iOS11 automaticallyAdjustsScrollViewInsets不起作用

当升级到iOS 11的时候,发现UIScrollView 有莫名其妙的偏移了 可是明明设置了

automaticallyAdjustsScrollViewInsets

这是因为iOS 11为UIScrollView 添加了新的属性contentInsetAdjustmentBehavior 这是一个枚举
swift
if #available(iOS 11.0, *) {
scrollView.contentInsetAdjustmentBehavior = .never
} else {
// Fallback on earlier versions
}

oc
if (@available(iOS 11.0, *)) {

        Scrollview.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;

    } else {

        // Fallback on earlier versions

    }
