在Xcode中使用自由格式的模拟尺寸时，如何使屏幕适应？

Question

I am making an app and I have a UIScroll view in my viewController. I have set the simulated size to freeform and the height to 2000 and width to 375. When I run my app on the Iphone 7 There are no problems. But when I try to run the app on the iphone 7plus the screen does not adapt and i get these white bars on the right side because my contents width is only 375 pixels. So how can I make my screen to automatically go bigger when I use a bigger device?

如果尚未完成，则应在UIScrollView添加约束（后缀，前导，顶部空间，底部空间），以将其固定到超级视图范围。
