Multiple components/columns of different sizes in UIPickerView

I have a UIPicker view with multiple components/columns. Is it possible for the components to be different sizes?

You use the following...

- (CGSize)rowSizeForComponent:(NSInteger)component

Simply return the relevant size for each column (component) via this method. Set your view to be the delegate for the picker and implement the above method.

UPDATE: As pointed out by Dave, I picked the wrong method, I meant to specify the one in the delegate...

– pickerView:widthForComponent:

<UIPickerViewDelegate> has a method you can optionally implement to define a custom width for a component:

- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component

Your UIPickerView delegate object can implement this to return any number you like. This number will be used as the .width of the struct returned from -[UIPickerView rowSizeForComponent:].
