I think the problem is that you're trying to invoke a mock object directly. For what you're trying to do, you shouldn't need a mock object. Just call the method and verify that the image was set:

expect(myObject.imageView.image).to.beNil();
[myObject do_something_that_calls_setImage];
expect(myObject.imageView.image).not.to.beNil();

If you really want to use a mock for some reason, you could do it with a real UIImageView and a partial mock:

UIImageView *imageView = myObject.imageView;
id mockView = [OCMockObject partialMockForObject:imageView];
__block BOOL imageSet = NO;
[[[mockView stub] andDo:^(NSInvocation *invocation) {
      UIImage *img;
      [invocation getArgument:&img atIndex:2];
      imageSet = (img != nil);
  }] setImage:OCMOCK_ANY];

[myObject do_something_that_calls_setImage];
expect(imageSet).to.beTruthy();
