Set Color of UIActivityIndicatorView of a UIRefreshControl?

Question

Is there a way to set the color of the activity indicator (probably UIActivityIndicatorView) of a UIRefreshControl?

I was able to set the color of the 'rubber' and the indicator:

[_refreshControl setTintColor:[UIColor colorWithRed:0.0f/255.0f green:55.0f/255.0f blue:152.0f/255.0f alpha:1.0]];

But I want to have the 'rubber' blue and the activity indicator white, is this possible?

This is not officially supported, but if you want to risk future iOS changes breaking your code you can try this:

Building off ayoy's answer, I built a subclass of UIRefreshControl, which sets the color of the ActivityIndicator in beginRefresing. This should be a better place to put this, since you may call this in code instead of a user causing the animation to begin.

@implementation WhiteRefreshControl : UIRefreshControl

- (void)beginRefreshing
{
    [super beginRefreshing];

    NSArray *subviews = [[[self subviews] lastObject] subviews];
    //Range check on subviews
    if (subviews.count > 1) 
    {
        id spinner = [subviews objectAtIndex:1];
        //Class check on activity indicator
        if ([spinner isKindOfClass:[UIActivityIndicatorView class]]) 
        {
            UIActivityIndicatorView *spinnerActivity = (UIActivityIndicatorView*)spinner;
            spinnerActivity.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;
        }
    }
}
