在UIScrollView中，ComboBox不起作用

I have set up this combo box and it works great. Now I have a scene that needs to scroll down and I have implemented a scroll view that takes up the entire scene. I have 4 of these combo boxes on the scene and I can't get them working properly. In my ViewController.m if I change the "self.view addSubview" to "self.theScroller addSubView" I can get the ComboBox to load on the scroller, when clicked it throws up the normal keyboard and doesn't load the UIPickerView. and it works great
