attach several UILabels from storyboard to one IBOutlet-CodePudding

I've 15 Labels in my Storyboard they are just texts, also set from storyboard, What I want to do is to style them, but programitically, Therefore I need to create 15 IBOutlets in my ViewController, I wonder if there is any other way of doing that, without 15 IBOutlets,if it's possible to create 1 IBOutlet and attach all of them to that one? because creating 15 of them is kinda stressing...

CodePudding user response：

You can do this with Outlet Collections instead of an IBOutlet for all the labels you want to group together:

One way to do it is to ctrl drag from your storyboard to your editor and select outlet collection

This will create @IBOutlet weak var labelCollection: UILabel! in your code

This works fine but then you need to add an additional check for the type when looping:

@IBOutlet weak var labelCollection: UILabel!

func setCustomLayout()
{
    for label in labelCollection2.subviews
    {
        if let label = label as? UILabel
        {
            // do your custom set up here
        }
    }
}

What I like to do is to create the specific outlet collection in code first if I way to track the same type like so:

@IBOutlet var labelCollection: [UILabel]!

The I drag from the editor to the storyboard

Then I can work with it as follows

@IBOutlet var labelCollection: [UILabel]!

func setCustomLayout()
{
    for label in labelCollection
    {
        // do your customization here
    }
}

Then you can loop through the UIViews inside the IBOutletCollection and do the needful
