Hello,
I'm googling for hours and didn't any solution to my problem. I hope someone will be able to help me there

For my current app, I need to customize a picker in order to have a kind of horizontal scroller which will be used to selected an int within a big range ( 0 to 5000).
I already managed to rotate my Picker, and to fill it with images, and it looks pretty cool :

Thus, as you can see on my screenshot that I have a problem : the Picker displays at its beginning and its end some white empty lines.
Is there a way to change the picker's Background color ?
I tried several things, like :
Code:
- (UIImageView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
view.backgroundColor = [UIColor redColor];
or
Code:
myPicker.backgroundColor = [UIColor redColor];
But it's not working.
Then, I tried to use some white images, and to put a transparent red image over my Picker, but the result isn't good :s
Have you got any other idea to change a pickers background color ?
The second part of my problem is that the picker runs very slow, and when you need to scroll from the 1st to the 5000st element, it takes too much time.
Is there a way to change the pickers speed ?
Thank you very much for your answers !
