SwiftOverlays is a Swift GUI library for displaying various popups and notifications.

SwiftOverlays provides several ways to notify user:

• Wait overlay: a simple overlay with activity indicator

• Wait overlay with text

• Overlay with text only
• Overlay with image and text (can be used with PPSwiftGifs to show custom animated GIF instead of UIActivityIndicatorView)
• All of the above with blocking any user interaction
• Notification on top of the status bar, similar to native iOS local/push notifications

Just clone and add SwiftOverlays.swift to your project.

• Make sure that your Cocoapods version is >= 0.36: pod --version
• If not, update it: sudo gem install cocoapods
• pod init in you project root dir
• nano Podfile, add:

pod 'SwiftOverlays', '~> 0.14'
use_frameworks! 

• Save it: ctrl-x, y, enter
• pod update
• Open generated .xcworkspace
• Don't forget to import SwiftOverlays: import SwiftOverlays!

• iOS 7.0+ (8.0+ if you use Cocoapods)
• Xcode 6.3
• Swift 1.2 (if you need Swift 1.1, use swift-1.1 branch)
• For Swift 2.0 use swift-2.0 branch

If you're using CocoaPods, import the library with import SwiftOverlays

You can use UIViewController convenience methods provided by library:

// In your view controller:
// Wait overlay
self.showWaitOverlay()
// Wait overlay with text
let text = "Please wait..."
self.showWaitOverlayWithText(text)
// Overlay with text only
let text = "This is a text-only overlay...\n...spanning several lines"
self.showTextOverlay(text)
// Remove everything
self.removeAllOverlays()
// Notification on top of the status bar
UIViewController.showNotificationOnTopOfStatusBar(annoyingNotificationView!, duration: 5)
// Block user interaction
SwiftOverlays.showBlockingWaitOverlayWithText("This is blocking overlay!")
// Don't forget to unblock!
SwiftOverlays.removeAllBlockingOverlays()

You can't use SwiftOverlays convenience methods directly with UITableViewController - because its view is, well, an UITableView, and overlay will be scrolled along with it.

Instead I suggest using UIViewController instead of UITableViewController and adding UITableView as a subview.

If for some reason you can't use UIViewController, you can do something like:

SwiftOverlays.showCenteredWaitOverlayWithText(self.view.superview!, text: "Please wait...")
SwiftOverlays.removeAllOverlaysFromView(self.view.superview!)

(but in that case overlay will be added to the superview, and you should obviously do that only if superview is available - for example in viewDidAppear method of your controller.).
