![PKHUD - Swift and easy](https://raw.githubusercontent.com/pkluz/PKHUD/master/README_hero.png)



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



## 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,…

- …as well as **animated** ones.

- Builds as an **iOS 8 framework**.

## Installation

**The recommended way is to use CocoaPods.**



### CocoaPods



To install PKHUD for Swift 2 using CocoaPods, include the following in your Podfile



```ruby

pod 'PKHUD', '~> 3.0'

```



To install PKHUD for Swift 3.x using CocoaPods, include the following in your Podfile



```ruby

pod 'PKHUD', '~> 4.0'

```



To install PKHUD for Swift 4.x, include the following in your Podfile



```ruby

pod 'PKHUD', '~> 5.0'

```



### Carthage



[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.



You can install Carthage with [Homebrew](http://brew.sh/) using the following command:



```bash

$ brew update

$ brew install carthage

```



To integrate PKHUD into your Xcode project using Carthage, specify it in your `Cartfile`:



```ogdl

github "pkluz/PKHUD" ~> 4.0

```



Run `carthage update` to build the framework and drag the built `PKHUD.framework` into your Xcode project.



### Swift Package Manager



To install using Swift Package Manager, add this to the `dependencies:` section in your Package.swift file:

```swift

.package(url: "https://github.com/pkluz/PKHUD.git", .upToNextMinor(from: "5.4.0")),

```



## How To



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

```swift

import PKHUD

```



Now, you can proceed to show an arbitrary HUD (and have it automatically disappear a second later) like this:

```swift

HUD.flash(.success, delay: 1.0)

```



_or_ with a completion handler:



```swift

HUD.flash(.success, delay: 1.0) { finished in 

    // Completion Handler

}

```



alternatively, you can use the more verbose and flexible “plumbing” API:



```swift

PKHUD.sharedHUD.contentView = PKHUDSuccessView()

PKHUD.sharedHUD.show()

PKHUD.sharedHUD.hide(afterDelay: 1.0) { success in 

    // Completion Handler

}

```



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.

```swift

HUD.show(.progress)

        

// Now some long running task starts...

DispatchQueue.main.asyncAfter(deadline: .now() + 2) {

    // ...and once it finishes we flash the HUD for a second.

   HUD.flash(.success, delay: 1.0)

}

```



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.



## Communication _(Hat Tip AlamoFire)_



- If you **need help**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/pkhud). (Tag 'pkhud')

- If you'd like to **ask a general question**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/pkhud).

- If you **found a bug**, open an issue.

- If you **have a feature request**, open an issue.

- If you **want to contribute**, submit a pull request.



## Customization



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.
