/** 键盘谈起屏幕偏移量 */

@property (nonatomic, assign) CGPoint keyBoardPoint;

    [[NSNotificationCenter defaultCenter] addObserverForName:UIKeyboardWillShowNotification object:nil queue:[NSOperationQueue currentQueue] usingBlock:^(NSNotification * _Nonnull note) {

//        [ws.webView layoutSubviews];//TODO:

        CGPoint point = ws.webView.scrollView.contentOffset;

        ws.keyBoardPoint= point;

    }];

    [[NSNotificationCenter defaultCenter] addObserverForName:UIKeyboardWillHideNotification object:nil queue:[NSOperationQueue currentQueue] usingBlock:^(NSNotification * _Nonnull note) {

//        [ws.webView layoutSubviews];//TODO:

        ws.webView.scrollView.contentOffset = ws.keyBoardPoint;

        ws.webView.bounds = ws.view.bounds;

        ws.webView.scrollView.contentOffset = CGPointMake(0, 0);

    }];

这里使用layoutSubviews 或者重设contentOffset都可以解决这个问题
