title: Unable to get pickerView.tag in -pickerView:accessibilityLabelForComponent: method
body: <h3>Protocol:</h3>
  <p><code>UIPickerViewAccessibilityDelegate</code></p>
  <h3>Method:</h3>
  <p><code>-pickerView:accessibilityLabelForComponent:</code></p>
  <h3>Problem:</h3>
  <p>Apple Documentation says</p>
  <pre><code>- (NSString *)pickerView:(UIPickerView *)pickerView
  accessibilityLabelForComponent:(NSInteger)component
  </code></pre>
  <p>But the pickerView which I get inside this method
  is NOT a UIPickerView*,
  but is a UIAccessibilityPickerElement,
  and hence using pickerView.tag inside this method crashes.</p>
  <p>I have 2 pickerviews in my view controller and I need to access the tag to identify them.</p>
  <h3>Question:</h3>
  <p>How can I provide accessibilityLabel for components of both pickerViews in this method?</p>
