Contents of the cell superimposed in iOS7

[KarianSilva]

Hi! I'm trying to use your component, but i had compatibility issues with iOS7. In iOS6 everything is working perfectly. But when I use iOS7 the content of cells is superimposed on each scroll. In my view there must be something wrong with the 'objectAtIndexPath' method because overlapping content is an equivalent line of my source ArrayList.

Below the pictures iOS6 (correct) and iOS7 (bug)

Hi @KarianSilva , is there any chance you can send me a little example project to try to reproduce the problem? Or maybe you can paste the code from your UITableView datasource on this ticket?

Hi @KarianSilva - here's your problem:

    UILabel *labelMedicamento = [[UILabel alloc]initWithFrame:CGRectMake(32, 10, 268, 21)];

    UILabel *labelSubstancia = [[UILabel alloc]initWithFrame:CGRectMake(32, 36, 255, 12)];

. . . 

    [cell.contentView addSubview:labelLaboratorio];

Because you're creating these labels and adding them to your tableview cell in your datasource, you're adding more and more labels to your cells each time a cell is reused.

You should instead create your own subclass of UITableViewCell, with each of your custom labels as @properties.

Apple has a great guide for this.

Thanks for using CGLAlphabetizer, and let me know if you run into any other issues!

[KarianSilva]

Really?

Good, as it worked perfectly in the iOS6, I had thinking that the code was correct.

I'll make those changes you said and come back here to tell if it worked!!

Many thanks for providing and sharing this with us.

=)
