Setting corner radius on UIDatePicker with a background color

Question

I have a UIDatePicker in my view and have set the background color of the UIDatePicker:

self.datePicker.backgroundColor = [UIColor lightTextColor];
self.datePicker.layer.cornerRadius = 10;

This successfully puts a background behind the UIDatePicker (which in iOS7 is essentially transparent) but fails to make the rounded corners for the background that I am looking for (I do this same thing for an image on the screen and it works perfectly).
It seems that the corner radius doesn't affect the background color.
Is there a way to fix this problem by setting a corner radius for the background color (or any another solution).

The reason I want to do this is because the ordinary UIDatePicker looks awkward in the view I have constructed and looks much better with a background color.
However, all the other items in the view have rounded corners and I want the UIDatePicker to match them.

Thanks.

You have to add layer.masksToBounds=YES;

Try this,

self.datePicker.backgroundColor = [UIColor lightTextColor];
self.datePicker.layer.cornerRadius = 10;
self.datePicker.layer.masksToBounds=YES;
