xcode architectures macro for detecting arm64 or armv7

Question

My project uses a third party framework (with some .a libraries).

And unfortunately the .a libraries I got only support 32bit device.

So I can compiles and install the app on my ipod touch5 through xcode.

But, I can not compiles and install the app on my iphone6 which is arm64.

So I want to comment out the codes use the .a libraries when I compile arm64 using some kind of macro like:

#if (ARCHITECTURES == ARMV7 || ARCHITECTURES == ARMV7S)
    // only when bit32 device
    ThirdPartyManager::getInstance()->initSDK();
#endif

I tried to google but can not find any macro that I might be able to use ...

Any suggestion will be appreciated thanks :)

Answer 1

The variable should be called ARCHS.

See this answer for more details about the more general question - how to get all build settings from the XCode:
