iOS制作通用库-适用于i386和arm7 [英] iOS making a universal library - for i386 and arm7

问题描述

我们正在建立一个用于iOS开发的库.我们可以为模拟器生成i386库，或者为硬件设备生成arm7库.现在，将库分发给其他开发人员时，我们需要具有两个不同的文件(.a库).出于分发目的，这有点麻烦.我在想;有没有一种方法可以在XCode中构建该库，以便单个.a库文件中同时包含i386和arm7，因此我们可以仅为i386和arm7两种体系结构分发一个库文件.

We are building a library for use in iOS development. We can generate either a i386 library for the simulator, or a arm7 library for the hardware device. As it is now, we need to have two different files (.a libraries) when distributing the library to our other developers. This is a little bit cumbersome for distribution purposes. I was wondering; is there a way to build the library in XCode so that a single .a library file has both i386 and arm7 in it, so that we can distribute just a single library file for both architectures i386 and arm7.

推荐答案

您可以使用lipo工具将这两个文件缝合为一个通用"文件:

You can use the lipo tool to stitch those two files into a single "universal" file:

lipo -create <i386_lib>.a <armv7_lib>.a -output lib.a
