best to create your own UIViewController
make the view controller the same size as the page to block other touches and make it transparent so it looks like an alert view.
Make it so that instead of your function calling an alert, it loads your new View controller
This is a good example of an animation for your UIViewController to make it act like a typical IOS AlertView
-(void)initialDelayEnded {
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);
self.view.alpha = 1.0;
[UIView animateWithDuration:kTransitionDuration/1.5 animations:^{
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.1, 1.1);
}completion:^(BOOL complete){
[UIView animateWithDuration:kTransitionDuration/2 animations:^{
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);
}completion:^(BOOL complete){
[UIView animateWithDuration:kTransitionDuration/2 animations:^{
self.view.transform = CGAffineTransformIdentity;
}];
}];
}];
}
