objective c - Lag When Activating Text Field Inside iOS 8 Custom Keyboard -

i want add together search field within custom keyboard allows user search content can input main text document keyboard beingness displayed.

however, calling -becomefirstresponder on uitextfield object causes 3-4 sec lag during no input accepted. same thing happens if phone call -resignfirstresponder. can set text property of text field fine, means there no caret, , text truncated fit.

on calling (become|resign)firstresponder, next messages in log:

other 3rd party keyboards seem not utilize textfields (they utilize custom views instead). mean bug @ apple's end, or there can resolve it?
