make a toolBar by IBoutlet and set its y coordinate to 100 or more than view's height. then in particular action change y coordinate accordingly. this is done via animation.

You also use this with keyboard .

by using -(void) keyboardWillShow:(NSNotification *) note and -(void) keyboardWillHide:(NSNotification *) note

 UIToolBar *toolBar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,0,320,44)];
        [toolBar setBarStyle:UIBarStyleBlackOpaque];
        UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(doneBtnTapped:)];

        toolBar.items = [[NSArray alloc] initWithObjects:barButtonDone,nil];
        barButtonDone.tintColor=[UIColor blackColor];
        [popoverView addSubview:toolBar];

        [popoverView addSubview:pickerView];

I created a custom view and added a done button on that along with picker view.

Thanks
