Updated for iOS 11.

[iosdevzone]

The structure of UINavigationBar has changed in iOS 11. This meant that navigation bar was not fading out and was clashing with the status bar. I modified the code to recursively apply the new alpha value. The change should be benign on older OS versions.

This PR may solve issue #67.

If you push a view controller to the hiding navigation controller, the nav bar buttons are delayed in dismissing when popped.

Thanks for this fix and sorry it took so long to merge, I completely missed this PR.

@tristanhimmelman This change appears to have broken pop animations in our UINavigationBar -- specifically the way the back button animates after you tap it.

This is using Xcode 9.4.1 and iOS 11.

This change also caused issues when the NavigationBar has a UISearchBar inside of it. It causes the search bars Cancel button to appear when the bar expands. For our case, just made it skip changing the alpha for that specific button.

Hey guys, sorry to hear that. If one of you would be willing to create a PR to revert the change I would be happy to review and merge it. Unfortunately I just dont have the time to make updates myself at the moment. Thanks

@tristanhimmelman I would be happy to open up a PR to revert this change, but I was unclear what the original change was hoping to accomplish and what reverting this PR might affect. However, if you'd like that PR just let me know. Or, you can always easily revert a PR on GitHub using the Revert button above next to the line item:

Hi all,

Sorry this change is causing issues. It was initially introduced to solve a problem with iOS 11 where you were left with your back button still visible and overlaying the status bar. This still occurs in iOS 12 for the iPhone X (perhaps it only occurred on this model for iOS 11?, I don't have an emulator or device handy at the moment).

Here's what you'll get if you simply revert and run the sample project. (Run on device, iOS 12, iPhone X).

Apologies for the delay in responding to this thread, I've been away from iOS development for a while as my day job has been hectic.
