macOS NSComboBox - How to know item selected or not

[satyam90]

I am using Obj C with Cocoa Frame work.
I have a NSComboBox in my application where I am populating the contents using the method "addItemWithObjectValue" in awakeFromNib. I am adding 5 entries to the combo box. Its working fine. But I can see the entries only when I click on the combo box for selection. By default no entry is shown and selected.
If we can't show any default value in combo box, how to validate whether any value is selected or not?

Is there any solution for this?

Just select the first item as the default item using selectItemAtIndex:0

Did you look at the documentation?

There are very obvious methods for selecting an item and checking which item is selected.
