Use of MBProgressHUD Globally + make it singleton

Question

In my Project, each of the user interaction events make a network call (Which is TCP, not HTTP). I need Activity Indicator to be global to show from a rando

Answer 1

I found @Matej Bukovinski 's answer very helpful, since I just started using Swift and my purpose using his methods was to set a global font for the MBProgressHUD, I have converted the code to swift and am willing to share the code below:

class func showGlobalProgressHUDWithTitle(title: String) -> MBProgressHUD{
    let window:UIWindow = UIApplication.sharedApplication().windows.last as! UIWindow
    let hud = MBProgressHUD.showHUDAddedTo(window, animated: true)
    hud.labelText = title
    hud.labelFont = UIFont(name: FONT_NAME, size: 15.0)
    return hud
}

class func dismissGlobalHUD() -> Void{
    let window:UIWindow = UIApplication.sharedApplication().windows.last as! UIWindow
    MBProgressHUD.hideAllHUDsForView(window, animated: true)
}

The above code is put into a global file where I keep all my global helpers and constants.
