XCode 4.5 UiScrollView issue

I'm trying to implement an UIScrollView with Page Control with an array of images. I used same piece of code of another project, but it doesn't work with Xcode 4.5. ScrollView frame properties are all 0 while debugging, but the scrollview Outlet is well connected. Images doesn't show in the scroll. It is really strange. I have observed that properties are not synthesized automatically like previous versions. Here is the code:

@interface dashboardViewController : UIViewController <UIScrollViewDelegate>{

    BOOL pageControlBeingUsed;

}

@property (strong, nonatomic) IBOutlet UIScrollView *scrollView;
@property (strong, nonatomic) IBOutlet UIPageControl *pageControl;

- (IBAction)changePage;

@end




   - (void)viewDidLoad
    {
        [super viewDidLoad];

        self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"fondo.jpg"]]];

        pageControlBeingUsed=NO;

        scrollView.delegate=self;

        [self buildScrollView];



        // Do any additional setup after loading the view.
    }

    -(void)buildScrollView{

        NSArray *imagesQueue = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"icoblog.png"], [UIImage imageNamed:@"icogaleria.png"], [UIImage imageNamed:@"icobio.png"], nil];

        for(int i = 0; i < imagesQueue.count; ++i) {

            UIImageView *image = [[UIImageView alloc] initWithImage:[imagesQueue objectAtIndex:i]];

            CGFloat xOrigin = i * (scrollView.frame.size.width);

            image.frame = CGRectMake(xOrigin, 0, scrollView.frame.size.width, scrollView.frame.size.height);

            [scrollView addSubview:image];

            image=nil;


        }

        scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * imagesQueue.count, self.scrollView.frame.size.height);



}

Many thanks for your help.

Select your scrollview in the storyboard and untick the "auto layout" under file properties

Try pushing "self." infront of all the "scrollView" you don't have it.
