Question

iOS :
I have app that open some content and i have added button on a right Navigation bar that can delete message content from saved catch, Now i want to put conformation action that conform with user before deleting message,
I have created UIActionsheet like this:

sheet = [[UIActionSheet alloc] initWithTitle:@"Delete Message" delegate:self cancelButtonTitle:@"Cancel"   destructiveButtonTitle:@"Delete Message" otherButtonTitles:nil];
 // view sheet 
 [sheet showInView:self.view];
 NSLog(@"Button %d", buttonIndex);

Now how can i use this value in my deleteContent function?
My delete function is

-(void) deleteContent 
{
   if (buttonIndex=0)
     {
      [[NSFileManager defaultManager] removeItemAtPath:fileName error:&e];
     }
}

My question is how can i rearrange this in just one function that can be called in one call and does all of this.

That’s not the way to do it. Call a function from the button in your nav bar to present the action sheet. Then implement the UIActionSheetDelegate method actionSheetDidDismissWithButtonIdex to take car of your actual deletion.

EDIT: If you need to pass the identity of the item to delete from the method that causes the action sheet to be presented, just add a parameter to you presentActionSheet method and pass the item.
