  <p>I want to open a UIPickerView on the click of this button. 
  I had created this button and now when the user clicks on it I want to open a UIPickerView. I have seen many tutorials on the Internet but all of them are showing with:</p>
  
  <pre><code>textfield.inputview = uipker // i don't want to use extfield
  </code></pre>
  
  <p>But want to implement it without a textfield.
  Is it possible and if possible then tell me how can I do that.</p>
