Check the UITableViewDelegate documentation.
- (CGFloat)tableView:(UITableView *)tableView
heightForRowAtIndexPath:(NSIndexPath *)indexPath
Bear in mind you can't reference the cell from this method, so you want to calculate the height of the contents separately and use it to generate the height.
请记住，您无法通过此方法引用单元格，因此您需要单独计算内容的高度并使用它来生成高度。
