问题
I am using iOS 9 and Xcode 7 ....and I make new app without storyboard and use auto layout and use size classes.....basically I am using xib with resizing feature and use code to check device . When I was using xcode 6.4 and iOS 8 then my code work for each device . But when I use Xcode 7 and iOS 9 then screen not show full on device this is only for iPhone 6 and above. I attached image here...
See In image black part appear on each screen for iPhone 6 and above.....I add all launch images on launch image View....but I don't know why this problem appear.
and If I'm not added launch images and without that run code this view like this..........I this this is problem related to launch screen.

You need to set the launch screen for these devices. or your view background color is black. and you didn't set the constraint for the UIImageView.
