Solution:1

I think I understand what your'e asking...

What you want to do is to resize UIImages.

UIImage* resizeImageToSize(UIImage* image, CGSize size)  {      UIGraphicsBeginImageContext(size);        CGContextRef ctx = UIGraphicsGetCurrentContext();        //Account for flipped coordspace      CGContextTranslateCTM(ctx, 0.0, size.height);      CGContextScaleCTM(ctx, 1.0, -1.0);        CGContextDrawImage(ctx,CGRectMake(0.0f, 0.0f, size.width, size.height), image.CGImage);        UIImage* scaled = UIGraphicsGetImageFromCurrentImageContext();        UIGraphicsEndImageContext();      return scaled;  }
