I’ve been trying to TDD an app that uses GLKit using the Kiwi test
framework. One of the methods I’m stubbing returns a GLKMatrix4. I stub it
like this:
PhysicsManager *mockManager = [PhysicsManager mock];
>
[mockManager stub:@selector(physicsTransformForObject:)
> andReturn:theValue(GLKMatrix4Identity)];
When that code executes, it tries to encode the type of GLKMatrix4 and I
get this error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException',
> reason: '+[NSMethodSignature signatureWithObjCTypes:]: unsupported type
> encoding spec '(' in '(_GLKMatrix4={?=ffffffffffffffff}[16f])8@12''
I’m not too familiar with NSMethodSignature; is this something I could get
around fairly easily? My current approach is going to be to box GLKMatrix4
into an object (probably NSValue) and use that instead, but I would be
interested to be able to fix it in Kiwi if possible.
