Have a look at this: How to open fb and instagram app by tapping on button in Swift

1st links on Google. Or are you looking for something different ?

EDIT: You asked me how to make the button trigger an event, here' how:

1) Open the Assistant editor by using ALT-CMD-ENTER.

2) Create an IBAction from your button by CTRL dragging from the button to your code:

enter image description here

3) Put the necessary code in your IBAction, for example:

@IBAction func Fb(sender: UIButton) {

        if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
            let fbShare:SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)

            self.presentViewController(fbShare, animated: true, completion: nil)

        } else {
            let alert = UIAlertController(title: "Accounts", message: "Please login to a Facebook account to share.", preferredStyle: UIAlertControllerStyle.Alert)

            alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
            self.presentViewController(alert, animated: true, completion: nil)
