Toggle Tag Method

[AlexHedley]

What would be the best way to have a toggle function so you can change the colour of the tag when you select, deselect it?

#define selectedColor [UIColor colorWithRed: 255.0/255.0 green: 128.0/255.0 blue: 0 alpha: 1.0]
#define deselectedColor [UIColor colorWithRed: 255.0/255.0 green: 0 blue: 0 alpha: 1.0]

From your demo in the viewDidLoad I've amended the block

[self.tagListView addTagsAccordingToDataSourceArray:@[@"from", @"array", @"too"] withOnTapForEach:^(TagView *tagView) {
        if ([tagView.backgroundColor isEqual:selectedColor]) {
            tagView.backgroundColor = deselectedColor;
        } else {
            tagView.backgroundColor = selectedColor;
        }
}

The background colour is set in IB but when compared it doesn't match.

If I add to viewDidLoad

self.tagListView.tagBackgroundColor = selectedColor;

it works.

Your implementation looks OK to me. Please, fill a pull request, and I will be pleased to accept it :)

The only issue here is if you've selected a colour in IB you then have to set it again in code (selectedColor) which would be confusing and not intuitive.

OK, I get your point now. You are saying that IB background color overrides the one setted individually on a tag.

For not letting the IB set the color, you can simply comment the tagBackgroundColor property (this line), and the appropiate getters/setters.

Let me know if you have any trouble with this

I've just updated the library to make working with your issue more easily. Now, you can set the selected / highlighted state and color individually.
