Make image scroller in iphone

In this  tutorial you will learn about scrolling images horizontally. from scroller when you will select any image that will become large..
Classes.
ScrollView .h

#import <Foundation/Foundation.h>
@interface ScrollView : UIScrollView {
}
@end

ScrollView .m 

#import "ScrollView.h"
@implementation ScrollView
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.nextResponder touchesBegan:touches withEvent:event];
}
@end

ScrollViewController .m

#import <UIKit/UIKit.h>
#import "ScrollView.h"
@interface ScrollViewController : UIViewController <UIScrollViewDelegate> {
IBOutlet ScrollView *scrollView;
IBOutlet UIImageView *imageView;
NSMutableArray *images;
NSArray *imagesName;
}
-(void)ShowDetailView:(UIImageView *)imgView;
@end

ScrollViewcontroller.m

#import "ScrollViewController.h"

@implementation ScrollViewController
// The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization.
imagesName = [[NSArray alloc]initWithObjects:@"Icon-Small.png",@"Icon.png",@"BubbleRighthand.png",@"Icon-Small-50.png",
 @"Bubblelefthand.png",@"iTunesArtwork",nil];
images = [[NSMutableArray alloc]init];
    }
    return self;
}


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
scrollView.delegate = self;
scrollView.scrollEnabled = YES;
int scrollWidth = 120;
scrollView.contentSize = CGSizeMake(scrollWidth,80);
int xOffset = 0;
imageView.image = [UIImage imageNamed:[imagesName objectAtIndex:0]];
for(int index=0; index < [imagesName count]; index++)
{
UIImageView *img = [[UIImageView alloc] init];
img.bounds = CGRectMake(10, 10, 50, 50);
img.frame = CGRectMake(5+xOffset, 0, 160, 110);
NSLog(@"image: %@",[imagesName objectAtIndex:index]);
img.image = [UIImage imageNamed:[imagesName objectAtIndex:index]];
[images insertObject:img atIndex:index];
scrollView.contentSize = CGSizeMake(scrollWidth+xOffset,110);
[scrollView addSubview:[images objectAtIndex:index]];
xOffset += 170;
}
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch * touch = [[event allTouches] anyObject];
for(int index=0;index<[images count];index++)

NSLog(@"x= %f,y=%f",[touch locationInView:self.view].x,[touch locationInView:self.view].y) ;
if(CGRectContainsPoint([imgView frame], [touch locationInView:scrollView]))
{
[self ShowDetailView:imgView];
break;
}
}
}
-(void)ShowDetailView:(UIImageView *)imgView
{
imageView.image = imgView.image; }
/*
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations.
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
*/
- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];
   
    // Release any cached data, images, etc. that aren't in use.
}
- (void)viewDidUnload {
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (void)dealloc {
[images release];
[imagesName release];
    [super dealloc];
}
