App间的唤起和通信

App跳转

·使用URL Scheme支持App启动、跳转及参数传递

·分享 / 登陆 / 拉起App Store等

设置URL Type

 

在UIApplication中处理参数和业务逻辑

-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url 
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options{

    //业务处理

}

通过Scheme唤起其他App

通过Scheme判断App是否安装

使用UIApplication唤起App

//判断目标App是否安装
-(BOOL)canOpenURL:(NSURL *)url;


// 通过点击拉起TestApp
-(void)viewClicked{
    NSURL *openURL = [NSURL URLWithString:@"TestApp://"];
    BOOL canOpen = [[UIApplication sharedApplication] canOpenURL:openURL];
   
    [[UIApplication sharedApplication] openURL:openURL] 
                                       options:nil 
                                       completionHandler:^(BOOL success) {
    
    }];
}

Universal Link

·使用HTTP / HTTPS协议启动客户端

·Scheme重复 / Web和Native统一

·需要配合Web端进行注册

·在Safari / 微信 / 其他App中使用Universal Link

组件化

·组件化意义：

        ·适用于基础功能稳定、项目规模较大

        ·项目变大，编译时间长，基础模块的产品间复用

        ·多团队发布、集成、测试不便，协同开发相互依赖和冲突

·组件化拆分

        ·工具类 / 基础功能 / 基础UI控件 / 业务线 ...

·组件化通信选型

        ·常用的三种方案

                ·Target-Action

                        ·抽离业务逻辑

                        ·通过中间层进行调用

                        ·中间层使用runtime反射

                        ·中间层代码优化

                ·URL Scheme 

                        ·使用URL处理本地的跳转

                        ·通过中间层进行注册&调用

                        ·注册无需使用反射

                ·Protocol - Class

                        ·增加Protocol Wrapper层

                        ·中间件返回Protocol对应的Class

                        ·解决硬编码问题
