LifeCycle of iOS app
* App's Life Cycle
import UIKit
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
// 應用程式初始化
func applicationDidFinishLaunching(_ application: UIApplication) {
<#code#>
}
// 應用程式初始化後
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
//即將啟動 Running phase
func applicationDidBecomeActive(_ application: UIApplication) {
<#code#>
}
//進入前景 (使用者使用中)
func applicationWillEnterForeground(_ application: UIApplication) {
<#code#>
}
// 使用者離開活動中
func applicationWillResignActive(_ application: UIApplication) {
<#code#>
}
// 進入背景
func applicationDidEnterBackground(_ application: UIApplication) {
<#code#>
}
// 閒置過久，檢查記憶體與存儲空間，如不足，被迫移除（釋放資源）。
func applicationWillTerminate(_ application: UIApplication) {
<#code#>
}
---------- 下方無關生命週期重要階段 ------------------------------------
// 記憶體不足提醒
func applicationDidReceiveMemoryWarning(_ application: UIApplication) {
<#code#>
}
// 時間相關
func applicationSignificantTimeChange(_ application: UIApplication) {
<#code#>
}
// 資料相關
func applicationProtectedDataDidBecomeAvailable(_ application: UIApplication) {
<#code#>
}
func applicationProtectedDataWillBecomeUnavailable(_ application: UIApplication) {
<#code#>
}
// Auth
func applicationShouldRequestHealthAuthorization(_ application: UIApplication) {
<#code#>
}
}
* Download App
一旦 app 下載進入手機設備中的磁碟內時，App 的生命週期就開始了，請詳 AppDelegate。
而通常本地端的推播功能就是設計於此環節，能讓使用者在沒有網路的情況下，能接受 app 定時設計好的推送訊息。
https://github.com/QueenieCplusplus/iOS_Back_15 (示範範例)
* Open App
當使用者啟動 app，進入畫面即前景 ，則畫面的生命週期便是展開，請詳 ViewController。
* Press Home button
按下 Home 鍵，雖然前景畫面跑回了手機主頁，然而針對某些特殊設計的應用程式（開發者設定為可於背景執行）則地圖 app 、音樂 app、資料撈取、遠端推播 remote notification、藍芽 BLE 功能的 app 因應 CPU 資源和電池電量的資源供給量（主要供給予前景執行的 app）均能於背景（使用者即便看不見應用程式畫面）亦能執行任務，方便使用者繼續更新地圖、聆聽音樂、下載資料。

* Lock Screen
使用者因為一定時間內沒有與手機互動，系統為保安全，便會鎖定螢幕，此階段與按下 Home 鍵的執行方式一樣。
