I have been messing with these constraints for hours and cannot figure this out. I need to have Dynamic cell height with my text view.

As you can see its o

Answer 1

For Swift 3.1, 4.0

It will be achieved by setting constraints and UITableViewAutomaticDimensions.

Step 1:

Step 2:

Step 3:

Step 4:

Remove Scrolling for UITextView

Step 5:

Add Below code,

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {

    return UITableViewAutomaticDimension
}

Note:

If you have UILabel then, Replace UITextView to UILabel from above solution and label.numberOfLines = 0.

Output:

Answer 2

User vertical spacing between the timeStamp and the message, and set the constant to >=2

Answer 3

If your cell height is dependent on text size then follow this: Add the method in your ViewController.swift

    func calculateHeight(inString:String) -> CGFloat {
         let messageString = inString
         let attributes : [String : Any] = [NSFontAttributeName : UIFont.systemFont(ofSize: 15.0)]

     let attributedString : NSAttributedString = NSAttributedString(string: messageString, attributes: attributes)

     let rect : CGRect = attributedString.boundingRect(with: CGSize(width: 222.0, height: CGFloat.greatestFiniteMagnitude), options: .usesLineFragmentOrigin, context: nil)

      let requredSize:CGRect = rect
      return requredSize.height
}

Set the width of your text label Then call this function:

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
            heightOfRow = self.calculateHeight(inString: conversations[indexPath.row].description)

            return (heightOfRow + 60.0)
    }

For Basic cell:

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
           return UITableViewAutomaticDimension
    }

This function will not work for custom cells.

If your cell height is dependent on image height, then return image height + someFloatValueAccordingToYourChoice.

Hope it will work.
