Adding a combo box or drop-down list to UIView

问题:

I need to add a combo box or drop-down list to a UIView. I did not find such an object in the "Library" of the interface builder. How do I add this object to my UIVIEW? Do I have to inherit it from another object (which one?) or do I have to create it from scratch programmatically? Please help !!!

回答1:

The standard practice here is to either use a UIPicker or push a TableViewController to the stack and return once the user has selected an option here.

Youll prolly want to use the UIPicker class as there is no DropDown in UIKit, you can always make your own dropdown list if you desire
