, Feb 01 '16 at 19:37

So, when dealing with diplaying UIAlertControllers when I don't have a handle to the displaying UIViewController, I found the following code on stackoverflow:

If I use the show: method, which invokes a new UIWindow and presents the UIAlertController from that new window, I don't have any of the UI side effects that I see above when displaying an alert.

If someone knows why this is happening, please still answer this question because this is a fairly hacky workaround!
