I wonder if its OK to connect multiple items to the same IBOutlet? In my tableView I have setup two cells and given them a uniqe identifier.

But I have connected the label in each cell to the same IBOutlet in my custom UITableViewCell class.

enter image description here

class SearchSubCatTableViewCell: UITableViewCell {

  
    @IBOutlet weak var subCatTitle: UILabel!

So I have two labels connected to @IBOutlet weak var subCatTitle: UILabel!

This all works fine when I am testing the app but can it cause any problems?

Yes, this is ok as long as you don't plan on doing any operations on those labels.

The correct way to do it, is by creating an array IBOutlet:

@IBOutlet var collectionOfLabels:[UILabel]?

  • Connect all your labels to this labels array outlet.

  • Then access the labels via the array.

  • What do you mean by operations? The only thing I do now is to set a title – user2636197 Aug 11 '16 at 15:36
  • If you set the title once at the interface builder then fine, but if you need to change it later programmatically then that would cause a problem. @user2636197 – Roy K Aug 11 '16 at 15:37
  • Would the app crash? Right now one cell has a static label and the second cell has a dynamic label from JSON data – user2636197 Aug 11 '16 at 16:23
  • Good chances that it will crash at some point, I would suggest not to take the risk and write it in a proper way. – Roy K Aug 11 '16 at 16:24
  • Is it okay if I loop through these objects, and than do something with it. Like changing the alpha? – Stijn Westerhof Jan 31 '17 at 11:53

This may cause a problem when you will try to perform some operations on the label text data.I would suggest you to have a look at IBOutlet Collections.You can find nice tutorial here.

You can connect multiple view/labels/etc to one @IBOutlet while they are from different parents.

Egzample: You have one class HeaderView with label and imageView, but you have 3 separated xib files which contains HeaderView (lets say for 3 kinds of devices (iPhone, iPhone 6Plus, and iPads). You set class of this views as HeaderView and connecting @IOBoutlets to one link.

If you want create @IBOutlet collection you have to define your outlet as array of type. For example: @IBOutlet private var labels: [UILabel]!

No, it won't cause any problems.

I used a similar setup in my app and it got accepted into the app store.

you will not face a problem if you connect multiple buttons with the same Outlet. You might face some issues if you try to perform functions on these buttons. I would suggest you to have a look at using tags if you wish to perform functions on these buttons.
