Compiler got confused about layout
I am using OCMock to assist with testing developed for iPad apps using Xcode. I have a test code:
id mock = [OCMockObject mockForProtocol:@protocol(SomeProtocol)];
Vector direction = { 1.0f, 2.0f, 3.0f };
[[mock expect] setDirection:direction];
When I try to compile I get warnings and errors like this:
warning: multiple methods named 'setDirection:' found
error: sending 'Vector' to parameter of incompatible type
'UISwipeGestureRecognizerDirection' (aka 'enum UISwipeGestureRecognizerDirection')
Obviously, the compiler cannot determine what type of object the layout should be. I'm not sure how to specify that it should deal with the setDirection method from the SomeProtocol protocol instead of the setDirection method from another class.
What can you do to successfully create a test case like this assembly?
By ditching the layout with the act, it will remove the ambiguity:
[(id<SomeProtocol>)[mock expect] setDirection:direction];
For modern OCMock 3 syntax:
id protocolMock = OCMProtocolMock(@protocol(MYProtocol));
OCMExpect([(id <MYProtocol>)protocolMock ambiguousMethod]);
