Answer 1

You are looking for UIAlertView controller.

Answer 2

I believe that you want UIActionSheet, which is what Apple Recommends for user choice:
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Some Message" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"button To Destroy or nil" otherButtonTitles:#"Choice 1", #"Choice 2", #"Choice 3", nil];

Answer 3

What you want to do is check which button is being clicked under otherButtonTitles:
Something like this:
UIAlertView *yourAlert = [[UIAlertView alloc] initWithTitle:#"Your title" message:#"Some String" delegate:self cancelButtonTitle:#"Dismiss" otherButtonTitles:#"Confirm",nil];
[yourAlert show];
And remember to set the delegate to self.
Then:
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0){
//'Dismissing' code here
}
if (buttonIndex == 1){
//Detecting whatever was under otherButtonTitles:
//Right now it's checking if the user clicked "Confirm" -> So here you can put whatever you need
NSLog(#"You clicked Confirm");
}
}
Under the conditionals, you are checking which button the user is clicking.
