Dots don't disappear on a single page

[killer1loop]

I'm implementing DD Page Control, but I have an issue regarding hiding the control when only one page is displayed. I have imported the DDPageControl class, and added to the main view controller the following code:

int numberOfPages = 1;

dotsControl = [[DDPageControl alloc] init] ;
[dotsControl setHidesForSinglePage:YES];
[dotsControl setCenter: CGPointMake(self.view.center.x, self.view.bounds.size.height-20.0f)];
[dotsControl setAutoresizingMask:UIViewAutoresizingFlexibleBottomMargin];
[dotsControl setNumberOfPages: numberOfPages];
[dotsControl setCurrentPage:0] ;
[dotsControl setDefersCurrentPageDisplay: YES] ;
[dotsControl setType: DDPageControlTypeOnFullOffEmpty] ;
[dotsControl setOnColor: [UIColor colorWithRed:(250.0/255.0) green:(170.0/255.0) blue:(0.0/255.0) alpha:1.0]] ;
[dotsControl setOffColor: [UIColor colorWithWhite: 0.7f alpha: 1.0f]] ;
[dotsControl setIndicatorDiameter: 7.0f] ;
[dotsControl setIndicatorSpace: 7.0f] ;

[self.view insertSubview:dotsControl belowSubview:thumbnailControl];

but dots are always drawed also on views of only 1 page
