initialise nsviewcontroller which is implicitly called by nswindowcontroller

Question

In a cocoa application i have created a storyboard with one nswindowcontroller to control window and onew nsviewcontroller to control view. That view contain several buttons. The implicit call flow of these methods is like:

1. instantiating nswindowcontroller from calling method
2. implicit call to init method of nswindowcontroller
3. implicit call to init method of nsviewcontroller

Now what i required to display some buttons from those several buttons on behalf of some parameters which is needed to send to the nsviewcontrollerclass. Can anyone please help me to achieve this.

Answer 1

You will need to keep outlets to these buttons in your view controller. And depending on your business logic, you need to ensure, which button should be shown/hidden.

You can write a setUpButtons() function in the view controller. And the view controller can have an attribute or attributes to hold the parameter/s. Whenever you set these parameters, you need to call the setUpButtons() method to do the required showing/hiding of buttons.
