`SVProgressHUD` is a clean and easy-to-use HUD meant to display the progress of an ongoing task on iOS and tvOS.

## Installation

### Swift Package Manager

[Swift Package Manager](https://swift.org/package-manager/) (SwiftPM) is a tool for managing the distribution of Swift code. It simplifies the process of managing Swift package dependencies.

To integrate `SVProgressHUD` into your project using SwiftPM:

1. In Xcode, select **File > Add Package Dependency**.
2. Enter the following package repository URL: https://github.com/SVProgressHUD/SVProgressHUD.git
3. Choose the appropriate version (e.g. a specific version, branch, or commit).
4. Add `SVProgressHUD` to your target dependencies.

`SVProgressHUD` requires at least Swift tools version 5.3.

### From CocoaPods

[CocoaPods](http://cocoapods.org) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like `SVProgressHUD` in your projects. First, add the following line to your [Podfile](http://guides.cocoapods.org/using/using-cocoapods.html):

```ruby
pod 'SVProgressHUD'
```

If you want to use the latest features of `SVProgressHUD` use normal external source dependencies.

```ruby
pod 'SVProgressHUD', :git => 'https://github.com/SVProgressHUD/SVProgressHUD.git'
```

This pulls from the `master` branch directly.

Second, install `SVProgressHUD` into your project:

```ruby
pod install
```

### Carthage

[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate `SVProgressHUD` into your Xcode project using Carthage, specify it in your `Cartfile`:

```ogdl
github "SVProgressHUD/SVProgressHUD"
```

Run `carthage bootstrap` to build the framework in your repository's Carthage directory. You can then include it in your target's `carthage copy-frameworks` build phase. For more information on this, please see [Carthage's documentation](https://github.com/carthage/carthage#if-youre-building-for-ios-tvos-or-watchos).

### Manually

* Drag the `SVProgressHUD/SVProgressHUD` folder into your project.
* Take care that `SVProgressHUD.bundle` is added to `Targets->Build Phases->Copy Bundle Resources`.
* Add the **QuartzCore** framework to your project.

## Swift

Even though `SVProgressHUD` is written in Objective-C, it can be used in Swift with no hassle.

If you use [CocoaPods](http://cocoapods.org) add the following line to your [Podfile](http://guides.cocoapods.org/using/using-cocoapods.html):

```ruby
use_frameworks!
```

If you added `SVProgressHUD` manually, just add a [bridging header](https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html) file to your project with the `SVProgressHUD` header included.

## Usage

(see sample Xcode project in `/Demo`)

`SVProgressHUD` is created as a singleton (i.e. it doesn't need to be explicitly allocated and instantiated; you directly call `[SVProgressHUD method]` / `SVProgressHUD.method()`).

**Use `SVProgressHUD` wisely! Only use it if you absolutely need to perform a task before taking the user forward. Bad use case examples: pull to refresh, infinite scrolling, sending message.**

Using `SVProgressHUD` in your app will usually look as simple as this.

**Objective-C:**

```objective-c
[SVProgressHUD show];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
// time-consuming task
dispatch_async(dispatch_get_main_queue(), ^{
[SVProgressHUD dismiss];
});
});
```

**Swift:**

```swift
SVProgressHUD.show()
DispatchQueue.global(qos: .default).async {
// time-consuming task
DispatchQueue.main.async {
SVProgressHUD.dismiss()
}
}
```

### Showing the HUD

You can show the status of indeterminate tasks using one of the following:

```objective-c
+ (void)show;
+ (void)showWithStatus:(NSString*)string;
```

If you'd like the HUD to reflect the progress of a task, use one of these:

```objective-c
+ (void)showProgress:(CGFloat)progress;
+ (void)showProgress:(CGFloat)progress status:(NSString*)status;
```

### Dismissing the HUD

The HUD can be dismissed using:

```objective-c
+ (void)dismiss;
+ (void)dismissWithDelay:(NSTimeInterval)delay;
```

If you'd like to stack HUDs, you can balance out every show call using:

```
+ (void)popActivity;
```

The HUD will get dismissed once the `popActivity` calls will match the number of show calls.

Or show an image with status before getting dismissed a little bit later. The display time depends on `minimumDismissTimeInterval` and the length of the given string.

```objective-c
+ (void)showInfoWithStatus:(NSString*)string;
+ (void)showSuccessWithStatus:(NSString*)string;
+ (void)showErrorWithStatus:(NSString*)string;
+ (void)showImage:(UIImage*)image status:(NSString*)string;
```

## Customization

`SVProgressHUD` is designed with flexibility in mind, providing a myriad of customization options to fit the look and feel of your application seamlessly.

* Appearance: Make use of the `UI_APPEARANCE_SELECTOR` to adjust styles, colors, fonts, size, and images app-wide.
* Behavior: Control visibility durations, display delays, and animation speeds.
* Feedback: Enhance the user experience with options for haptic feedback and motion effects.

For a comprehensive list of properties and detailed explanations, refer to the `SVProgressHUD.h` file in the API documentation.

### Hint

As standard `SVProgressHUD` offers three preconfigured styles:

* `SVProgressHUDStyleAutomatic`: Automatically switch between the light and dark style
* `SVProgressHUDStyleLight`: White background with black spinner and text
* `SVProgressHUDStyleDark`: Black background with white spinner and text

If you want to use custom colors use `setForegroundColor:` and/or `setBackgroundColor:`. These implicitly set the HUD's style to `SVProgressHUDStyleCustom`.

## Haptic Feedback

Available on iPhone 7 and newer, `SVProgressHUD` can automatically trigger haptic feedback depending on which HUD is being displayed. The feedback maps as follows:

* `showSuccessWithStatus:` <-> `UINotificationFeedbackTypeSuccess`
* `showInfoWithStatus:` <-> `UINotificationFeedbackTypeWarning`
* `showErrorWithStatus:` <-> `UINotificationFeedbackTypeError`

To enable this functionality, use `setHapticsEnabled:`.

## Notifications

`SVProgressHUD` posts four notifications via `NSNotificationCenter` in response to being shown/dismissed:

* `SVProgressHUDWillAppearNotification` when the show animation starts
* `SVProgressHUDDidAppearNotification` when the show animation completes
* `SVProgressHUDWillDisappearNotification` when the dismiss animation starts
* `SVProgressHUDDidDisappearNotification` when the dismiss animation completes

Each notification passes a `userInfo` dictionary holding the HUD's status string (if any), retrievable via `SVProgressHUDStatusUserInfoKey`.

`SVProgressHUD` also posts `SVProgressHUDDidReceiveTouchEventNotification` when users touch on the overall screen or `SVProgressHUDDidTouchDownInsideNotification` when a user touches on the HUD directly. For these notifications `userInfo` is not passed but the object parameter contains the `UIEvent` that related to the touch.

## App Extensions

When using `SVProgressHUD` in an App Extension, `#define SV_APP_EXTENSIONS` to avoid using unavailable APIs. This will be done automatically when using the `AppExtension` CocoaPods subspec. Additionally, call `setViewForExtension:` from your extensions view controller with `self.view`.
