title: UIScrollView initial offset
body: <p>I have created a UIScrollView using storyBoard. I wanted to add few labels and buttons in that. At very first time, when I add label using following method it is not visible. </p>
  
  <pre><code>int _x=0,_y=0;
  UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(_x,_y, stringsize.width, stringsize.height)];
  </code></pre>
  
  <p>But, When I set _y position as -62 then it is visible as expected. </p>
  
  <p>I have tried to invoke following methods before adding label to UiScrollView to fix this issue. But nothing works. </p>
  
  <pre><code>[scrollview.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
  scrollview.contentSize = CGSizeMake(scrollview.frame.size.width, 0);
  [scrollview setContentOffset:CGPointMake(0, 0) animated:YES];
  </code></pre>
  
  <p>Basically the issue is during first time launch of UIscrollView the Y position is not set properly. </p>
