How to call CustomDelegate functions Textfield takes it's new size

Question

I want to create a custom UITextfield and I have this problem.

I want to add some labels below the UITextField and the problem is that when I compute the position of the label it does't take the position based on the device size but based on the storyboard size.

To be more spesific my code is

private func setUpBottomRightLabel(){
    let height:CGFloat = self.layer.frame.height / 2
    let lBottomRight = UILabel(frame: CGRect(x: self.frame.origin.x, y: self.frame.origin.y + self.frame.height + 2, width: self.frame.width * 0.6, height: height))
    lBottomRight.font = UIFont(name: "System", size: 4)
    lBottomRight.text = "\(self.text?.count ?? 0)/\(self.maxNumber)"
    lBottomRight.textAlignment = .right
    lBottomRight.backgroundColor = UIColor.red
    self.superview!.addSubview(lBottomRight)
    self.updateConstraints()
    self.layoutIfNeeded()
}

And the problem is that when this function is being called from awakeFromNib() or init() the textfield self.frame.width = 359 but when the ViewControllers function ViewDidAppear is being called the CustomTextField.frame.width is 304.0.

Witch delegate method should I call from CustomTextField file to call the methods that add the labels to the Textfield that will that will take the size based on the phone?

Answer 1

In your CustomTextField, override the layoutSubviews as below to get the correct frame and then add the bottom label

class CustomTextField: UITextField {

    override func layoutSubviews() {
        print("\(self.frame)")
    }
}
