Cocoa Touch drop down box on iPad

I am implementing an iPad app that needs to make use of a drop down box or something to filter items in a tableview.

Can anyone suggest a开发者_如何学C control? I can't use the picker view (because you can't adjust height) and the segment view can't hold enough items.

In this instance, I'd be tempted to use a UIPicker view in an UIActionSheet. (Or other similar modal dialog.)

That said, it might be more appropriate to use a Search Controller to filter the UITableView. (Really depends on the application.)

Sounds like you could just use a Search Controller to me, is your data categorisable? You could be better off just creating a hierarchy and navigating through it using a Navigation Controller to move between tableviews.
