I have a storyboard I am building for an iPhone 6 Plus and iPhone 6s application. For some reason, when I run the application on the iPhone 6 Plus the screen is cut off but on the 6s Plus everything fits on the screen. Is the screen size different? Also, is there a way to find out what if the user is using an iPhone 6s or 6 Plus?
You may want to use Auto Layout

Debug your screen with
po [[UIWindow keyWindow] _autolayoutTrace]
Check if user is using an iPhone 6 or 6 Plus
