URBAlertView is a block-based alternative to the default UIAlertView available in UIKit that offers easier customization and a wider range of presentation and dismissal animations (fade, zoom, slide, flip, tumble).

To use URBAlertView in your own project, just import URBAlertView.h and URBAlertView.m files into your project, and then include "URBAlertView.h" where needed, or in your precompiled header.

The project uses ARC and targets iOS 5.0+.

The process of displaying an alert is very similar to that of UIKit's UIAlertView, except that you can use block for handling button events instead of the cumbersome delegate method. Just create an instance of URBAlertView, add some buttons and show (or show with a specific presentation style):

URBAlertView *alertView = [URBAlertView alloc] initWithTitle:@"Test Dialog" subtitle:@"This is just a test dialog"];
[alertView addButtonWithTitle:@"Close"];
[alertView addButtonWithTitle:@"OK"];
[alertView setHandlerBlock:^(NSInteger buttonIndex, URBAlertView *alertView) {
	[self.alertView hideWithCompletionBlock:^{
		NSLog(@"Alert view closed.");
	}];
}];
[self.alertView showWithAnimation:URBAlertAnimationFlipHorizontal];

By default, the dismissal animation will be in the same style as the presentation animation, unless you specifically use a different animation style when hiding:

[alertView hideWithAnimation:URBAlertAnimationTumble];

• Update to better resemple the init methods found in UIAlertView.
• Support for defining event handling blocks for each button instead of a single block for all buttons.
• UIAppearance conformance to allow for easier skinning and styling.
• Support for setting the UIImage instances to use for backgrounds and buttons without having to edit the core classes.
• Support for dynamically swapping out the content view without having to display another alert view.
