SVProgressHUD

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 (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:

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

SVProgressHUD requires at least Swift tools version 5.3.

From CocoaPods

CocoaPods 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:

pod 'SVProgressHUD'

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

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

This pulls from the master branch directly.

Second, install SVProgressHUD into your project:

pod install

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:

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.

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 add the following line to your Podfile:

use_frameworks!

If you added SVProgressHUD manually, just add a bridging header 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:

[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:

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:

+ (void)show;
+ (void)showWithStatus:(NSString*)string;

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

+ (void)showProgress:(CGFloat)progress;
+ (void)showProgress:(CGFloat)progress status:(NSString*)status;

Dismissing the HUD

The HUD can be dismissed using:

+ (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.

+ (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.
