title: How to create a UIPickerView over UITabbar Controller?
body: <p>In my app I have a <code>UITabBarController</code>.In one <code>UIViewController</code> I want to have a <code>UIPickerView</code>.I added this pickerview in the .<code>xib</code> file itself by adding it in separate view and keeping it out of frame until user taps the button.when the user taps the button,I unhidden this view and set a animation like keyboard.But my problem is, when the <code>UIPickerView</code> comes,it is coming under the <code>UITabBarController</code> ie.,tabbar controller is hiding half of the <code>UIPickerView</code>.I want to keep my <code>UIPickerView</code> over that <code>UITabBarController</code>.How can I do this.Please help.</p>
  
  <p>Thanks u.</p>
