        [imagesarray addObject:dataimages];


     }

scrollView=[[UIScrollView alloc]init];

    scrollView.delegate = self;
    scrollView.scrollEnabled = YES;
    int scrollWidth = 100;
    scrollView.contentSize = CGSizeMake(scrollWidth,100);
    scrollView.frame=CGRectMake(0, 0, 320, 100);
    scrollView.backgroundColor=[UIColor yellowColor];

    [self.view addSubview:scrollView];

    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]];

Answer 1

your coding is Fine, but you are assign the value of [scrollView addSubview:[images objectAtIndex:index]];, this is not the fine one, I modify your code, as per your result Want

UIScrollView  *scrollVie=[[UIScrollView alloc]init];

scrollVie.delegate = self;
scrollVie.scrollEnabled = YES;
int scrollWidth = 100;
//scrollVie.contentSize = CGSizeMake(scrollWidth,100);
scrollVie.frame=CGRectMake(0, 51, self.view.frame.size.width, 100);
scrollVie.backgroundColor=[UIColor redColor];




int xOffset = 0;

for(int index=0; index < [imagesarray count]; index++)
{

    UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(xOffset,10,160, 110)];
    img.image = (UIImage*) [imagesarray objectAtIndex:index];

    [scrollVie addSubview:img];

    xOffset+=100;


}

[self.view addSubview:scrollVie];

scrollVie.contentSize = CGSizeMake(scrollWidth+xOffset,110);
