title: How to get UIImage(ImageURL) height and width without converting to NSData
body: <p>In my project i need to show the different sizes of images in zig-zag fashion. so, i converted the uiimages(url) which are coming from service to <code>NSData</code> and then i get the uiimage. my code is </p>
  
  <pre><code>NSURL *url = [NSURL URLWithString:[[_result objectAtIndex:i ] valueForKey:@"PImage"]];
  
  NSData *data = [NSData dataWithContentsOfURL:url];
  
  UIImage *image = [UIImage imageWithData:data];
  </code></pre>
  
  <p>so i can get the image size(width and height), But my problem is according to the image size, i need to create <code>UIView</code>,  this code is works fine for me, but it is taking too much of time(almost 25 sec) to load 8 images. i figured converting <code>UIImage</code> to <code>NSData</code> is taking time. Is there any way to get the image size(width and height) without converting it into <code>NSData</code></p>
  
  <p>Thanks for spending time for me.</p>
