Create a native plug-in for iOS and import it into your Unity project.

Define an extern method

For each native function you want to call, define an extern method in the C# file as follows:


[DllImport ("__Internal")]    private static extern float FooPluginFunction();

If using C++ (.cpp) or Objective-C++ (.mm) to implement your plug-in, declare functions with C linkage to avoid issues with name mangling:


extern "C" {  float FooPluginFunction();}

Plug-ins written in C or Objective-C don't need this, because these languages don't use name mangling.

Add your native code source files to the Unity Project's

Assets

Folder.

To configure plug-in settings for iOS:

Select the plug-in and view it in the
Inspector
?
.
In the Select platforms for plugin section, enable iOS.
In the Platform settings section, set CPU to the CPU architecture for your plug-in.
Select Apply.
