【iOS】今更聞けないUIViewControllerのライフサイクル その2 (Swift)

過去に書いていたのですが、意外と観ていただいている人がいたので、更新版です

忘れやすいですよね

もう少し、細かいイベントを追加しました

表示する時

• awakeFromNib
• loadView
• viewDidLoad
• loadViewIfNeeded
• viewWillAppear
• viewLayoutMarginsDidChange
• viewSafeAreaInsetsDidChange
• updateViewConstraints
• viewIsAppearing
• viewWillLayoutSubviews
• viewDidLayoutSubviews
• viewDidAppear

別ページ表示する時

• viewWillLayoutSubviews
• viewDidLayoutSubviews
• viewWillDisappear
• viewWillLayoutSubviews
• viewDidLayoutSubviews
• viewDidDisappear

import UIKit

    override func awakeFromNib() {
        super.awakeFromNib()
        print("awakeFromNib")
    }
    
    override func loadView() {
        super.loadView()
        print("loadView")
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        print("viewDidLoad")
    }
    override func loadViewIfNeeded() {
        super.loadViewIfNeeded()
        print("loadViewIfNeeded")
    }
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        print("viewWillAppear")
