willPresentActionSheet two different action sheets in one class. How to know which one will present

In my class I need to have 2 different (or more) actionsheets. All of the sheets go to willPresentActionSheet. In willPresentActionShee开发者_如何学Got I do things like add a datepicker. But how do I know which actionsheet called the willPresentActionSheet?

EDIT: I created the actionsheet like this:

UIActionSheet *asheet = [[UIActionSheet alloc] 
                         initWithTitle:@"Pick a value" 


                         delegate:self
                         cancelButtonTitle:@"Cancel" 
                         destructiveButtonTitle:nil 
                         otherButtonTitles:@"Select"
                         , nil];

[asheet showInView:[self.view superview]]; 

[asheet setFrame:CGRectMake(0, 117, 320, 383)];
[asheet release];

You can set the 'tag' for the action sheets, and check the tag in willPresentActionSheet: method. Simple!

Edit: Set the tag.

actionSheet1.tag = 100;
actionSheet2.tag = 101;

And in willPresentActionSheet: method.

if (actionSheet.tag == 100) {  
    // actionSheet1 is going to be presented
} else if (actionSheet.tag == 101) {
    // actionSheet2 is going to be presented
}

It passes the actionsheet into the method... So if you have (declared in the header) actionView1 and actionView2 then you can do...

if([actionSheet isEqual:actionView1]) {
  // do stuff for 1
} else if([actionSheet isEqual:actionView2]) {
  // do stuff for 2
}
