Depends, if this is on the iPad, you can use UIPopoverController and present a UITableViewController inside it.

If not, you can present a UIActionSheet and add UIPickerView or a UITableView inside it...in this example, I am creating a UIActionSheet and placing a UIPickerView inside it:

    NSString *title = UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) ? @"\n\n\n\n\n\n\n\n\n" : @"\n\n\n\n\n\n\n\n\n\n\n\n" ;
            UIActionSheet *actionSheet = [[UIActionSheet alloc] 
                                          initWithTitle:[NSString stringWithFormat:@"%@%@", title, [entry objectForKey:@"Name"]]
                                          delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Ok", nil];
[actionSheet setDelegate:self];
[actionSheet setTag:row];

pv = [[UIPickerView alloc] init];
[pv setShowsSelectionIndicator:YES];
[pv setDelegate:self];
[pv setTag:28];
[actionSheet addSubview:pv];
[actionSheet showInView:[[[self navigationController] tabBarController] view]];
[pv release];

Notice the "\n"s, you need those to make room for the Picker view. Here's the result:
