我试了下，可以解决问题，不保证不出BUG
在INSPullToRefreshBackgroundView.m 文件

• (instancetype)initWithHeight:(CGFloat)height scrollView:(UIScrollView *)scrollView方法中
  if (self = [super initWithFrame:frame]) {括号里最后一行添加代码}
  代码如下：

       if (@available(iOS 11.0, *)) {
            _scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
            _scrollView.contentInset = UIEdgeInsetsMake(64, 0, 49, 0);
            _scrollView.scrollIndicatorInsets = _scrollView.contentInset;
        }

添加完成完整后：

- (instancetype)initWithHeight:(CGFloat)height scrollView:(UIScrollView *)scrollView {
    NSParameterAssert(height > 0.0f);
    NSParameterAssert(scrollView);
    
    CGRect frame = CGRectMake(0.0f, 0.0f, 0.0f, height);
    if (self = [super initWithFrame:frame]) {
        _dragToTriggerOffset = INSPullToRefreshDefaultDragToTriggerOffset;
        _scrollView = scrollView;
        _externalContentInset = scrollView.contentInset;
        self.autoresizingMask = UIViewAutoresizingFlexibleWidth;
        _state = INSPullToRefreshBackgroundViewStateNone;
        _preserveContentInset = NO;
        _scrollToTopAfterEndRefreshing = YES;
        _enabled = YES;
        _shouldResetContentInsetDuringRotation = YES;
        [self resetFrame];
        
        if (@available(iOS 11.0, *)) {
            _scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
            _scrollView.contentInset = UIEdgeInsetsMake(64, 0, 49, 0);
            _scrollView.scrollIndicatorInsets = _scrollView.contentInset;
        }
    }
    return self;
}
