tableheaderview覆盖了部分cell的解决方法

<p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo; color: rgb(0, 132, 0);"><pre name="code" class="objc">
- (UIView *)getHeaderView:(UIView *)xibHeader
{
CGRect rect = xibHeader.frame;
rect.size.width = ScreenWidth;
CGSize size = [xibHeader systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
rect.size.height = size.height;
xibHeader.frame = rect;
return xibHeader;
}
- (void)viewDidLayoutSubviews
{
[super viewDidLayoutSubviews];
self.mTableView.tableHeaderView = [self getHeaderView:self.detailHeadView];
}

<span style="font-family: Menlo;"> [self.detailHeadView setData:dic];</span>

[self.mTableView setTableHeaderView:[self getHeaderView:self.detailHeadView]];
