组件化遇到的问题

        来公司大半年时间了,一个人搞组件化不轻松,先来看看podfile,业务功能都已经拆分成了一个组件,现在主工程就是一个空壳子,所有的业务场景都在组件化包里面。现在总结一下,在组件化过程中遇到的问题。

    source 'https://git.XXX.com/products/paas-app-ios-spec.git'
    source 'https://github.com/CocoaPods/Specs.git'
    # platform :ios, '8.0'
    
    target 'YYPaas' do
    pod 'PaasBaseComponent', '~> 1.0.30'
    
    #pod 'PaasUMComponent', '~> 1.0.1'
    pod 'PaasAddressComponent', '~> 1.0.7'
    pod 'PaasThemeBuildStyleComponent', '~> 1.0.1'
    pod 'PaasUMBuildStyleComponent', '~> 1.0.15'
    pod 'PaasCollectionComponent', '~> 1.0.1'
    pod 'PaasFootprintComponent', '~> 1.0.2'
    pod 'PaasIntegralComponent', '~> 1.0.4'
    pod 'PaasUserInfoComponent', '~> 1.0.1'
    pod 'PaasSettingComponent', '~> 1.0.3'
    pod 'PaasOrderComponent', '~> 1.0.5'
    pod 'PaasAfterSaleComponent', '~> 1.0.1'
    
    
    #use_frameworks!
    
    # Pods for YYPaas
    

    创建私有库没有通过远端校验问题

    pod spec lint --sources='https://git.xxxx.com/products/paas-app-ios-spec.git,https://github.com/CocoaPods/Specs' --use-libraries --allow-warnings --verbose
    

        一般创建私有库的时候,本地校验都能通过,但是远端校验通不过,报错下图的错误


    pod spec lint 报错.png

        上网查原因是上传的包过大,http的头部错误导致。后来修改postBuffer改为50M,100M都,但是还是不起作用。后来通过修改私有库的.podspec文件来解决这个问题。

        本地校验指定source路径为https

    s.source           = { :git => 'https://git.xxx.com/yuyi/PaasAddressComponent.git', :tag => s.version.to_s }
    

        提交代码至远端后修改sourcessh方式,然后进行pod spec lintpod repo push

    s.source           = { :git => 'ssh://git@git.xxx.com:3589/yuyi/PaasAddressComponent.git', :tag => s.version.to_s }
    

        pod repo push 操作后要记住把s.source的引入方式改为https,不然通过不了本地校验。
        私有库都托管到公司的gitlab上面,现在还没有解决这个问题,我想应该是公司gitLab设置的问题,毕竟在同样的私有库托管在https://gitee.com/或者自己的gitlab账号都没有出现过同样的问题。

    资源文件的引用问题

        搭建页面的时候都是用Masonry代码布局,没有用xib文件。这里的资源文件自剩下图片资源了。
        假如不在组件中,图片资源交给Assets.xcassets来管理,引用直接通过[UIImage imageNamed:@"paas_nodata_placeholder"]
        现在没有单独的组件包的图片资源就不会放在Assets.xcassets,而是通过放在组件Assets目录下来管理,引用方式也变成了[UIImage imageWithContentsOfFile:path]

    + (UIImage *)imageWithPaasComponentType:(PaasComponentType)type
                              WithClassName:(Class)className
                                   WithName:(NSString *)imageName
    {
        NSBundle * bundle = [NSBundle bundleForClass:className];
        NSString * componentName;
        switch (type) {
            case PaasComponentType_Base:
                componentName = @"PaasBaseComponent";
                break;
            case PaasComponentType_UM:
                componentName = @"PaasUMComponent";
                break;
            case PaasComponentType_Address:
                componentName = @"PaasAddressComponent";
                break;
            case PaasComponentType_BuildUM:
                componentName = @"PaasUMBuildStyleComponent";
                break;
            case PaasComponentType_Collection:
                componentName = @"PaasCollectionComponent";
                break;
            case PaasComponentType_Footprint:
                componentName = @"PaasFootprintComponent";
                break;
            case PaasComponentType_Integral:
                componentName = @"PaasIntegralComponent";
                break;
            case PaasComponentType_UserInfo:
                componentName = @"PaasUserInfoComponent";
                break;
            case PaasComponentType_Setting:
                componentName = @"PaasSettingComponent";
                break;
            case PaasComponentType_Order:
                componentName = @"PaasOrderComponent";
                break;
            case PaasComponentType_AfterSale:
                componentName = @"PaasAfterSaleComponent";
                break;
            case PaasComponentType_Evaluation:
                componentName = @"PaasEvaluationComponent";
                break;
                
            default:
                break;
        }
        NSString * resource = [NSString stringWithFormat:@"%@.bundle/%@.png",componentName,[self addSuffixWithImageName:imageName]];
        NSString * path = [bundle pathForResource:resource ofType:nil];
        return [UIImage imageWithContentsOfFile:path];
    }
    
    + (NSString *)addSuffixWithImageName:(NSString *)imageName
    {
        NSString * fileName;
        if ([UIScreen mainScreen].scale == 3)
        {
            fileName = [NSString stringWithFormat:@"%@@3x",imageName];
        }
        else
        {
            fileName = [NSString stringWithFormat:@"%@@2x",imageName];
        }
        return fileName;
    }
    

        首先根据className来确定所在的Bundle,然后根据PaasComponentType来确定所在的组件名称,最后用[UIScreen mainScreen].scale来确定是用@2x图片还是@3x图片。

        podspec加入图片文件

    组件化图片引入方式.png
        s.resource_bundles = {
            'PaasAddressComponent' => ['PaasAddressComponent/Assets/*.png']
        }
    

    组件之间的通讯问题

        我在拆分订单组件和售后组件之前,订单详情是这样跳转到申请售后的

    RefundViewController * vc = [[RefundViewController alloc]init];
    vc.FmodelArray = self.modelArray
    [self.navigationController pushViewController:vc animated:YES];
    

        OrderShopGoodsModel是商品的modelself.modelArray是商品详情存放OrderShopGoodsModel的集合,RefundViewController对外暴露了一个FmodelArray数组,里面存放的是OrderShopGoodsModel集合。
        后来为了解耦,创建了RefundShopGoodsModelOrderShopGoodsModelRefundShopGoodsModel是没有任何区别的,都是用来存放商品的信息,例如 id、name、sku、imageUrl、price等。converRefundGoodsModelWithArray用来把OrderShopGoodsModel转化成RefundShopGoodsModel

    vc.FmodelArray = [self converRefundGoodsModelWithArray:self.modelArray];
    

        这样没有根本解决解耦问题,把转换Model的代码放在订单详情,订单详情还需要依赖RefundShopGoodsModel,同样把转换的代码放在申请售后,售后模块还要依赖OrderShopGoodsModel
        为了解决模块之间通讯的参数问题,是不能用Model来传递的,否则无法解决依赖问题。最后的做法是RefundViewController暴露出一个字典Fparams用来接收参数。Fparams是未经转化原始商品数据。然在RefundViewController内写方法将字典转为相应的模型。

    vc.Fparams = self.refundParams;
    

        配合中间件CTMediator路由跳转如下

    UIViewController * vc = [[CTMediator sharedInstance] CTMediator_RefundViewControllerWithValue:self.refundParams];
    [self.navigationController pushViewController:vc animated:YES];
