iphone push view by storyboard segue the Navigation Bar flickers black when animating

i development use xcode 9.2 and swift 4.0.3


and then create a segue (show:push) in storyboard





Everything was fine at first, but after a while the push animation was not working properly.







I don’t know how this happened, how to solve it? thx!
