Changing style of pickerview.

Question

How can I change the style of pickerview. I want to change its white background to green color and its black frame to red color. Anyone please help. I am a beginner.

As far as I know you can't actually change the frame's color, but you can create an image with a transparent area in the middle and add that on top of the frame like so:

[picker addSubview:image];

As for the background color, you can create your own custom views for each row by implementing the UIPickerViewDelegate method:

- (UIView *)pickerView:(UIPickerView *)pickerView 
                        viewForRow:(NSInteger)row 
                        forComponent:(NSInteger)component
                        reusingView:(UIView *)aView;

You could then set the background color of the view you return via

[myView setBackgroundColor:[UIColor yellowColor]];

However this only affects the rows with data. I don't think you can currently set the background color of the component itself which is a shame.
