ios内嵌H5沉浸式状态栏无法覆盖

iOS 内嵌H5中, 存在沉浸式情况下, h5内容无法覆盖状态栏的问题

解决办法

1）iOS添加代码

    if (@available(iOS 11.0, *)) {
        g_web.scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
    } else {
        self.edgesForExtendedLayout = UIRectEdgeNone;
    }

2）H5 添加meta

<meta name="viewport" content=" viewport-fit=cover">

添加了viewport-fit=cover放到IOS机上就可以全屏了
