Does your code look like this?

@interface myViewController : UIViewController {
    UIBUtton *myButton;
}
@property (nonatomic, retain) IBOutlet UIButton *myButton

@end;

@implementation myViewController

@synthesize myButton;

- (void) someMethod
{
    //Use myButton Here?
    CGRect r = myButton.frame;
}

@end

Or This:

@interface myViewController : UIViewController {
    // No need to declare myButton for iPhone or Mac 64-bit
}
@property (nonatomic, retain) IBOutlet UIButton *myButton

@end;

@implementation myViewController

@synthesize myButton;

- (void) someMethod
{
    //Use myButton Here?
    CGRect r = self.myButton.frame;
}

@end

if it's the latter, myButton isn't the private variable - only the property.
