今天小编给大家分享一下iOS项目嵌入Flutter运行的方法是什么的相关知识点,内容详细,逻辑清晰,相信大部分人都还太了解这方面的知识,所以分享这篇文章给大家参考一下,希望大家阅读完这篇文章后有所收获,下面我们一起来了解一下吧。
命令行
flutter create --template module my_flutter
创建完成后,该模块和普通的Flutter项目一直,可以通过Android Studio或VSCode打开、开发、运行;
和之前项目不同的iOS和Android项目是一个隐藏文件,并且我们通常不会单独打开它们再来运行;
它们的作用是将Flutter Module进行编译,之后继承到现有的项目中
my_flutter/ ├── .ios/ ├── .android/ ├── lib/ │ └── main.dart ├── test/ └── pubspec.yaml
主要是通过pod 进行设置,之后pod install
注意my_flutter 的路径对不对
platform :ios, '12.0' # 添加模块所在路径 flutter_application_path = '../my_flutter' load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb') target 'FlutterHybridDemo' do # Comment the next line if you don't want to use dynamic frameworks use_frameworks! # 安装Flutter模块 install_all_flutter_pods(flutter_application_path) # Pods for FlutterHybridDemo end post_install do |installer| flutter_post_install(installer) if defined?(flutter_post_install) end
为了在既有的iOS应用中展示Flutter页面,需要启动 Flutter Engine和 FlutterViewController
AppDelegate 中设置代码
import UIKit import FlutterPluginRegistrant @main class AppDelegate: UIResponder, UIApplicationDelegate { // 1.创建一个FlutterEngine对象 lazy var flutterEngine = FlutterEngine(name:"my flutter engine") func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { // Override point for customization after application launch. // 2 启动 flutterEngine.run() return true }
在ViewControlelr 设置的代码
import UIKit import Flutter class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. let btn = UIButton(type: UIButton.ButtonType.custom) btn.setTitle("加载flutter", for: UIControl.State.normal) btn.frame = CGRect(x: 50, y: 50, width: 200, height: 50) btn.backgroundColor = UIColor.blue btn.addTarget(self, action: #selector(showFlutter), for: UIControl.Event.touchUpInside) view.addSubview(btn) } @objc func showFlutter(){ let flutterEngine = (UIApplication.shared.delegate as! AppDelegate).flutterEngine let flutterController = FlutterViewController(engine:flutterEngine, nibName: nil, bundle: nil) present(flutterController, animated: true) } }
显示的结果 顺利加载出flutter 的页面
