Question

I am trying to mockj a segmented control and I am getting crashes, any suggestions?

NSInteger selectedSegment = 2;
id segmentedControlMock = [OCMockObject niceMockForClass:[UISegmentedControl class]];
[[[segmentedControlMock stub] andReturn:OCMOCK_VALUE(selectedSegment)] selectedSegmentIndex];

I get a crash as soon as i call selectedSegmentIndex on my mock object:

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘Expected invocation with object return type.’

You need to use andReturnValue:

NSInteger selectedSegment = 2;
id segmentedControlMock = [OCMockObject niceMockForClass:[UISegmentedControl class]];
[[[segmentedControlMock stub] andReturnValue:OCMOCK_VALUE(selectedSegment)] selectedSegmentIndex];
