iPhone/Objective C: How can I get the UIButton instance from NIB

I placed 1 UIButton on nib, and when user click this button,an IBAction method connect to it with a Status param.

What I want is, user click button and pass the Status to the IBAction method, and in that method, I need access the instance of the button.

How can I get the button's instance without an (id) sender here?

You can wire up the UIButton with an outlet like you did with your IBAction to connect it.

In your header add:

UIButton *myButton;

...

@property (nonatomic, retain) IBOutlet UIButton *myButton;

And then link the new outlet with your button in IB.

Then you can access the button with myButton in your instance.

Why without (id) sender? And what do you mean by that anyway? The sender argument of the action method is a reference to the button's instance. All you have to do is cast it to the proper type:

UIButton *button = (UIButton *)sender;

- (IBAction)buttonPress:(id)sender
{
 UIButton *button = (UIButton *)sender;
// button is the instance of your button

}
