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.

• iOS 5.0 or higher

• Automatic Reference Counting (ARC)

• UIKit.framework

• Foundation.framework

• CoreGraphic.framework

• QuartzCore.framework

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.

It has following built-in animations.

• Fade animation.

• Fade with zoom animation.

You can even customize animation by subclassing HTProgressHUDAnimation.

You can install HTProgressHUD with CocoaPods.

1. Add a line for HTProgressHUD to your Podfile.

   pod 'HTProgressHUD', '~> 0.2.1'

2. Run install or update command.

   pod install

3. import HTProgressHUD

   #import <HTProgressHUD/HTProgressHUD.h>

You can add HTProgressHUD as a static library

1. Clone or download HTProgressHUD

2. Delete .git & .gitignore if exists

3. Delete Examples folder if you want

4. Move the HTProgressHUD folder into the you project's folder

5. From within Xcode, Open your project or workspace & add HTProgressHUD.xcodeproj

6. HTProgressHUD should appear in the Xcode Project Navigator

7. Click on the Your Project entry, Targets → Your Target → Build Phases → Target Dependencies → + “HTProgressHUD”

8. Click on the Your Project entry, Targets → Your Target → Build Phases → Link Binary with Libraries + libHTProgressHUD.a

9. Click on the Your Project entry, Targets → Your Target → Build Settings → Search Paths → User Header Search Paths → + HTProgressHUD's path

10. Click on the Your Project entry, Targets → Your Target → Build Settings → Linking → Other Linker Flags → + -ObjC

11. Done

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

• HTProgressHUDPieIndicatorView.m

• HTProgressHUDRingIndicatorView.h

• HTProgressHUDRingIndicatorView.m

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

__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.

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

1. MBProgressHUD is useful.

2. But it causes so many crashes.

3. So I reinvented the wheel.
