Performing a segue from a button called from NSObject

Question

I have 2 ViewControllers : 1) MainViewController 2) WebViewController

and a segue with identifier ShowWeb.

MainViewController Contain Multiple NSObjects instances initiated from one class Name AppView: NSObject

inside each NSObject there is a UIButton that I want it to perform the segue of type show.

How to perform the segue?

sorry if my question is repeated but i searched yesterday for about 4 hours all the site and didn't find the exact manner, and to know I am using swift.

I Will explain more clearly:

class MainViewController: {

    var appviews = [AppView]()
override func viewDidLoad() {
    super.viewDidLoad()
        for i = 0; i < MyApps.count ; ++i{
            var appview =  AppView()
            appview = AppView(sourceView: AppsScrollView, AppIconURLString: AppPicture,AppName: "MyAppName", LoadedDescription:"Very Good Application", ObjectNo: i, LinkButtonString: "http://stackoverflow.com/posts/28288611")
            appviews.append(appview)
}
}
