如何在UITableView中显示iMessage iPhone应用程序的时间

Question

我无法在iTessage iPhone应用程序中滑动时在UITableView中显示时间。我启用了属性：显示水平滚动条和垂直弹跳。但它作为iMessage应用程序无法正常工作。它需要shrike UITableViewCell内容并显示时间。

{
    if (self.isOpen && self.selectIndex.section == indexPath.section)
    {
        NujMessage *message = [self.sectionMessages objectAtIndex:indexPath.section];

        if(indexPath.row == 0)
        {
            int nujHeight = message.isNuj ?   15 : 0;
            int cellHeight = message.size.height + kMargin + nujHeight;


            if([message.moreMessages count] > 0)
            {
                return cellHeight > kNujMessageHeight ? cellHeight : kNujMessageHeight;
            }
            else
            {
                return cellHeight > kSectionHeaderHeight ? cellHeight : kSectionHeaderHeight ;
            }
        }
        else{

            int moreMsgCount = [message.moreMessages count];


            if(indexPath.row == 1 && message.size.height <= 70)
            {
                message = [message.moreMessages objectAtIndex:indexPath.row - 1];
                [self setMakeSizeOfMessage:message];
