Your question is not very clear. but I think UIActionSheet is what you need.
Edit
You can try this out
Set this in un .h file the the delegate like this
@interface NameOfYourClass : UIViewController <UIActionSheetDelegate>
And add this code in un .m File
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Action Sheet" delegate:self cancelButtonTitle:@"Cancel Button" destructiveButtonTitle:@"Destructive Button" otherButtonTitles:@"Other Button 1", @"Other Button 2", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheet showInView:self.view];
Edit2
So here's what to do to add a textfield to your allertview
UIAlertView *newAlert =[[UIAlertView alloc] initWithTitle:@"ADD item" message:@"Put it blank textfield will cover this" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
UITextField *newTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
newTextField.text=@"";
[newTextField setBackgroundColor:[UIColor whiteColor]];
[newTextField setKeyboardAppearance:UIKeyboardAppearanceAlert];
[newTextField setAutocorrectionType:UITextAutocorrectionTypeNo];
[newTextField setTextAlignment:UITextAlignmentCenter];
[newAlert addSubview:newTextField];
[newAlert show];
