title: how to add two integer values in objective-c
body: <p>I have written the following code </p>
  
  <pre><code>NSString *a = @"TextField1.text";
  NSInteger b = [a integerValue];
  NSString *p = @"TextField2.text";
  NSInteger q = [p integerValue];
  _TextLable.text=[NSString stringWithFormat: @"%d", b+q];
  </code></pre>
  
  <p>its not adding up b and q always shows the result 0 in <code>_TextLable.text</code></p>
