iOS viewDidLoad for UIView

Question

In a ViewController, there is ViewDidLoad to know when the VC has loaded.

For a UIView, what method do i have to use when the view loaded?

Would this method be called with any init?

edit: No XIB, just programmatically.

Answer 1

If you load it from a XIB file, the awakeFromNib method will be called once loading finishes:

override public func awakeFromNib() {     super.awakeFromNib();      // ... loading logic here ... } 

Update; In the case of no XIB, you will probably have to infer it using one of the methods from the Observing View-Related Changes area of the docs (for example, didMoveToSuperview). However, a better way is to send a message to your views from the view controller's viewDidLoad method if possible.

Answer 2

You can use willMove(toSuperview newSuperview: UIView?)

import UIKit  final class myView: UIView {    override func willMove(toSuperview newSuperview: UIView?) {      super.willMove(toSuperview: newSuperview)      //Do stuff here    }  }
