title: UIWebview won't zoom even after setting scalesPageToFit to YES
body: <p>I have a <code>UIWebview</code> that is loaded as a subview when a user selects a tab on a <code>UISegmentedControl</code>. For some reason, I can not get it to allow <code>pinch/zooming</code>.
  I set the following code in the <code>viewDidLoad:</code> method, so it should work.</p>
  
  <pre><code>self.myWebView = [[[UIWebView alloc] initWithFrame:self.view.frame] autorelease];
  self.myWebView.backgroundColor = [UIColor whiteColor];
  self.myWebView.scalesPageToFit = YES;
  self.myWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
  self.myWebView.delegate = self;
  [self.view addSubview: myWebView];
  </code></pre>
  
  <p>I tried loading a <code>UIWebView</code> from a NIB and creating it programmatically with no avail. Is there something I'm missing? What could be causing the webview to ignore pinching and zooming?</p>
  
  <p>Thanks!</p>
