How To Increase the height of MDCTextInputControllerOutlinedTextArea

问题

I have assigned a class named MDCMultilineTextField for Uiview from the storyboard. This class is used for Multiline TextView. My Uiview height is 400(not fix) but my UiView border is not same as height, Please verify my code and you can see screenshot below.

        import MaterialComponents    

        @IBOutlet var viewTextView: MDCMultilineTextField!
        @IBOutlet var btnDone: UIButton!
        var notes=""
        var dismissView: ((_ text:String) -> Void)?
        var desc: MDCTextInputControllerOutlinedTextArea?
       override func viewDidLoad()
        {
           desc = MDCTextInputControllerOutlinedTextArea(textInput: viewTextView)
           viewTextView.placeholder="Description"
           viewTextView.backgroundColor = UIColor.yellow
           if notes != ""
            {
                textView.text = notes
                viewTextView.text = notes
            }
    }

回答1:

You can assign MDCMultilineTextField.layoutDelegate to UIView container. It will change the container size based on MDCMultilineTextField height.

try this

NSLayoutConstraint(item: multilineTextField.textView, attribute: .bottom, relatedBy: .equal, toItem: multilineTextField.borderView, attribute: .bottom, multiplier: 1.0, constant: 0).isActive = true
