How to set dynamic height of cell based on content

Question

I am have an app which requires to display user comments within a table cell. How can I set the dynamic height of the cell based on the contents of the cell like in Instagram?

Answer 1

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.
