Hi Support team,

I want to change background color (make a grey transparent color) of thumbnail slider. I can't find an object reference in kit which I can use to change the color.

I can see an other discussion here "; but in latest FPK sdk, "DocumentViewController"'s implementation is not open to developer.

Please suggest. Looking forward to a response quickly.

    The controller's toolbarBackgroundImage is used as a background image for the thumbnail and page slider container, which is actually a UIToolbar.

    Default image is a black image with 0.5 alpha or something like that.

    I tried to find the image, but did not find it.

    DocumentViewController is part of fpk core libraries. I am not finding any object from which I can change background color.

    I found "pagedScrollView" which is read only. I tried to use "thumbnailBackgroundColor" property to change color but that is also not helping.

    Please suggest.

    It is a MFDocumentViewController's property.

    @property (strong, nonatomic) UIImage * toolbarBackgroundImage;

    Hi Matteo,

    I used this property, tried to change image before loading toolbar. Also tried to use after loading toolbar but its not making any difference.

    Please suggest.

    This is what I got with the following snippet of code

     docViewController.toolbarBackgroundImage = [UIImage imageNamed:@"testToolbarBackground"];
    [self presentViewController:documentViewController animated:true];

    where testToolbarBackground is more or less a red png with 0.25 alfa.

    If you are experiencing different results, I can think of a few issues right now:
    - you are running a different version than us. Use the usual NSLog(@"%@", [MFDocumentManager version]) to retrieve it. - the image is somehow wrong. Maybe files with the same name among the resources? - you have some other customization going on that's overriding the toolbarBackgroundImage property. Maybe you are also setting the thumbnailScrollView background to something else, for example?
