How to change UIButton to a different Uibutton after clicking segmented controller?-CodePudding

The image below is a picture of a view with two uibarbuttons and a segmented control. The salesforce button when reached redirects the user to a website.How can I change the salesforce button to a different button when the third index of the segment control is reached ? This second button is meant to display a new view controller.

I think it would be easier to change the appearance and the button behaviour instead of changing the button itself.

Sadly you didn´t provide any context if this view is from a storyboard or created by code. In my answer I´m assuming it´s from storyboard.

Create an outlet for you button:
```
@IBOutlet weak var myButton: UIButton!
```
From your UISegmentedControl in storyboard create an IBAction in your viewcontroller. That action should look something like this.
```
@IBAction func segmentedControl(sender: AnyObject) {

    configureButton(for: segmentedControl.selectedSegmentIndex)

}
```

Then create that function:

 func configureButton(for index: Int){
      switch index{
          case 1:
            // assign the function that should execute as soon as the button gets pressed
            myButton.addTarget(self, action: #selector(functionName), for: .touchUpInside)
            // change title
            myButton.setTitle("title for button", for: .normal)
          // add all other cases
          // add default
          default:
            print("not implemented")
      }


  }

If no IBAction is defined for your myButton you would need to call the configureButton function from your viewDidLoad function.

Firstly get the index of the selected segment using, .selectedSegemtIndex property.Then, check the condition stating that, if the index is equals your target segment index, define statements to change the title, background color, or even the action of the button if required.
