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?

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:

Swift put multiple IBOutlets in an Array, you can define a generic outlet collection in Swift like this: @IBOutlet var collectionOfViews: Array<UIView>? or for e.g. UIButton objects: Swift a placé plusieurs IBOutlets dans un tableau j'ai fait ces (marqué avec la bordure rouge) IBOutlets en utilisant ctrl + drag mais je n'aime pas avoir exactement la même ligne 9 fois (sèche)

Swift put multiple IBOutlets in an Array, 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​  updated swift code of Rebeloper: let BedroomFloorKey = "BedroomFloor" let BedroomWallKey = "BedroomWall" var bedroomFloorID: AnyObject = 101 var bedroomWallID: AnyObject = 101 func saveGameData() { let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) as NSArray let documentsDirectory = paths.objectAtIndex(0) as!

Solution here Swift - IBOutletCollection equivalent

@IBOutlet var objectCollection: [Object]

What is an IBOutletCollection in iOS?? - Abhimuralidharan, As the name says, an IBOutletCollection is a collection of IBOutlets. It can either There are two rather curious things to note about an IBOutletCollection array: Its order is Set tag to all the buttons in the correct order . ie; from 1 to 5. Connect  Swift makes it easy to create arrays in your code using an array literal: simply surround a comma-separated list of values with square brackets. Without any other information, Swift creates an array that includes the specified values, automatically inferring the array’s Element type.

Start with the two view pane where you see both your code and the storyboard. When you make your first IBOutlet connection from the UI to your code, just look carefully at the Connection drop down field and select the option called "Outlet Collection". This will automatically create an array of IBOutlets. Next just look for the little black circle within a circle that is placed in your code where the array is created. Just drag from this circle to all the other UI objects you want to connect to that same collection (not sure if you can mix types). Similarly you can connect all the objects to one Action by dragging from the first black dot created to all the other objects you want to wire up to that action. Also consider EnumerateSequence() to help in working with this Collection. Sweet right?

Swift put multiple IBOutlets in an Array - St4k, you can define a generic outlet collection in Swift like this: @IBOutlet var collectionOfViews: Array<UIView>? // = [UIView]?. or for e.g. UIButton  Swift 4 arrays are used to store ordered lists of values of the same type. Swift 4 puts strict checking which does not allow you to enter a wrong type in an array, even by mistake. If you assign a created array to a variable, then it is always mutable, which means you can change it by adding, removing,

IBOutletCollection - St4k, Assigning Buttons Inside An Outlet Collection Different Values (Swift 3 Xcode 8) arraysswiftuibuttoniboutletcollection Swift put multiple IBOutlets in an Array. Swift’s Array types are implemented as structures. This means that arrays are copied when they are assigned to a new constant or variable, or when they are passed to a function or method. var numbers = [ 1 , 2 , 3 ] var otherNumbers = numbers // this will create a copy of numbers // this will append 4 to otherNumbers but not to numbers otherNumbers . append( 4 ) // numbers = [1, 2, 3] // otherNumbers = [1, 2, 3, 4]

Creating the interface with UIStackView, These seven buttons will be used to store the columns in our game, so to make There are two more things to do in Interface Builder before we can get on with These are just IBOutlet arrays that work like normal Swift arrays, except in IB you​  We use something called Array in Swift. What is an array? An array is simply a container that can hold multiple data (values) of a data type in an ordered list, i.e. you get the elements in the same order as you defined the items in the array. An array can store values of any data type e.g. Int, String, class etc.

Interface Builder Outlet Collections, you can define a generic outlet collection in Swift like this: @IBOutlet var collectionOfViews: Array<UIView>? // = [UIView]?. or for e.g. UIButton objects: @​IBOutlet  Declaring Array in Swift. Compared to Objective-C, Swift arrays are not as picky. Swift accepts any type, not just classes in an array. Declaring static and dynamic arrays is the difference between let and var. The let declaration gives us a static array and the var a dynamic array. In both cases we set the initial values of the array in the

  • How do i connect the buttons from the storybord to this array?
  • @CorPruijs, you can find your collection under the Outlet Collections group. you can connect the multiple items to the collection as usually you'd do in the case of one outlet.
  • I keep getting a "not initialized at super.init call" error, i have tried "@IBOutlet var levelField: Array<UIButton> = Array<UIButton>" and "@IBOutlet var levelField: Array<UIButton> = UIButton" and using a for loop but nothing worked
  • @CorPruijs, is that your code, @IBOutlet var levelField: Array<UIButton> = Array<UIButton>...? you don't need the right size of the operand, please chuck everything away after the = symbol including the = too; please see my answer, I have not assigned anything to it, because it is needless.
  • That's the first thing i tried off course, but it didn't work. <br> Then i tried using the = Array<UIButton> thingy because i needed "= UIButton()" when i did a single button
  • This was great. Help me a bunch.. Thanks
  • Thank you!, save my time
  • The animation was a life saver. Thanks!
  • This answer is way too brief, provides no details, and should be removed.
  • or, perhaps the writer can expand on their answer
  • The answer only needs to be brief
