A Swift based reimplementation of the Apple HUD (Volume, Ringer, Rotation,…) for iOS 8.

Features

• Official iOS 8 blur effect via UIVisualEffectsView.
• Proper rotation support.
• Size / Device agnostic.
• Works on top of presented view controllers, alerts,…
• Comes with several free resources - Checkmark, Cross, Progress Indicator,…
• Builds as an iOS 8 framework.

How To

After adding the framework to your project, you need to import the module

1

import PKHUD

As of the initial release, there is six out-of-the-box types of content views you can present.

• HUDContentView.TextView(...) provides a wide, three line text view, which you can use to display information.

• HUDContentView.ImageView(...) - provides a square view, which you can use to display a single image within.

• HUDContentView.ProgressView(...) - provides a square (indeterminate) progress view.

• HUDContentView.TitleView(...) - provides a square view, which you can use to display a picture and a title (above the image).

• HUDContentView.SubtitleView(...) - provides a square view, which you can use to display a picture and a subtitle (beneath the image).

• HUDContentView.StatusView(...) - provides a square view, which you can use to display a picture, a title and a subtitle. This type of view replicates the Apple HUD one to one.

You can present the HUD with a content view by using the controller.

var contentView = HUDContentView.ProgressView()
HUDController.sharedController.contentView = contentView
HUDController.sharedController.show()

You can dismiss it in a similar manner.

1

HUDController.sharedController.hide(animated: true)

…or with a delay.

HUDController.sharedController.hide(afterDelay: 2.0)

Customization

There are two properties at your disposal to customize general behavior.

• HUDController.sharedController.dimsBackground: Bool defines whether the background is slightly dimmed when the HUD is shown.

• HUDController.sharedController.userInteractionOnUnderlyingViewsEnabled: Bool defines whether the underlying views respond to touches while the HUD is shown.

Additionally you are free to create you own custom content views. They can either descend from HUDContentView.SquareBaseView, HUDContentView.WideBaseView or simply UIView.

Note: It’s neither possible to customize the general look and feel, nor do I plan to add that feature. You are free to provide any content views you wish but the blurring, corner radius and shading will remain the same.

Disclaimer

While basically feature complete and stable, make sure you understand that the API will change as Swift matures and some of the annoying compiler quirks are resolved.
