This is a bug in the xcode6 simulator. If the Keyboard is unavailable, You can manually activate the Keyboard through Hardware-> Keyboard-> Toggle Software Keyboard.

In ios, how does one set clearbutton and ensure that the virtual keyboard does not always pop up?

The virtual keyboard does not come out of clearbutton, does it matter? The virtual keyboard is not the first responder. You can set it in the UITextField proxy method and the method at the end of editing. Another is to click somewhere else on the screen to let the screen go down. There is a way to cancel the first response and execute it. Clearbutton only clears the entered content.
 
In IOS software development, how does UITextField cancel the pop-up system keyboard?

Why must we focus? On your own keyboard, you can press the key to modify textField. text.
