Multiple Iboutlets in Same Line of Same Type in Swift

how to create one iboutlet for multiple buttons in swift

you can use IBoutlet Collection !

You can connect several same types of objects after declaring as IBoutlet Collection.

And if you want to run the same code, you can use the for statement.

for item in myButton {
     item.layer.cornerRadius = 3
 }

Can I connect multiple objects with different tags to the same IBOutlet?

Use IBOutletCollection to add an outlet collection to your view controller, like this:

@property (retain, nonatomic) IBOutletCollection(UIButton) NSMutableSet* buttons;

This will let you connect all your buttons to one outlet. The property buttons will be a NSMutableSet containing all your buttons. You can continue to identify individual buttons using the button's tag property. This is handy if you want to iterate through all your buttons, perhaps to set up each button's image:

for (UIButton *b in self.buttons) {
    b.imageView.image = [self imageForTag:b.tag];
}

(You'll need to supply the -imageForTag: method to provide the right image for a given tag, or find some other way to map from tags to images.)

Of course, if you already know the range of tag values for all your buttons, and if you've taken care to make the tags unique inside the view containing all the buttons, you can also just fetch each button individually using -viewWithTag:. This is probably not as fast as having the whole set of buttons already created, as you have with the outlet collection described above, but it does mean that there's one less thing to maintain.

Swift ios connect multiple items to the same IBOutlet

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.

Swift. Changing multiple UIButtons with IBOutlet

Set your button tags in series like 101 to 125 and on click of any button perform this operation

for(UIButton *button in <parent view of buttons>.subviews){
   if(button.tag >= 101 && button.tag <= 125){
      button.setTitleColor(UIColor.redColor(), forState: .Normal()
   }
}

For Swift

for subview in self.createBugView.subviews {

     if let button = subview as? UIButton {
        // this is a button
       if(button.tag >= 101 && button.tag <= 125){      
             button.setTitleColor(UIColor.red, for: .normal)
            }
        }
     }

Why do IBOutlets only respond to one of the multiple view controllers?

Make sure you specified the correct "Custom Class" for each of your view controllers.

That is, set ViewController as the custom class for each of your view controllers.
