About these classes

These two classes make it easier to use UIAlertView and UIActionSheet classes by using blocks.

This allows you to provide directly the code to execute (as a block) in return to the tap on a button, instead of declaring a delegate and implementing the corresponding methods.

This also has the huge advantage of simplifying the code especially when using multiple UIAlertViews and UIActionSheets in the same object (as in such case, it is not easy to have a clean code if you share the same delegate)

Note: Blocks are a feature introducted in (and only compatible starting) iOS 4.x

Example

[OHAlertView showAlertWithTitle:@"Alert Demo"
                        message:@"You like this sample?"
                   cancelButton:@"No"
                       okButton:@"Yes"
                 onButtonTapped:^(OHAlertView* alert, NSInteger buttonIndex)
 {
     NSLog(@"button tapped: %d",buttonIndex);
 
     if (buttonIndex == alert.cancelButtonIndex) {
         NSLog(@"No");
     } else {
         NSLog(@"Yes");
     }
 }];

Note for iOS versions prior 4.0

This class is designed to be used with blocks, which are a new feature introduced in iOS 4.0.

To assure the compatibility with pre-iOS4, OHAlertView also propose the possibility to associate a userInfo dictionary to the AlertView, and specify a @selector to call on a given delegate, so that you can at least specify a different delegate method in case you have multiple OHAlertViews using the same delegate.
