CocoaPods

If you're using CocoaPods, add this to your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
# Or use CND source
# source 'https://cdn.cocoapods.org/'
platform :ios, '12.0'
use_frameworks!

target 'MyApp' do
  # Use the FlyHUD, FlyIndicatorHUD and FlyProgressHUD components.
  pod 'FlyHUD', '~> 1.5.12'

  # Or, just use the FlyHUD component.
  pod 'FlyHUD', '~> 1.5.12', :subspecs => ['FlyHUD']

  # Or, just use the FlyHUD and FlyIndicatorHUD components.
  pod 'FlyHUD', '~> 1.5.12', :subspecs => ['FlyIndicatorHUD']

  # Or, just use the FlyHUD and FlyProgressHUD components.
  pod 'FlyHUD', '~> 1.5.12', :subspecs => ['FlyProgressHUD']
end

And run pod install.

Important

CocoaPods 1.13.0 or newer is required.

Carthage

If you're using Carthage, add this to your Cartfile:

github "liam-i/FlyHUD" ~> 1.5.12

And run carthage update --platform iOS --use-xcframeworks.

Usage

Using HUD in your application is very simple.

• Displays the status HUD of an indeterminate tasks:

let hud = HUD.show(to: view)
DispatchQueue.global().async {
    // Do something...
    DispatchQueue.main.async {
        hud.hide()
    }
}

• Displays a task's progress HUD:

let hud = HUD.show(to: view, mode: .progress(), label: "Loading")
Task.request { progress in
    hud.progress = progress
} completion: {
    hud.hide()
}

• Displays a text-only status HUD:

HUD.showStatus(to: view, label: "Wrong password")

• Displays a custom view's status HUD. e.g. a UIImageView:

HUD.showStatus(to: view, mode: .custom(UIImageView(image: UIImage(named: "Checkmark")?.withRenderingMode(.alwaysTemplate))), label: "Completed")

• Displays a custom view's status HUD. And the UIImageView is on the left:

HUD.showStatus(to: view, mode: .custom(UIImageView(image: UIImage(named: "warning"))), label: "You have an unfinished task.") {
    $0.contentView.indicatorPosition = .leading
}

• Sets the animation that should be used when showing and hiding the HUD. E.g. style, duration, spring damping:

HUD.showStatus(to: view, using: .animation(.slideUpDown, damping: .default, duration: 0.3), label: "Wrong password")

• Enable keyboard layout guide to track the keyboard's position in your app’s layout:

HUD.showStatus(to: view, label: "You have a message.") {
    $0.keyboardGuide = .center()
}

Warning

HUD is a UI class and should therefore only be accessed on the main thread.

For more examples, including how to use the HUD with asynchronous operations such as URLSession, and how to customize the HUD style, take a look at the bundled example project. Extensive API documentation is available here.

To run the example project, first clone the repo, then cd to the root directory and run pod install. Then open HUD.xcworkspace in Xcode.

Why the name FlyHUD?

The name FlyHUD combines Fly and HUD and stands out for its simplicity and expressiveness. Fly implies fast, efficient and flexible meaning, which is consistent with the real-time and immediacy of HUD. Overall, FlyHUD expresses the ability of HUD to present information and data quickly and efficiently.
