安利一个小工具 用于分析 iOS 包大小

LinkMapAnalyzer

基于项目工程编译链接产生的 Linkmap 文件，分析项目中各个模块的大小。

使用时要确保项目的 Build Settings -> Write Link Map File 已置为YES。然后在Path to Link Map File表明的路径里找到自己工程生成的 LinkMap 文件

如 LinkMap 文件内容大致为

# Path: /Users/guomiaoyou/Library/Developer/Xcode/DerivedData/GAG-focyaelrlonzsogsgfnrfxjywimo/Build/Products/Debug-iphonesimulator/GAG.app/GAG
# Arch: x86_64
# Object files:

LinkMapAnalyzer 分析结果各个模块大小为：

@lynulzy 谢谢支持。

能够分析不止是静态 目标文件等大小就更棒了

[guomiaoyou7784]

@XuYanci 可以讲讲你的具体需求吗？或者在 github 上给我提 issue ，我会抽空解决的
