Ios 从XCode项目中删除未使用的资源

我正在开发iOs应用程序，在这个应用程序中，我每天在应用程序设计上都有很大的变化，所以我的应用程序的代码将达到大约200 Mb。但在这段代码中，我有大量未使用的图像可用。所以我想从我的XCode项目中删除这些图像，这样我就可以减少我的项目代码大小

我使用了stackoverflow.com上已经给出的一些脚本，但我发现脚本删除使用过的图像也是不可靠的。 我还使用了名为“苗条”的应用程序。它真的很好，但它的试用版，所以我不能使用它更多

---

所以，请任何人建议我有效的方法（任何应用程序）删除未使用的图像从xCode项目

未使用将帮助您在xCode项目中查找未使用的资源

我在这里回答了一个类似的问题：

在此处添加相同的详细信息：

我创建了一个python脚本来标识未使用的图像：。它可以这样使用：

python3 unused_assets.py '/Users/DevK/MyProject' '/Users/DevK/MyProject/MyProject/Assets/Assets.xcassets'

以下是使用脚本的几个规则：

• 将项目文件夹路径作为第一个参数传递给资产是很重要的 文件夹路径作为第二个参数
• 假设所有图像都保存在Assets.xcsets文件夹中，并在swift文件或故事板中使用

第一版中的限制：

• 不适用于目标c文件

我将根据反馈，努力改进它，但是第一个版本对大多数人来说应该是好的

请找到下面的代码。代码应该是不言自明的，因为我已经为每个重要步骤添加了适当的注释

# Usage e.g.: python3 unused_assets.py '/Users/DevK/MyProject' '/Users/DevK/MyProject/MyProject/Assets/Assets.xcassets'
# It is important to pass project folder path as first argument, assets folder path as second argument
# It is assumed that all the images are maintained within Assets.xcassets folder and are used either within swift files or within storyboards
