Say for instance I have an IBAction that is hooked up to a UIButton in interface builder.
- (IBAction)functionToBeCalled:(id)sender
{
// do something here
}
With-in my code, say for instance in another method, what is the best way to call that IBAction?
If I try to call it like this, I receive an error:
[self functionToBeCalled:];
But, if I try to call it like this (cheating a bit, I think), it works fine:
[self functionToBeCalled:0];
What is the proper way to call it properly?
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.
