Question

I am trying to create sample gallery before filling real data.

    float xAxis = 0;
    float mostHeight = self.galleryView.bounds.size.height;
    for (int i = 0; i < 5; i++) {

        //getImage from url
        UIImage* myImage = [UIImage imageWithData: 
                            [NSData dataWithContentsOfURL: 
                             [NSURL URLWithString: @"http://4.bp.blogspot.com/-M9k3fhlUwmE/TdYgxL97xMI/AAAAAAAAAY8/_r45zbAm1p0/s1600/CARTOON_Cat-full.jpg"]]];
        myImage = [[MyMath sharedMySingleton] imageWithImage:myImage convertToSize:CGSizeMake(mostHeight - 10, mostHeight - 10)];
        //set image
        UIImageView *rview= [[UIImageView alloc] initWithImage:myImage];
        /*adding the view to your scrollview*/
        [self.galleryView addSubview:rview];
        xAxis += myImage.size.width + 20;
    }
    //set scrolling area
    self.galleryView.contentSize = CGSizeMake(xAxis, mostHeight);

galleryView is UIScrollView from xib. Here, i am trying to fill 5 same pictures to gallery, but it fills only one and space after that (because of xAxis number). What did i do wrong?

P. S. I am new in iPhone sdk, so don’t judge me

You never set the frame for the UIImageView. You need to offset the x coordinate of the origin of the frame (frame.origin.x) by width of the image view + padding.
