How to tint peek&pop custom actions?

Question

When pick&pop view is presented, custom actions (UIPreviewAction objects) are shown in default iOS blue color. Is there any way they can be tinted in different color?

For iOS 11, what seems to work is adding in didFinishLaunchingWithOptions:

UIApplication.sharedApplication.delegate.window.tintColor = MY_COLOR

I'm not sure if the same approach would work for pre-iOS11 versions, but here is what worked for me for pre-iOS11:

in viewWillAppear method of a preview controller (viewController which implements previewActionItems method add:

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    UIView* container = [self.view superviewOfClass:NSClassFromString(@"_UIVisualEffectContentView")];
    container.tintColor = YOUR_COLOR;
}

The superviewOfClass method is implemented in UIView+MyUtils category:

- (UIView*) superviewOfClass:(Class)c
{
    UIView* parent = self;
    while ((parent = parent.superview))
    {
        if ([parent isKindOfClass:c])
        {
            return parent;
        }
    }
    return nil;
}
