7,009 Pointsconstrains not showing up in main.storyboard
so I am trying to add constrains in code, but they don't show up in main.storyboard and obviously they don't work
import UIKit
class ViewController: UIViewController {
@IBOutlet weak var button1: UIButton!
@IBOutlet weak var button2: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
addConstraints()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func addConstraints() {
let button1topEdge = NSLayoutConstraint(item: button1, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 0.0)
let button1Center = NSLayoutConstraint(item: button1, attribute: .centerX, relatedBy: .equal, toItem: view, attribute: .centerX, multiplier: 1.0, constant: 0.0)
let button1Height = NSLayoutConstraint(item: button1, attribute: .height, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute, multiplier: 80.0, constant: 0.0)
let button1widthConstraint = NSLayoutConstraint(item: button1, attribute: .width, relatedBy: .equal, toItem: view, attribute: .height, multiplier: 1.0, constant: 0.0)
let button2widthConstraint = NSLayoutConstraint(item: button2, attribute: .width, relatedBy: .equal, toItem: view, attribute: .height, multiplier: 1.0, constant: 0.0)
view.addConstraints([button1Height,button1Center,button1topEdge,button1widthConstraint,button2widthConstraint])
}
