使用Xcode链接iOS静态库的正确变体

Question

I have an iOS static library.

As a matter of fact, I have four variants of it:

Debug-iphoneos/libopende.a
Debug-iphonesimulator/libopende.a
Release-iphoneos/libopende.a
Release-iphonesimulator/libopende.a

I want to link my iOS app against this static library using Xcode.

To do so, I go to Build Phases , and in Link Binary With Libraries , I click the '+' to add one, using Add Other .

Now I have the problem of which variant I should be adding. So I just pick one of the .a files, and hope Xcode is smart enough to find the others?

Anyways, if I do this, the linking fails saying it can't find libopende.a file.

So, is it even possible to do what I want, without first building a 'Framework' instead of a set of static libraries?

Ok, so when linking against a static iOS library, you need to know that:

1. It does not matter which .a file you add in the Build Phases - Link Binary With Libraries panel. Any of the four .a files will do, it only takes the file name, not its path.

2. To actually differentiate between library variants for Debug/Release Device/Simulator, you need to specify the correct library paths in the Build Settings - Library Search Paths .
