title: UIPickerView issue -- selected row disappears
body: <p>I am facing weird problem with the UIPickerView. I have implemented UIPickerView in my project and when i scroll quickly to select value from it, the selected row disappears. Please have a look at the attached image. </p>
  
  <p>Not only single picker all picker in the project have same issue. I added new date picker without binding it with the code and that too have the same issue. Please can anyone let me know what could be the issue.</p>
