title: changing frame of UIScrollview not working in iOS xcode
body: <p>I don't know what I am doing wrong here.</p>
  
  <p>I dragged out UIScrollView in IB, connected it to UIViewController.h</p>
  
  <pre><code>@property (strong, nonatomic) IBOutlet UIScrollView *scrollView;
  </code></pre>
  
  <p>in UIViewController.m</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
      _scrollView.frame = CGRectMake(0, 200, 300, 500);
      _scrollView.contentSize = CGSizeMake(300, 600);
      _scrollView.backgroundColor = [UIColor grayColor];
      NSLog(@"x-pos:%f y-pos:%f width:%f height:%f of uiscrollview", _scrollview.frame.origin.x, _scrollview.frame.origin.y, _scrollview.frame.size.width, _scrollview.frame.size.height);
  }
  </code></pre>
  
  <p>I get NSLog :</p>
  
  <pre><code>x-pos:0.000000 y-pos:200.000000 width:300.000000 height:500.000000 of uiscrollview
  </code></pre>
  
  <p>But I see nothing...</p>
  
  <p>I googled some, and found out maybe it's because of the Auto-Layout enabled?</p>
  
  <p>I'm guessing the auto-layout set my UIScrollView's height and width to 0.</p>
  
  <p>But I need to use Autolayout for other elements.</p>
  
  <p>What am i doing wrong ?</p>
