title: Why NSLog print like these?
body: <p>Line of Code:</p>
  
  <pre><code>@interface ViewController (){
  IBOutlet UILabel *lbl_FirstName;
  IBOutlet UILabel *lbl_LastName;
  
  }
  
  @implementation ViewController
  
  - (void)viewDidLoad
  {
  [super viewDidLoad];
  
  lbl_FirstName.text=@"XFirst";
  lbl_LastName.text=@"XLast";
  
  NSLog(@"First Name: %@",lbl_FirstName.text);
  NSLog(@"Last Name: %@ %@",lbl_LastName.text);
  
  }
  </code></pre>
  
  <p>Result:</p>
  
  <pre><code>First Name: XFirst
  Last Name: (null) XLast
  </code></pre>
  
  <p>Problem:
    *    Why 2nd NSLog statement print like these? </p>
  
  <p>I know the reason of (null), because i didn't give any reference for the lbl_Lastname in my .xib. But I don't know the reason of print after (null). </p>
