Summary:
This bug occurs only on iPhone 6 plus. The Keyboard doesn't hide on a modal pushed ViewController after an orientation change. Both ways (resignFirstResponder and endEditing) was tested, both function calls returns with a "true" value, but the keyboard is still visible on the screen. If I start the app in landscape modus, the methods works like expected.

I tested the same code on a iPhone 6 and the methods works like expected.

Steps to Reproduce:
1. Open example app in portrait modus
2. Tap on the open button (to push a modal ViewController)
3. Tap on the TextField to open the Keyboard (becomeFirstResponder)
4. Tap on the Done Button within the accessoryView -> Everything works fine
5. Rotate Device to Landscape modus and tap again on the TextField
6. Tap on the Done Button again -> Keyboard is still visible
7. Tap on the keyboard button to hide the keyboard is working correctly.

Expected Results:
If I call resignFirstResponder or endEditing(true) then the Keyboard should disappear on every device in every orientation.

Actual Results:
The Keyboard is still visible even though I called the resignFirstResponder or endEditing method. This occurs only on iPhone 6 plus.
