Did not record an invocation in OCMStub/OCMExpect/OCMReject-CodePudding

I'm trying to mock a Singleton class in one of my unit tests. The way I'm creating my mock is like this:

MySingletonController *mockController = OCMClassMock([MySingletonController class]);
OCMStub([MySingletonController sharedController]).andReturn(mockController);

The complete error that I got is:

Did not record an invocation in OCMStub/OCMExpect/OCMReject.
Possible causes are:
- The receiver is not a mock object.
- The selector conflicts with a selector implemented by OCMStubRecorder/OCMExpectationRecorder. (NSInternalInconsistencyException).

One important thing to mention is that the shared instance is not something that instantiates the class, it just returns a variable. That variable is assigned during the init (which occurs) during the nib load. But I really doubt that this has something to do with the problem.

I'm not completely aware of what could cause the OCM error that I'm seeing.

The second line should be as follows:

OCMStub([mockController sharedController]).andReturn(mockController);

The problem is how I was declaring the OCMStub. My sharedController method is a class method. Then it needs to be declared differently for OCMStub.

MySingletonController *mockController = OCMClassMock([MySingletonController class]);
OCMStub(ClassMethod([(id)mockController sharedController])).andReturn(mockController);

After changing my code as above, the test started to work properly.
