title: How to set a default Value of a UIPickerView
body: <p>I have a problem with my UIPickerView.
  I have 3 values in it EU AP and NA.
  When I start the app EU seems to be selected but when I make a <code>NSLog(@"%@", [regions objectAtIndex:row]);</code> I only get back <code>(null)</code>,
  now when I touch the UIPickerView the EU value is selected and I get <code>"EU"</code> back from a NSLog.</p>
  
  <p><strong>My question is:</strong> </p>
  
  <p>How can I define a default value which is selected (not only the label) when the user only starts the app and touches nothing.</p>
  
  <p><em>Edit:</em> Here is my code to get the selected item:</p>
  
  <pre><code>#pragma mark -
  #pragma mark PickerView DataSource
  
  - (NSInteger)numberOfComponentsInPickerView:
  (UIPickerView *)pickerView
  {
      return 1;
  }
  - (NSInteger)pickerView:(UIPickerView *)pickerView
  numberOfRowsInComponent:(NSInteger)component
  {
      return [regions count];
  }
  - (NSString *)pickerView:(UIPickerView *)pickerView
               titleForRow:(NSInteger)row
              forComponent:(NSInteger)component
  {
      return [regions objectAtIndex:row];
  }
  
  #pragma mark -
  #pragma mark PickerView Delegate
  -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row
        inComponent:(NSInteger)component
  {
  
                  selectedRegion = [[NSString alloc] initWithFormat:
                                @"%@", [regions objectAtIndex:row]];
      NSLog(@"%@", selectedRegion);
  
  
  }
  </code></pre>
