Solution 2:

I beleive you shouldn't use dropdown boxes in iOS, as it's a desktop OS UI control element. You should think up something else using existing components (like PickerView), that's the words for UI consistency.

And if you need this anyway, you may create a table view, place it beneath your label and a triangular button(which causes it to appear and disappear) and populate it with values.

Solution 3:

Since there are no native DropDown elements in iOS, you could make use of a TextField with custom background and a UITableView to accomplish that. Here is how to go about it.

Pseudocode

• Create a TextField and set it's delegate to parent controller
• Implement UITextFieldDelegate and implement the textFieldShouldBeginEditing method
• Create a new UIViewController and implement UITableView in it programmatically.
• Create a custom protocol and create it's object (delegate) it.
• In textFieldShouldBeginEditing method, load this controller and present it modally passing the required table's data source and set delegate as parent.
• in the new tableViewController, implement UITableViewDelegate and implement the didSelectRowAtIndex path method.
• Upon row selection, call the delegate with passing appropriate data.
• dismiss the modally presented controller.

Solution 4:

just for whom searching for small simple swift combo box here in 2016 year, i've tried a few of old and new (but obj-c) libs, and at last selected this:
