UIMenuController hides the keyboard

I currently have an application which is for chatting. I used a UItextField for input box and bubbles for display messages, some thing like the system SMS. I want to enable copy paste on the message bubbles (labels). The problem is, when I want to show the UIMenuController, the label which i need to copy from need to become first responder. If the keyboard is currently displayed, when the label become first responder, the textfield will lost focus, thus the keyboard will be hide automatically. this cause an UI scroll and feels not good. Is there anyway that i can keep the keyboard shown even when i need to show the menu?

You can try to subclass your uitextfield and override the firstresponder. Check in your long press gesture handler if the uitextfield is the first responder and override the nextresponder.
