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);

Instead of using table view why don't you user UICollectionView with their delegates.

you can refer this - Creating a UICollectionView programmatically

It's best way to achieve your requirement.

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 :)
