Add Multiple Images to ScrollView with PageControll

This is the code that I use when setting up a UIScrollView to contain multiple images that can be scrolled through. It has PageControl which shows no. of image as well.

Call this method from your Desired method (viewDidLoad or  viewWillAppear)

-(void) setupScrollView

 {

    //add the scrollview to the view

    self.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0,

                                                                     self.view.frame.size.width,

                                                                     self.view.frame.size.height)];

    self.scrollView.pagingEnabled = YES;

    [self.scrollView setAlwaysBounceVertical:NO];

    //setup internal views

    NSInteger numberOfViews = 3;

    for (int i = 0; i < numberOfViews; i++) 

{

        CGFloat xOrigin = i * self.view.frame.size.width;

        // add PageControl

        self.pageControl = [[UIPageControl alloc] init];

        self.pageControl.frame = CGRectMake(xOrigin+120, 175, 90, 37);

        self.pageControl.numberOfPages = 5;

        self.pageControl.pageIndicatorTintColor = [UIColor blackColor];

        self.pageControl.currentPageIndicatorTintColor = [UIColor greenColor];

        self.pageControl.currentPage = i;

        UIImageView *image = [[UIImageView alloc] initWithFrame:

                              CGRectMake(xOrigin, 0,

                                         self.view.frame.size.width,

                                         self.view.frame.size.height)];

       image.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@",[imgArray objectAtIndex:i]]];      // imgArray is Array of Images

        image.contentMode = UIViewContentModeScaleToFill;

        [self.scrollView addSubview:image];

 }

    //set the scroll view content size

    self.scrollView.contentSize = CGSizeMake(self.view.frame.size.width *

                                             numberOfViews,

                                             self.view.frame.size.height);

    //add the scrollview to this view

    [self.view addSubview:self.scrollView];

}

Thnx & Regards
