A Swift based reimplementation of the Apple HUD (Volume, Ringer, Rotation,…) for iOS 8.
- 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,…
- …as well as animated ones.
- Builds as an iOS 8 framework.
First you need to add the framework to your project. The recommended way is to use CocoaPods.
pod "PKHUD"
After adding the framework to your project, you need to import the module
import PKHUD
Now, you can proceed to show an arbitrary HUD (and hide it soon after) like this:
PKHUD.sharedHUD.contentView = PKHUDSuccessView()
PKHUD.sharedHUD.show()
PKHUD.sharedHUD.hide(afterDelay: 2.0);
You can also hot-swap content views - this can prove useful if you want to display a progress HUD first and transform it into a success or error HUD after an asynchronous operation has finished.
PKHUD.sharedHUD.contentView = PKHUDProgressView()
PKHUD.sharedHUD.show()
let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(2.0 * Double(NSEC_PER_SEC)))
dispatch_after(delayTime, dispatch_get_main_queue()) {
PKHUD.sharedHUD.contentView = PKHUDSuccessView()
PKHUD.sharedHUD.hide(afterDelay: 2.0)
}
Please note that there are multiple types of content views that ship with PKHUD. You can find them as separate files in the project folder as well as in the ContentViews
group in Xcode.
There are two properties at your disposal to customize general behavior.
-
PKHUD.sharedHUD.dimsBackground: Bool
defines whether the background is slightly dimmed when the HUD is shown. -
PKHUD.sharedHUD.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 descend from any UIView
type or the predefined base classes PKHUDSquareBaseView
and PKHUDWideBaseView
.
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.
