How to get rid of safeAreaInsets on UIScrollview (iOS 11, iPhoneX)

问题

I have a horizontal paging UIScrollview, following is my VFL constraints for leading/trailing H:|-0-[ScrollView]-0-| (aligned to superview).

I have left/right safeAreaInsets on landscape orientation in iPhone X.

Is it a bug? or I am missing any Apple way that these insets will not be applied when we do not need?

回答1:

I am using following to skip content inset adjustment:

UIScrollview.contentInsetAdjustmentBehavior = .never

I found that in iOS 11 UIScrollViewContentInsetAdjustmentBehavior.always includes safe area layout guide and apply these margins as insets, so tried .never it worked ))

回答2:

If you set UIScrollview.contentInsetAdjustmentBehavior = .never, you'll be responsible for applying the insets. If you let to the default value, any time the view needs to be redrawn, the framework will override your settings
