OCMock 3: Text field mocking fails in strange ways

[patrickhartling]

I encountered an unexpected problem where simply creating a partial mock of an instance of UITextField contained within an other object results in this error if ‑resignFirstResponder is sent to the UITextField object:

-[OCMockTextFieldTest testCreateMock] failed: -[UITextInputTraits resignFirstResponder]: unrecognized selector sent to instance 0x102b05ba0

That was produced by running the test class I created to show the issue. I don't know the significance of this, but if the test method is written as follows, no error occurs:

- (void)testCreateMock
{
    UITextField *const textField = [UITextField new];
    id mockObject = OCMPartialMock(textField);
    [textField resignFirstResponder];
}

With the recent changes made in response to some of the other issues reported this problem seems to have been fixed, too. Could you retry whether it works for you now?

This issue still happens as of 8d323b3.

It may be an issue with UITextField not being KVC-compliant. See http://stackoverflow.com/questions/6617472/why-does-valueforkey-on-a-uitextfield-throws-an-exception-for-uitextinputtraits for more details.
