automaticallyAdjustsScrollViewInsets 和 contentInsetAdjustmentBehavior

iOS 11中ViewController的automaticallyAdjustsScrollViewInsets属性被废弃了

if (@available(iOS 11.0, *)){//适配iOS11MJRefresh顶部多出的一部分
        [[UIScrollView appearance] setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentNever];
    }
    if (@available(iOS 11.0, *)){网页适配
        self.webView.scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
    }else{
        self.automaticallyAdjustsScrollViewInsets = NO;
    }
