Self growing label in tableview cell

问题

I am working with Tableview in Objective C.

I have 4 labels in a TableView cell. I want to expand the Comment Body label and Answer Body label according to the content size. How it is possible using AutoLayout. Please help me

How to set dynamic height of label as per content?

The ScreenShot of the tableview is given below.

回答1:

Your constraint should be like,

Comment -> top, leading(left side), fixed width, fixed height

Answer -> top, leading, fixed width, fixed height

Comment Body -> top, leading, trailing (right side), fixed height (greater than or equal to some constant value), bottom

Answer Body -> top, leading, trailing, bottom

Make sure that number of lines for comment body and answer body must be 0.

and you have to set estimatedrowheight and row height for your tableview like,

  self.yourTableView.estimatedRowHeight = 50;
  self.yourTableView.rowHeight = UITableViewAutomaticDimension;

-(CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath {

      return 50;
  }

 - (CGFloat)tableView:(UITableView *)_tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{

     return UITableViewAutomaticDimension;
}
