What's the best way to call an IBAction from with-in the code?

Question

Say for instance I have an IBAction that is hooked up to a UIButton in interface builder.

- (IBAction)functionToBeCalled:         


        

Answer 1

The proper way is either:

- [self functionToBeCalled:nil] 

To pass a nil sender, indicating that it wasn't called through the usual framework.

OR

- [self functionToBeCalled:self]

To pass yourself as the sender, which is also correct.

Which one to chose depends on what exactly the function does, and what it expects the sender to be.
