You can't easily determine what image is inside your " UIButton " but since you're setting that image by state, just check the state property of the button.

Then you'll know which image you are using.

It can be as easy as:

if( playpauseButton.state == UIControlStateSelected )
    NSLog( @"Here I am using pause.png");

or, if you're doing this inside an action:

- (IBAction) buttonPushed: (id) sender
{
    UIButton * theButton = (UIButton *) sender;
    if(theButton)
    {
        if( theButton.state == UIControlStateSelected )
            NSLog( @"Here I am using pause.png");
    }
}
