                NSURL * urlone=[NSURL URLWithString:imageString];

    NSData *datanew =[NSData dataWithContentsOfURL:urlone];

    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)];

    [imageView setImage:[UIImage imageWithData:datanew]];

NSMutableArray *arr=[[NSMutableArray alloc] init];
NSString *urlString=[NSString stringWithFormat:@"http://ielmo.xtreemhost.com/array.php"];

NSURL * url=[NSURL URLWithString:urlString];

NSData *data =[NSData dataWithContentsOfURL:url];

NSError *error;

NSMutableArray *json=(NSMutableArray*)[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];

NSLog(@"%d",[json count]);

NSLog(@"%@",[json objectAtIndex:0]);
NSString *imageString;
for (int i=0; i<[json count]; i++) {
     imageString=[NSString stringWithFormat:@"%@",[json objectAtIndex:i]];
    [arr addObject:imageString];
}

NSLog(@"%@",arr);
// NSString *imageString=[NSString stringWithFormat:@"%@",[json objectAtIndex:0]];

 NSURL * urlone=[NSURL URLWithString:imageString];

 NSData *datanew =[NSData dataWithContentsOfURL:urlone];

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)];

[imageView setImage:[UIImage imageWithData:datanew]];

UIView *  testView = [[UIView alloc] initWithFrame:CGRectMake(30.0f, 300.0f, 300.0f, 200.0f)];

[testView addSubview:imageView];

[self.view addSubview:testView];

Could you explain what in the code you have posted is an answer to the problem happening here, so that the user and future readers can learn from it? — Andrew Barber, Apr 15 '14 at 18:27

After parsing JSON response use follow code

UIScrollView *testView = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,320,480)];
for(int i=0; i<[json count]; i++){
NSLog(@"%@",[json objectAtIndex:i]);
NSString *imageString=[NSString stringWithFormat:@"%@",[json objectAtIndex:i]];
NSURL * urlone=[NSURL URLWithString:imageString];
NSData *datanew =[NSData dataWithContentsOfURL:urlone];*
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,i*480,320,480)];
[imageView setImage:[UIImage imageWithData:datanew]];
[testView addSubview:imageView];
}
[self.view addSubView:testView];

*Note: Now you are going with Synchronous Request to download & load images in the view. It is not a good approach. Use Asynchronous requests for downloading images and loading them.

Find the following URL for asynchronous image downloading

you can get an image dictionary into array like this, into data object Suppose i have PostClubDC class with posDC obj

 for(NSDictionary *returnDicto in dataArray)
        {
            PostClubDC *postDC = [[PostClubDC alloc] init];
            NSDictionary * returnDict = [returnDicto objectForKey:@"club_info"] ;
            postDC.postID = [[returnDict objectForKey:@"Id"]integerValue];
            postDC.postName = [returnDict objectForKey:@"name"];
            postDC.postImage = [returnDict objectForKey:@"image"];

            [yourDataArray addObject:postDC];
        }
