HAHud

HAHud is a small reusable piece of code that provides you with a configurable replacement to the UIAlertView concept. Its main features are:

• Large and variable size text
• Choice of activity viewer, progress bar, check/cross or buttons
• Any number of buttons
• Buttons side by side or stacked vertically
• Simple block-based callbacks
• Can be automatically dismissed after a specified interval

HAHud started as a replacement to ATMHud but is significantly simpler and more modern. It heavily utilises constraints, which makes it suited to iOS 7. However, do note that it doesn't currently use ARC but can be easily converted. After all, it is only a few hundred lines of code.

Installation

Drag the HAHud group into your project. It consists of the HAHud.h and HAHud.m files as well as a few images.

Usage

See the sample project's HAHUDViewController for sample usage.

Also see HAHud.h for more information.

The basic technique for a side-by-side 2-button alert is as follows:

HAHud * hud = [HAHud hudWithButtonTitles:@[@"Cancel", @"OK"] stacked:NO];
[hud setCompletion:^(NSUInteger bTag) {
    NSLog(@"You tapped button # %lu", (unsigned long)bTag);
}];
hud.message.text = msg;
hud.parentView = self.view;
[hud show];

Here's another with a progress bar:

HAHud * hud = [HAHud hudWithProgressRate:0.3f];
hud.message.text = msg;
hud.parentView = self.view;
[hud show];

// And later on in your code...
hud.progressView.progress = 0.7f;

// And still later...
hud.progressView.progress = 1.f;
[hud dismiss];

Notes

1. If you don't specify the parentView, the hud will show on the window. That works only in the default orientation. The window has no understanding of orientation changes, so the hud will show in the default orientation. To fix that, simply assign parentView to be the main view of your current view controller. The hud will then orient with your main view.

2. The hud will automatically dismiss itself when a button is tapped.

3. Do not try to reuse a HAHud object (for example showing it again inside the completion block of the button taps). You should have no expectation that the HAHud object is still alive after having configured and shown the hud. Simple create a new one whenever you need it.
