HTProgressHUD

HTProgressHUD is an replacement for UIProgressHUD, the undocumented UI component in iOS.
And it is also replacement for MBProgressHUD.
MBProgressHUD is too old, and causes so many crashes.
So I re-implemented it, with newer-APIs, more stability and more customizabilities.

Requirements

iOS SDK

iOS 5.0 or higher
Automatic Reference Counting (ARC)

Frameworks

UIKit.framework
Foundation.framework
CoreGraphic.framework
QuartzCore.framework

Specifications

Indicators

It has following built-in indicators.

Indicator with UIActivityIndicatorView.

Indicator with large white UIActivityIndicatorView.
Pie-chart like indicator.

Indicator that shows progress with pie-chart like component.
Ring-shaped indicator.

Indicator that shows progress with ring shaped component.

And you can also customize indicator by subclassing HTProgressHUDIndicatorView.

Animations

It has following built-in animations.

Fade animation.
Fade with zoom animation.

You can even customize animation by subclassing HTProgressHUDAnimation.

Installation

CocoaPods

You can install HTProgressHUD with CocoaPods.

Add a line for HTProgressHUD to your Podfile.

pod 'HTProgressHUD', '~> 0.2.1'
Run install or update command.

pod install
import HTProgressHUD

#import <HTProgressHUD/HTProgressHUD.h>

As a Static Library

You can add HTProgressHUD as a static library

Clone or download HTProgressHUD
Delete .git & .gitignore if exists
Delete Examples folder if you want
Move the HTProgressHUD folder into the you project's folder
From within Xcode, Open your project or workspace & add HTProgressHUD.xcodeproj
HTProgressHUD should appear in the Xcode Project Navigator
Click on the Your Project entry, Targets → Your Target → Build Phases → Target Dependencies → + “HTProgressHUD”
Click on the Your Project entry, Targets → Your Target → Build Phases → Link Binary with Libraries + libHTProgressHUD.a
Click on the Your Project entry, Targets → Your Target → Build Settings → Search Paths → User Header Search Paths → + HTProgressHUD's path
Click on the Your Project entry, Targets → Your Target → Build Settings → Linking → Other Linker Flags → + -ObjC
Done

As source files

Copy following files into your project.

HTProgressHUD.h
HTProgressHUD.m
HTProgressHUDAnimation.h
HTProgressHUDAnimation.m
HTProgressHUDFadeAnimation.h
HTProgressHUDFadeAnimation.m
HTProgressHUDFadeZoomAnimation.h
HTProgressHUDFadeZoomAnimation.m
HTProgressHUDIndicatorView.h
HTProgressHUDIndicatorView.m
HTProgressHUDPieIndicatorView.h

HTProgressHUDRingIndicatorView.h
HTProgressHUDRingIndicatorView.m

Usages

Example

HTProgressHUD *HUD = [[HTProgressHUD alloc] init];
[HUD showInView:self.view];
[HUD hideAfterDelay:3];

More Complex Example

__block HTProgressHUD *progressHUD = [[HTProgressHUD alloc] init];
progressHUD.animation = [HTProgressHUDFadeZoomAnimation animation];
progressHUD.indicatorView = [HTProgressHUDIndicatorView indicatorViewWithType:HTProgressHUDIndicatorTypePie];
progressHUD.text = @"Loading...";

[progressHUD showWithAnimation:YES inView:self.view whileExecutingBlock:^{
    float r = 0.01;
    for (int i = 0; i <= 1 / r; i++) {
        [NSThread sleepForTimeInterval:r];
        progressHUD.progress = i * r;
        if (progressHUD.progress > 0.5) {
            progressHUD.text = @"Almost done";
        }
    }
}];

or See HTProgressHUDExample Project.

Customization

See the source of built-in animations and built-in indicators. These are also kind of customized animations/indicators.

Three-line Summary

MBProgressHUD is useful.
But it causes so many crashes.
So I reinvented the wheel.
