I want to create a combo box where user can only select items from the list. I have searched but not getting any right solution. Please let me know If anyone know, how to implement this in ios.
If I understand you correctly what you want is in my iOSKit. Look at the “Extensions.PickerView” control. An example of how to use it can be found in “Example Views/Missing Controls View” within the project. https://github.com/kingj5/iOSKit
You can also simulate a drop-down menu using a table that appears underneath a textfield (combobox) or a button (popup menu).
PickerView is the native way of doing it, but in some cases using a Table might be better.
