一、加载cell的时候动态的计算高度
OrderDetailTableViewCell *cell = [self cellAtCellDicWithIndexPath:indexPath];

float cellHight=cell?(cell.isExpand?cell.cellHight.selectedHight:cell.cellHight.normalHight):cell.cellHight.normalHight;

return cellHight;

二、HUD 基础的文本展示
调用方法 afterDelay为关闭的延时秒数

[KziwwsTextIndicatorView showTextIndicatorViewMessage:@"这是Kziwws HUD,一个善良有梦想安静的程序员" afterDelay:0.5 isMaskGray:NO];
