NVProgressHUD

A simple progress HUD using NVActivityIndicatorView

Installation

Just drag the NVProgressHUD.swift file into your project, and install NVActivityIndicatorView

Usage

Firstly,import NVActivityIndicatorView

Then,you can use NVProgressHUD as simple as this:

self.navigationController?.view.showHUD(true)
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) { () -> Void in
    // time-consuming task...
    self.navigationController?.view.hideHUD(true)
}

If you need to configure the HUD, you can do this:

 hud = NVProgressHUD(frame: self.navigationController!.view.frame)
 self.navigationController!.view.addSubview(hud)
 
 hud.labelText = "Loading"
 hud.show(true) 
 hud.hide(true, afterDelay: 2.0) // hide the HUD
