前言：
IQKeyboardManagerSwift 可以在開發App時讓 UITextField、UITextView 防止鍵盤向上滑動和覆蓋的問題，則可以在 PodFile 加入這個套件 IQKeyboardManagerSwift

正文：
加入方法和 Realm、youtube_ios_player_helpe 加入時一樣
不過程式碼要加在 AppDelegate.swift

預覽圖：

程式碼：

import UIKit
import IQKeyboardManagerSwift
@main
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

      IQKeyboardManager.shared.enable = true

      return true
    }

    // MARK: UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
    }
