Using it in UITableViewCell

[danglade]

Hello,

Love your project. Can I use this category in a UITableViewCell?

[mamaral]

Yes, you can use it in any UIView, just put your layout code in layoutSubviews.

[danglade]

Thank you! Will try it!

[mamaral]

No problem, LMK if you have issues!

[danglade]

Maybe I'm doing something wrong when reusing the cells, but I don't think so. Look at the behavior of the cells.

Look at this video -> https://www.dropbox.com/s/uc9jqdpmvofom4v/Untitled.mov?dl=0

Let me know,

Thanks

    }

        cell.userInteractionEnabled = YES;
        _label = [UILabel new];
        [_label sizeToFit];
        _label.font = [UIFont systemFontOfSize:24];
        _label.text = @"Pruebaaa";
        [cell addSubview:_label];

        // Configure the cell...
        cell.selectionStyle = UITableViewCellSelectionStyleBlue;
        cell.backgroundColor = [UIColor colorWithRed:0.957 green:0.957 blue:0.957 alpha:1] /*#f4f4f4*/;


                return cell;
}

I'm reading this on a phone at the moment so not 100% sure, but it looks like your adding 1 instance of a label as a subview to multiple cells.

[danglade]

Correct, and it won't show that label until I scroll the view. Which is weird.

If I do cell.textlabel.text it will show at the beginning with no scrolling needed.

[mamaral]

Yeah the problem has nothing to do with Facade or the layout, it has to do with cell reuse. You cant have the same view as a subview of multiple views. Each cell needs its own instance of that label.

[danglade]

I understand, what would be the best practice here to use Facade on a UITableViewCell?

[mamaral]

Subclass UITableViewCell, put a label in there, and in that cell's layoutSubviews method is where you would have your Facade code.

In one of my open source apps, I have a UICollectionViewCell I do this with. You can reference the source here:

I will check it out!

Thank you man!
