Change UIDatePicker font color?

All I need (on iOS 8.x and 9.0) is this one line to change the font color:

        [my_date_picker setValue:[UIColor whiteColor] forKey:@"textColor"];

No subclassing or invoking of private APIs…

Note: today’s current date will still be highlighted (in newer iOS versions). You can get around this by using the following code:

if ([my_date_picker respondsToSelector:sel_registerName("setHighlightsToday:")]) {

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wundeclared-selector"

        [my_date_picker performSelector:@selector(setHighlightsToday:) withObject:[NSNumber numberWithBool:NO]];

#pragma clang diagnostic pop

}
