title: Problems with cropping a UIImage in Swift
body: <p>I'm writing an app that takes an image and crops out everything except for a rectangle in the center of the image. (SWIFT) I can't get the crop function to work though. This is what I have now:</p>
  
  <pre><code>func cropImageToBars(image: UIImage) -&gt; UIImage {
       let crop = CGRectMake(0, 200, image.size.width, 50)
  
       let cgImage = CGImageCreateWithImageInRect(image.CGImage, crop)
       let result: UIImage = UIImage(CGImage: cgImage!, scale: 0, orientation: image.imageOrientation)
  
       UIImageWriteToSavedPhotosAlbum(result, self, nil, nil)
  
       return result
    }
  </code></pre>
  
  <p>I've looked at a lot of different guides but none of them seem to work for me. Sometimes the image is rotated 90 degrees, I have no idea why it does that.</p>
