MBProgressHUD is an iOS drop-in class that displays a translucent HUD with an indicator and/or labels while work is being done in a background thread. The HUD is meant as a replacement for the undocumented, private UIKit UIProgressHUD with some additional features.

Requirements

MBProgressHUD works on iOS 9.0+. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

You will need the latest developer tools in order to build MBProgressHUD. Old Xcode versions might work, but compatibility will not be explicitly maintained.

Adding MBProgressHUD to your project

CocoaPods

CocoaPods is the recommended way to add MBProgressHUD to your project.

  1. Add a pod entry for MBProgressHUD to your Podfile pod 'MBProgressHUD', '~> 1.2.0'
  2. Install the pod(s) by running pod install.
  3. Include MBProgressHUD wherever you need it with #import "MBProgressHUD.h".

Carthage

  1. Add MBProgressHUD to your Cartfile. e.g., github "jdg/MBProgressHUD" ~> 1.2.0
  2. Run carthage update
  3. Follow the rest of the standard Carthage installation instructions to add MBProgressHUD to your project.

SwiftPM / Accio

  1. Add the following to your Package.swift:
    .package(url: "https://github.com/jdg/MBProgressHUD.git", .upToNextMajor(from: "1.2.0")),
  2. Next, add MBProgressHUD to your App targets dependencies like so:
    .target(name: "App", dependencies: ["MBProgressHUD"]),
  3. Then open your project in Xcode 11+ (SwiftPM) or run accio update (Accio).

Source files

Alternatively you can directly add the MBProgressHUD.h and MBProgressHUD.m source files to your project.

  1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
  2. Open your project in Xcode, then drag and drop MBProgressHUD.h and MBProgressHUD.m onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.
  3. Include MBProgressHUD wherever you need it with #import "MBProgressHUD.h".

Static library

You can also add MBProgressHUD as a static library to your project or workspace.

  1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
  2. Open your project in Xcode, then drag and drop MBProgressHUD.xcodeproj onto your project or workspace (use the "Product Navigator view").
  3. Select your target and go to the Build phases tab. In the Link Binary With Libraries section select the add button. On the sheet find and add libMBProgressHUD.a. You might also need to add MBProgressHUD to the Target Dependencies list.
  4. Include MBProgressHUD wherever you need it with #import <MBProgressHUD/MBProgressHUD.h>.

Usage

The main guideline you need to follow when dealing with MBProgressHUD while running long-running tasks is keeping the main thread work-free, so the UI can be updated promptly. The recommended way of using MBProgressHUD is therefore to set it up on the main thread and then spinning the task, that you want to perform, off onto a new thread.

[MBProgressHUD showHUDAddedTo:self.view animated:YES];
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
	// Do something...
	dispatch_async(dispatch_get_main_queue(), ^{
		[MBProgressHUD hideHUDForView:self.view animated:YES];
	});
});

You can add the HUD on any view or window. It is however a good idea to avoid adding the HUD to certain UIKit views with complex view hierarchies - like UITableView or UICollectionView. Those can mutate their subviews in unexpected ways and thereby break HUD display.

If you need to configure the HUD you can do this by using the MBProgressHUD reference that showHUDAddedTo:animated: returns.

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeAnnularDeterminate;
hud.label.text = @"Loading";
[self doSomethingInBackgroundWithProgressCallback:^(float progress) {
	hud.progress = progress;
} completionCallback:^{
	[hud hideAnimated:YES];
}];

You can also use a NSProgress object and MBProgressHUD will update itself when there is progress reported through that object.

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeAnnularDeterminate;
hud.label.text = @"Loading";
NSProgress *progress = [self doSomethingInBackgroundCompletion:^{
	[hud hideAnimated:YES];
}];
hud.progressObject = progress;

Keep in mind that UI updates, including calls to MBProgressHUD should always be done on the main thread.

If you need to run your long-running task in the main thread, you should perform it with a slight delay, so UIKit will have enough time to update the UI (i.e., draw the HUD) before you block the main thread with your task.

[MBProgressHUD showHUDAddedTo:self.view animated:YES];
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 0.01 * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
	// Do something...
	[MBProgressHUD hideHUDForView:self.view animated:YES];
});

You should be aware that any HUD updates issued inside the above block won't be displayed until the block completes.

For more examples, including how to use MBProgressHUD with asynchronous operations such as NSURLConnection, take a look at the bundled demo project. Extensive API documentation is provided in the header file (MBProgressHUD.h).

MBProgressHUD
What is this?MBProgressHUD is an iOS drop-in class that displays a translucent HUD with an indicator and/or labels over your UI while work runs on a background thread.
Is it a library I add to my app's code, or something that runs on its own?It's a library — essentially one Objective-C class (MBProgressHUD.h/.m) you drop into an iOS project. It works on iOS 9.0+ and needs only Apple frameworks that Xcode templates already include.
How do I add it to my project?CocoaPods is the recommended way: add pod 'MBProgressHUD', '~> 1.2.0' to your Podfile and run pod install. Carthage, SwiftPM/Accio, dragging the two source files into Xcode, or adding it as a static library also work.
Do I need any third-party dependencies first?No — it depends only on Foundation, UIKit and CoreGraphics, which ship with Xcode templates. You do need current developer tools: old Xcode versions might work but compatibility isn't explicitly maintained.
Any gotchas when showing the HUD?Keep the main thread work-free: set the HUD up on the main thread and move your long-running task onto a background thread. Also avoid adding it to UITableView or UICollectionView, whose subview mutations can break HUD display.
Does MBProgressHUD collect any user data?No, the SDK does not collect any data.
Can it show real progress, not just a spinner?Yes — hand it an NSProgress object and the HUD updates itself as progress is reported through it. You can also use the reference returned by showHUDAddedTo:animated: to configure the HUD.
Why use this instead of UIKit's built-in progress view?UIKit's own UIProgressHUD is private and undocumented, so there is no supported built-in equivalent. MBProgressHUD was written as a supported replacement with some additional features.
Where are the docs and sample code?Extensive API documentation lives in the header file (MBProgressHUD.h), and the bundled demo project shows examples, including using the HUD with asynchronous operations like NSURLConnection.
Can I use it from Swift?Yes — it's an Objective-C class you import into Swift projects, and SwiftPM is one of the supported package managers alongside CocoaPods and Carthage.
What are similar projects?SVProgressHUD, FSCalendar, DZNEmptyDataSet, SkeletonView, pop, Spring, AFNetworking, chameleon
Which topics is it in?cocoa, swift-package-manager, objective-c, xcode, swift, ui-components, mobile, ui, ios, gui, library, mit
