This is a very useful technique and it’s pretty straight forward. Let’s say we have an array of items or heroes and we want to dynamically create buttons that will do something linked to the hero/item selected. One example is if you have an array of saved games and you want to generate buttons to […]

Contacts App / Inventory with Archiving 2.0

Hi, all Here is the updated version of the Contacts app with archiving. It will now let you save and load multiple contacts. I am just going to list some of the new things added. Here are the previous and next buttons on the Load View screen:

@IBAction func previousPressed(sender: AnyObject) { // PREVIOUS BUTTON
        
        if index == 0 {
            index = inventory.itemArray.count - 1
            
        } else {
        index--
        }
        println("index: (index)")
        indexLabel.text = "(index + 1)"
        loadItem(inventory.itemArray[index])
        changePlaceHolderText()
        
    }

        }
        println("index: (index)")
        indexLabel.text = "(index + 1)"
        loadItem(inventory.itemArray[index])

It’s a very simple app, but to me it was a very good experience learning to build and troubleshoot things directly in code. The app will look […]
