动态uitableviewcell高度根据自定义单元格高度

Question

我想知道，有没有办法读取你将在你的uitableviewcell中使用的自定义tableview单元格的高度，然后你可以对你的uitableviewcell说这个--->高度？

Answer 1

I am not fully understand your question but do you want to set the height for each custom cell ? If yes then you can do it by :

Let say I have custom cell at index 0 rest are my default cells or can be custom cell as well .

- (CGFloat)tableView:(UITableView *)_tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.row == 0 ) {
       return 105.0;
    }else {
        return 80.0;
    }
}

Answer 2

No, the height that you set in the xib/storyboard is for display purposes only and doesn't transfer over to code.

The only way to change the height is from your custom subclass, by overriding tableView:heightForRowAtIndexPath: .

If you have a lot of different heights, you could always subclass UITableViewCell and add a height property which tableView:heightForRowAtIndexPath: uses when it sees your subclass. Then, in your storyboard, select your cell, go to the identity inspector, and add a User Defined Runtime Attribute for height with the value that you need.
