UIView dynamic height depending on Label Height

Question

I have a Label which takes dynamicaly some data from database. These data are strings which can sometimes be 3-4-5 rows etc. So this labe is inside a UIView.

Answer 1

Bellow is working solution of your problem. I used autoLayout. In testView you don't set heightAnchor

let testView: UIView = {
    let view = UIView()
    view.translatesAutoresizingMaskIntoConstraints = false
    view.backgroundColor = UIColor.redColor()
    return view
}()

let testLabel: UILabel = {
    let label = UILabel()
    label.numberOfLines = 0
    label.translatesAutoresizingMaskIntoConstraints = false
    label.text = "jashfklhaslkfhaslkjdhflksadhflkasdhlkasdhflkadshkfdsjh"
    return label
}()


override func viewDidLoad() {
    super.viewDidLoad()

    view.addSubview(testView)
    testView.centerXAnchor.constraintEqualToAnchor(view.centerXAnchor).active = true
    testView.centerYAnchor.constraintEqualToAnchor(view.centerYAnchor).active = true
    testView.widthAnchor.constraintEqualToConstant(100).active = true


    testView.addSubview(testLabel)
    testLabel.topAnchor.constraintEqualToAnchor(testView.topAnchor, constant: 10).active = true
    testLabel.leftAnchor.constraintEqualToAnchor(testView.leftAnchor, constant: 10).active = true
    testLabel.bottomAnchor.constraintEqualToAnchor(testView.bottomAnchor, constant: -10).active = true
    testLabel.rightAnchor.constraintEqualToAnchor(testView.rightAnchor, constant: -10).active = true

}
