Summary:
When using an alertView for text input, button actions dismiss the keyboard with a noticeable delay.

Steps to Reproduce:
- present alertView (ensure alertView calls `addTextFieldWithConfigurationHandler`)
- Use a button action on the alertView to complete input (ie. Save in example project)

Expected Results:
Keyboard should dismiss immediately

Actual Results:
Keyboard dismisses after a 1-3 second delay (ie, on dealloc)

Version:
iOS 9

Notes:
Using the return key on the keyboard has the expected result, only dismissing via the alert actions shows the delay.
