title: Byte Array to NSData
body: <p>In a WebService JSON response is coming. In the response, there is image is coming as a byte array. I have to show the image in a UIImageView. I am trying to convert the byte array to NSData. But not getting how to do that. Any help would be appreciated.
  I am confident that the byte array has image data in it.
  Sample Byte array for your reference:</p>
  
  <pre><code>        (137,
          80,
          78,
          71,
          ...
          66,
          96,
          130)
  </code></pre>
  
  <p>Thanks</p>
