OCMStub mocking a class method not working

[marcuswu0814]

I try to mocking a class method like this:

id classMock = OCMClassMock([NSString class]);
OCMStub([classMock string]).andReturn(@"123456");
NSString *aString = [NSString string];
NSLog(@"%@", aString);

But the aString is not "123456", anything wrong when I used it?

Sorry, I think I do it in wrong way.

I read the doc write: _Class methods on NSString and NSArray cannot be stubbed or verified_ Please help me to close this issue, thanks.
