title: UIPicker does not appear in app
body: <p>I was putting an UIPicker in the app but it does not appear in the app when I run it on my actual device.  This is my until now </p>
  
  <pre><code>- (NSInteger)numberOfComponentsInPickerView:
  (UIPickerView *)pickerView
  {
      return 1;
  }
  - (NSInteger)pickerView:(UIPickerView *)pickerView
  numberOfRowsInComponent:(NSInteger)component
  {
      return [genreNames count];
  }
  - (NSString *)pickerView:(UIPickerView *)pickerView
               titleForRow:(NSInteger)row
              forComponent:(NSInteger)component
  {
      return [genreNames objectAtIndex:row];
  }
  
  
  self.genreNames = [[NSArray alloc] initWithObjects:
                       @"t", @"p", @"s",
                       @"c", @"h", @"h", nil];
  </code></pre>
  
  <p>And in the .h file I am doing the correct declaration. </p>
  
  <p>Do I have some missing code?</p>
  
  <p><strong>Update</strong> 
  Yes I used the simulator, and yes I cannot see the picker at all. I am using story board, to which I added the picker. Sorry for lack of info.</p>
