title: Create Byte array from NSMutableArray
body: <p>I want to create a Byte Array like this one;</p>
  
  <pre><code>   Byte UUID[] = {0xEB, 0xEF, 0xD0, 0x83, 0x70, 0xA2, 0x47, 0xC8, 0x98, 0x37, 0xE7, 0xB5, 0x63, 0x4D, 0xF5, 0x24};
  </code></pre>
  
  <p>But the problem here I am facing is, I need to fill all the elements in the above array programatically from a <code>NSMutableArray</code> that holds the values as below;</p>
  
  <pre><code>(
      0xEB,
      0xEF,
      0xD0,
      0x83,
      0x70,
      0xA2,
      0x47,
      0xC8,
      0x98,
      0x37,
      0xE7,
      0xB5,
      0x63,
      0x4D,
      0xF5,
      0x24
  )
  </code></pre>
  
  <p>I have tried with the integer values of each index but it is showing '/0' in the Byte Array.
  If anyone have any information regarding this please share.</p>
  
  <p>Thanks </p>
