Update SWCellButtonItem's image on tap

[andreamazz]

Hi First of all thanks for this library, it works just great. I was wondering if there's a way to change the SWCellButtonItem's image within the handler of the item. Something along this lines:

    SWCellButtonItem *item = [SWCellButtonItem itemWithImage:[UIImage imageNamed:@"on"] handler:^(SWCellButtonItem *item, SWRevealTableViewCell *cell) {
        item.image = [UIImage imageNamed:@"off"];
    }];

I need to do this since my image is a toggle associated with the cell. Is there any way to do so? Thanks

I am not sure if I understand your requirement. The handler is called when you tap on the button item, but at this time you should dismiss the revealing cell, so I am not sure if you want to replace the image at this time. Can you be more specific about what visual behavior you would want? Thanks

I'm using the right buttons as flags to vote an item up or down. I don't want to dismiss the cell (so that the user can change his vote without swiping the cell away a second time), but provide a visual feedback of the user's action (by switching the outlined up/down icon with a 'full' icon).

This might help understanding what I mean: http://d.pr/i/yPfh (I currently implemented this with SWTableViewCell, but it breaks down with iOS8)

Oh I see. I suppose this can be done by allowing setting item properties after they have been provided by the datasource. Currently, changing item properties only have an effect for the next revealing. I think UIBarITems update on screen by simply setting their image property, so I guess we could take a similar approach. Would that work?

Yep, that would be great! thanks

:+1: for this enhancement - I am also keen to use this when it is available.
