基礎(chǔ)構(gòu)想將現(xiàn)有的app維護(hù)好，以上一個(gè)版本的app為模版創(chuàng)建多個(gè)app給租戶使用

需求： 1.現(xiàn)有app 為模版 里面涉及的有關(guān)現(xiàn)有App的圖片字樣 要使用boundle包裝起來(lái)
并創(chuàng)建一個(gè)全局文件替換字樣
2.有關(guān)推送分享登陸模塊創(chuàng)建confige配置文件 使租戶可以使用自己的賬戶
3.因?yàn)榇罅孔鈶魺o(wú)須有高度自定義話的內(nèi)容所以初步模版不考慮配置不同的控件頁(yè)面樣式 只需要能替換appid icon name 和一些主題色就好

根據(jù)需求思考方案:可以簡(jiǎn)化開(kāi)發(fā)步驟 通過(guò)創(chuàng)建多個(gè)target創(chuàng)建大量相似項(xiàng)目 （可能可以使用腳本替換）

1.png

2.png

3.png

如圖步驟 你就可以生成2個(gè)包名不同的APP了
但是根據(jù)需求我們還需要查找出有關(guān)現(xiàn)有app的圖片文字進(jìn)行替換
以及有關(guān)推送分享登陸模塊創(chuàng)建confige配置文件 使租戶可以使用自己的賬戶

然后通過(guò) 讀取項(xiàng)目配置做差異化

之后通過(guò)讀取文件取得個(gè)性化定制
但是此方式圖片處理不是很好如果圖片過(guò)多較難處理
思路通過(guò)唐橋猿題庫(kù)的博客

在Xcode的一個(gè)項(xiàng)目中，可以允許建立多個(gè)編譯的target瑰艘，每個(gè)target代表著最終編譯出來(lái)的一個(gè)App文件是鬼，在每個(gè)target中，可以添加不同的編譯源文件和資源文件紫新。最終均蜜，通過(guò)我們?cè)诓煌瑃arget之間，修改其 Copy Bundle Resources 和 Compile Sources 配置芒率，使課程之間的差異性得到實(shí)現(xiàn)囤耳。我們具體的配置方案如下：

我們的每個(gè)課程的資源文件都具有相同的文件名，例如首頁(yè)背景都叫 HomeBackgroundBg.png 偶芍，由于每個(gè)課程背景不一樣紫皇，所以我們?cè)诠こ讨校恳粋€(gè)課程target下腋寨，通過(guò)修改Copy Bundle Resources，使其都配置有不同的（但是同名） HomeBackgroundBg.png 化焕。這樣的好處是萄窜，在代碼邏輯層面，我們可以完全不用處理課程間資源文件的差異性問(wèn)題撒桨。資源文件的差異性都是通過(guò)配置文件來(lái)保證的查刻。

對(duì)于文案一類的差別，我們通過(guò)修改Compile Sources凤类，使不同的課程有著不同的文案定義文件穗泵。通過(guò)這樣，我們使不同課程有了不同的文案谜疤。另外包括后臺(tái)網(wǎng)絡(luò)接口的差異性問(wèn)題佃延，統(tǒng)計(jì)項(xiàng)的差異性問(wèn)題现诀，也都是這樣處理的。

如此簡(jiǎn)易版的多target 相似項(xiàng)目也就又了一定的可行性
