前言:建议创建Flutter项目时候直接使用命令行，不用Android Studio等第三方工具创建,否则会出现项目创建卡顿，或者pod install 各种失败
-
1.新建一个公有文件夹
flutter 混合开发，用来放Flutter项目和iOS项目
-
2.cd到
flutter 混合开发该目录，执行创建flutter模块，终端执行flutter create --template module my_flutter -
3.新建iOS原生项目为
Demo,一并放到flutter 混合开发，目录结构如下：
-
4.cd到iOS目录，分别执行以下命令
pod init
pod install
打开 podfile文件，配置如下图三部分命令
flutter_application_path = '../my_flutter' #这是你本地flutter目录的路径
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')
install_all_flutter_pods(flutter_application_path)
#新增的配置
post_install do |installer|
flutter_post_install(installer) if defined?(flutter_post_install)
end
请注意查看路径
./my_flutter
./和../ 这个是linux命令
./代表当前目录
../代表目录下级
以上配置完成后，cd到iOS项目目录，再次执行 pod install
-
5.原生代码配置
为了在既有的iOS应用中展示Flutter页面，需要启动
Flutter Engine和FlutterViewController。 通常建议为我们的应用预热一个长时间存活的FlutterEngine： 我们将在应用启动的 app delegate 中创建一个FlutterEngine，并作为属性暴露给外界。 -
Swift篇：
import UIKit
import FlutterPluginRegistrant
@UIApplicationMain
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 {
// 2.启动flutterEngine
flutterEngine.run()
return true
}
}
- Object-C篇：
- AppDelegate.h代码：
@import UIKit;
@import Flutter;
@interface AppDelegate : FlutterAppDelegate
@property (nonatomic,strong) FlutterEngine *flutterEngine;
@end
- AppDelegate.m代码：
#import <FlutterPluginRegistrant/GeneratedPluginRegistrant.h> // Used to connect plugins.
#import "AppDelegate.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary<UIApplicationLaunchOptionsKey, id> *)launchOptions {
self.flutterEngine = [[FlutterEngine alloc] initWithName:@"my flutter engine"];
[self.flutterEngine run];
[GeneratedPluginRegistrant registerWithRegistry:self.flutterEngine];
return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end
