title: passing NSString to UILabel using delegate method
body: <p>I made delegate to transfer back from one view controller to another a string.</p>
  
  <p>The onSave method:</p>
  
  <pre><code>-(void)onSave:(NSString*)nameValue{
      NSLog(@"onSave in father controller");
      self.NameValue.text = [[NSString alloc]initWithFormat:@"Name= %@",nameValue];
      NSLog(@"%@",nameValue);
      NSLog(@"%@",self.NameValue.text);
  }
  </code></pre>
  
  <p>The first NSLOG print nameValue (NSString) for example print: 123 and the second NSLOG print NameValue (UILabel) but print NULL!!</p>
