Multiplying interface elements?

🎤 General Discussion Swift
1

Hello there,

First post, first question… Currently developing my first “big app”, I’m looking for the (best) way to duplicate elements and their usage.

Here’s the two situations where I need it to happen…

  1. Multiple players

My app asks for name, a number, a color for X players. Depending on X I have to duplicate rows and then get access to the variables like “name_1”, “name_2”, and so on.
For now, I’m managing two players by duplicating fields in the storyboard and hiding the one I don’t need. It works but it’s not clean and will become a problem with 5 players…

How do I create / duplicate lines programmatically and maintain access to the data ?

  1. Multiple scores
    After the game is created, I will ask the user to enter data on several categories for each player.

I have a column with 7 different textfields for each players where the user will enter corresponding values.
Same question as above but maybe same answer ?

Thanks a lot for any help !

Ben

Check out UICollectionView or UITableView.

You can define a custom cell with all of your interface elements for a single player, and then set your collection/table size to the desired number of players. Store all your player info in an array and use that array to feed the cells in your collection/table.

We’ve got a bunch of tutorials on this site that can help you get started. Here is one for UICollectionView.

Have fun!

Thanks for The reply, I begin ton undrestand the idea.

But is it possible for the players’ scores, that the UICollection cells contain a single column table view ?

Most important how do I link actions to the inner elements (fields, buttons, etc) that are specific to each player (ie altering his score) ?

Thx
