This class make it easier to use UIAlertView with 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 in the same object (as in such case, it is not easy to have a clean code if you share the same delegate)

[OHAlertView showAlertWithTitle:@"Alert Demo"
message:@"You like this sample?"
cancelButton:@"No"
okButton:@"Yes"
buttonHandler:^(OHAlertView* alert, NSInteger buttonIndex)
{
NSLog(@"button tapped: %d",buttonIndex);
if (buttonIndex == alert.cancelButtonIndex) {
NSLog(@"No");
} else {
NSLog(@"Yes");
}
}];
You can also use this class to generate an AlertView that will be dismissed after a given time. (You can even add a dynamic text on your alert to display the live countdown)
[[[OHAlertView alloc] initWithTitle:@"Alert Demo"
message:@"This is a demo message"
cancelButton:nil
otherButtons:[NSArray arrayWithObject:@"OK"]
buttonHandler:^(OHAlertView* alert, NSInteger buttonIndex)
{
if (buttonIndex == -1)
{
self.status.text = @"Demo alert dismissed automatically after timeout!";
}
else
{
self.status.text = @"Demo alert dismissed by user!";
}
}] showWithTimeout:12 timeoutButtonIndex:-1 timeoutMessageFormat:@"(Alert dismissed in %lus)"];
