@pooja i suggest u to use UIAlertViewfor that in your code where you are using UIActionSheetdelete button on delete button action call this..
@pooja 我建议你UIAlertView在你的代码中使用它，你UIActionSheet在删除按钮操作上使用删除按钮调用这个..
UIAlertView *updateAlert = [[UIAlertView alloc] initWithTitle: @"Item Deletion" message: @"Do u really want to delete" delegate: self cancelButtonTitle: @"YES" otherButtonTitles:@"NO",nil];
[updateAlert show];
[updateAlert release];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==0)
{
//give deletion code here
}
}
and do forgot to call UIActionSheetDelegate...
Hope this will help u!!!!
忘记打电话了UIActionSheetDelegate......希望这会帮助你！！！！

You need to put an alert view for this purpose.When the button at index 0,1 is pressed perform the desired action.You will have to put this alert view when the user presses the delete button of the Action Sheet.
为此，您需要放置一个警报视图。当按下索引 0,1 处的按钮时，执行所需的操作。当用户按下操作表的删除按钮时，您必须放置此警报视图。
