title: Converting int to NSString
body: <p>I thought I had nailed converting an <code>int</code> to and <code>NSString</code> a while back, but each time I run my code, the program gets to the following lines and crashes. Can anyone see what I'm doing wrong?</p>
  
  <pre><code>NSString *rssiString = (int)self.selectedBeacon.rssi;
  UnitySendMessage("Foo", "RSSIValue", [rssiString UTF8String] );
  </code></pre>
  
  <p>These lines should take the rssi value (Which is an NSInt) convert it to a string, then pass it to my unity object in a format it can read. </p>
  
  <p>What am I doing wrong?</p>
