scrollView=[[UIScrollView alloc]init];

    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);

Solution 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);

Solution 2

"official" example created by Apple take a look at the StreetScroller Demo.

Solution 3

For the desired outcome that is shown in the picture, ie, the horizontal scroll, Use ScrollView instead of tableview.

set the pane of scroll to horizontal and dynamically create imageview inside a loop and insert images inside it

hope it helps :)
