I am trying to center and change the size of the text inside my UIPicker but am not sure how... I think it might happen in one of these methods, most likely the first...

```
- (NSString*)pickerView:(UIPickerView*)pv titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
    return [[NSString stringWithFormat:@"%x",row ] uppercaseString]; //Sets picker options as an Uppercase Hex value
}

#pragma mark UIPickerViewDataSource methods

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView*)pv
{
    return 5; //5 columns in the picker
}

- (NSInteger)pickerView:(UIPickerView*)pv numberOfRowsInComponent:(NSInteger)component
{
    return 16;
}

```

Dose anyone one know how this can be done? I have looked around but the documentation is fairly thin...
