Memory Problem when used as background for UIPageViewController

[Kaitis]

Hi, I am trying to use your class as the background of the child/content view controller of a UIPageViewController. The problem I am having is that with every new page generated the memory goes up, and up. (from what I understand the size of the image is added to the memory every time but never released). Do you think this might be a problem with your class or am I doing something wrong with the pageViewController?

Here is the code I am using

• (void)viewDidLoad {
  [super viewDidLoad];

  //KEN BURNS

  NSString *filepath = [[NSBundle mainBundle]pathForResource:self.imageString ofType:@"png"];
  NSLog(@"Loading Ken View with image %@",filepath);

  self.kenView.frame = self.view.frame;

  [self.kenView animateWithImagePaths:@[filepath] transitionDuration:8 loop:YES isLandscape:YES] ;

}
-(void)viewWillDisappear:(BOOL)animated{
[self.kenView stopAnimation];
}

• (void)viewDidDisappear:(BOOL)animated
  {

  [super viewDidDisappear:animated];
  [self setKenView:nil];
  }

I would really appreciate it if you can help me out!
Thanks
