Change cell height by the content of the textView inside the cell

问题

I have a Table View called todoTableView with cells that created by the user. Each cell has Text View. I want to change the height of the cell by the content of the Text View. This is what I tried:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell: TableViewCell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath:indexPath) as! TableViewCell
        cell.bounds.size.height = cell.textView.bounds.size.height

        return cell
    }

回答1:

Bound Your textview with cell from all sides using marginal constraints.(Leading, Trailing, Top and Bottom constraints)

• Disable textView Scrolling

In viewDidLoad() add the following.

tableView.estimatedRowHeight = 44.0
tableView.rowHeight = UITableViewAutomaticDimension

This will make your cell size according to your textview content size.

Have a look at result :

You don't need to write heightForRowAtIndexPath.

Irfan's answer didn't work for me.

It works after I go to Size Inspector and check "Automatic" for "Row Height".

You should also implement heightForRowAtIndexPath:

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat 
{
    return // Calculate your custom row height here.
}
