Q:

Button down/up in objective c for iphone?

I have a button, and I'd like to call a function when the user pushes it then call a different function when he releases it.
Right now I'm using this to create the button:
[ScanButton addTarget:self action:@selector(scanButtonPressed) 
 forControlEvents:UIControlEventTouchUpInside];

to call scanButtonPressed. As of now scanButtonPressed is only called upon release. How do I change this?
Thanks

A:

How about by trying a control event other than UIControlEventTouchUpInside?
