title: Date from NSDate is null after converting
body: <p>I need to convert String as a date and then preset it in a UILabel. When I do this like below, I get null string and the UILabel is also null. What is wrong in this code?</p>
  
  <pre><code>NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
   [dateFormat setDateFormat:@"MMMM dd, YYYY HH:mm:ss"];
  
   NSDate *dateFromString;
   dateFromString = [dateFormat dateFromString:[tmpDevice valueForKey:@"date"]]; //This string is from array of object and is not null
  
       NSString *stringFromDate  = [dateFormat stringFromDate:dateFromString];
  
       NSLog(@"%@", stringFromDate); // here is null
  
       [cell.dateOfAddedCell setText: stringFromDate]; // and here also is null
  </code></pre>
