  <p>I am trying to filter the array using the key UserId. But unable to filter. I tried in this way.</p>
  
  <pre><code>NSString* userId=userInfo[@"UserId"];
  NSPredicate* predicate=[NSPredicate predicateWithFormat:@"(UserId == %@)",userId];  NSArray* filteredArrays = [allData filteredArrayUsingPredicate:predicate];
  </code></pre>
  
  <p>Here UserId contains integer value in string format. Whie trying to filter using the provided code snippets ,
  It is always returning O objects.</p>
