How to get caller if the function has no -sender parameter?

Question

For example, there are functions named -(void)Foo, and -(void)Foo:(id)sender.

The -(void)Foo:(id)sender can get the caller from parameter, and my question is, how to get caller from -(void)Foo? Is there any way to get the caller?

You have different objects that are calling your - (void)foo? — Alex Terente, May 20 '11 at 08:15

Please have a look at Objective C find caller of method. For what do you need it? The (id)sender parameter is passed directly by the method sending the message, there is no magic involved.

Thank you any way. Because a custom control doesn't pass the self as the sender parameter, so I cannot get some information from the custom control. I will find another way to solve the problem. – AechoLiu May 20 '11 at 08:30
