Swift put multiple IBOutlets in an Array

Question

I made these (marked with red border) IBOutlets using ctrl + drag

But i don't like to have the exact same line 9 times (DRY)

How do i put these IBOutlets in an Array?

Answer 1

you can define a generic outlet collection in Swift like this:

@IBOutlet var collectionOfViews: Array<UIView>? // = [UIView]? 

or for e.g. UIButton objects:

@IBOutlet var collectionOfButtons: Array<UIButton>? // = [UIButton]? 

---

you can find your collections under the Outlet Collections group as usually are in the File's Owner:

it would look on my console after connecting 5 random buttons:

Answer 2

Follow these steps to create an array of outlets an connect it with IB Elements:

• Create an array of IBOutlets
• Add multiple UIElements (Views) in your Storyboard ViewController interface
• Select ViewController (In storyboard) and open connection inspector
• There is option 'Outlet Collections' in connection inspector (You will see an array of outlets there)
• Connect if with your interface elements

class ViewController2: UIViewController {       @IBOutlet var collection:[UIView]!       override func viewDidLoad() {         super.viewDidLoad()     } }
