title: Show UIPickerView when editing UITextField
body: <p>I want to show a UIPickerView and not the keyboard when I edit a UITextField. I tried this: </p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      depCityField.inputView=pickerDestinations;
      comeCityField.inputView=pickerDestinations;
  }
  </code></pre>
  
  <p>It doesn't work, but with UIDatePicker it works fine...</p>
