一、 iOS 旧项目添加CocoaPods
1、cd 到项目根目录,生成Podfile文档：
2、 执行 ：open -a xcode podfile 打开 1 生成的podfile文件
3、 在podfile 内添加需要的第三方插件，更改了podfile 记得update
（ps:1： 需要的插件自己去pod search XXX 2:注意平台前注释 # 去掉）
4、 执行pod install --verbose --no-repo-update
至此cocoaPods 添加完成 ，运行工程，发现Podfile 内添加的头文件无法找到，继续
5、 选择Target - Build Settings 搜索User Header 双击User Header Search Paths 填空如下：
二、 创建flutter_mould
官方建议的混合开发模式，必须要创建flutter_mould
1、命令行创建： `flutter create -t module flutter_module`
2、 创建的项目路径要选择好，一般我们会与原生项目目录并排，如下：
三、 关联 flutter_mould
1、在iOS工程的poffile文件中添加如下命令：
flutter_application_path='../flutter_demo' #这里是我们创建的flutter_module的路径
load File.join(flutter_application_path,'.ios','Flutter','podhelper.rb')
target 'XXXAPP' do
use_frameworks!
# Flutter
install_all_flutter_pods(flutter_application_path)
end
2、 执行Pod
输入命令 `pod install`
3、解决报错
首先 让我们的iOS项目 关联 Flutter模块，实用cocoapods关联，在podfile文件里添加如下代码
flutter_application_path = '../flutter_module' //flutter模块的路径
load File.join(flutter_application_path,'.iOS','Flutter','podhelper.rb') //函数调用加载flutter
platform :ios, '12.0'
target 'NativeDemo' do
install_all_flutter_pods(flutter_application_path)
use_frameworks!
# Pods for NativeDemo
end
第一次 ` pod install` 报错：
[!] Invalid `Podfile` file: Missing `flutter_post_install(installer)` in Podfile `post_install` block.
# from /Users/zhangfan/Desktop/flutter_folder/NativeDemo/Podfile:7
# -------------------------------------------
# target 'NativeDemo' do
> install_all_flutter_pods(flutter_application_path)
# use_frameworks!
# -------------------------------------------
处理方法：
在podfile结尾添加
target 'app' do
// 用的各sdk
end
// 新增的配置
post_install do |installer|
flutter_post_install(installer) if defined?(flutter_post_install)
end
继续pod install 第二次报错：
[!] CocoaPods could not find compatible versions for pod "Flutter":
In Podfile:
Flutter (from `../flutter_module/.ios/Flutter`)
Specs satisfying the `Flutter (from `../flutter_module/.ios/Flutter`)` dependency were found, but they required a higher minimum deployment target.
处理方法：
修改原生Podfile文件里的Platform的版本号 和 flutter中iOS下Flutter.podspec文件中的ios.deployment_target 版本号一致！
若果Flutter module中不包含 Flutter.podspec ，则直接把IOS 原生项目中的支持版本号改成Podfile 中的一致
flutter_application_path = '../flutter_module'
load File.join(flutter_application_path,'.iOS','Flutter','podhelper.rb')
platform :ios, '12.0'//这里的版本号！和下图中ios.deployment_target 版本号一致！
target 'NativeDemo' do
install_all_flutter_pods(flutter_application_path)
use_frameworks!
# Pods for NativeDemo
end
post_install do |installer|
flutter_post_install(installer) if defined?(flutter_post_install)
end
pod install 成功后，编译项目第三次报错 ：
Sandbox: rsync.samba(30002) deny(1) file-write-create /Users/zhangfan/Library/Developer/Xcode/DerivedData/NativeDemo-csscysefpzumudflovqmzgvixwno/Build/Products/Debug-iphonesimulator/Flutter.framework
处理方法：
1.Xcode targets 里面 buildsettings 搜索 User Script Sanboxing 改为 NO
新版本的Xcode 15 编译报该错误 右侧[工具栏]项目的workspace 和 pod的 space 都选择为15.0 即可.
四、开发调试
1、 IOS 原生端代码 ，Appdelgate 中引入#import <Flutter/Flutter.h> 头文件,Appdelgate 中添加FlutterEngine 属性，m文件中初始化
2、 在项目中创建 FlutterDemoViewController 控制器，用来显示和处理和Flutter页面交互等相关逻辑，作用是原生跳转Flutter 入口
.m 文件中编写测试代码
#import "FlutterDemoViewController.h"
#import <Flutter/Flutter.h>
#import "AppDelegate.h"
@interface FlutterDemoViewController ()
@end
@implementation FlutterDemoViewController
- (void)viewDidLoad {
[super viewDidLoad];
UIButton * btn = [[UIButton alloc]initWithFrame:CGRectMake(100, 100, 100, 40)];
[btn setTitle:@"打开Flutter" forState:UIControlStateNormal];
[btn setTitleColor:UIColor.orangeColor forState:UIControlStateNormal];
[btn addTarget:self action:@selector(clickAction) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
-(void)clickAction {
[self project2];
}
//方案二
-(void)project2 {
FlutterEngine *flutterEngine = ((AppDelegate *)[[UIApplication sharedApplication] delegate]).flutterEngine;
FlutterViewController * flutter = [[FlutterViewController alloc] initWithEngine:flutterEngine nibName:nil bundle:nil];
//设置路由和参数
[flutter pushRoute:@"/my_flutter_page"];
[self.navigationController pushViewController:flutter animated:YES ];
}
1. 运行IOS 项目，效果如下：
OK，收工👌🏻
