Answer 1

Well this is how I use actionSheet ..

actionSheet  = [[UIActionSheet alloc] initWithTitle:nil 
                                                             delegate:nil
                                                    cancelButtonTitle:nil
                                               destructiveButtonTitle:nil
                                                    otherButtonTitles:nil];

[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];

CGRect pickerFrame = CGRectMake(0, 40, 0, 0);

UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;

[actionSheet addSubview:pickerView];
[pickerView release];

UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Done"]];
closeButton.momentary = YES; 
closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:@selector(dismissActionSheet) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:closeButton];
[closeButton release];

[actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];

[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];

Once you are done with this just define a selector in your .m like..

-(void)dismissActionSheet{
    [actionSheet dismissWithClickedButtonIndex:0 animated:YES]; 
}

so inside dismiss action sheet you can re-write what is happening inside bar button item... hope this helps.
