macOS my application is not invoking "applicationDidFinishLaunching: " method

[vnraju]

in my application....is unable to invoke
applicationDidFinishLaunching: method.........
suggestions plzzzzzz......

Would you care to elaborate on that? Your application should not invoke that method: NSApplication will invoke it automatically on it's delegate if it:

a) has a delegate

and

b) the delegate responds to that message.

It's a good idea to use [ code ] (without the spaces) tags around your code to prevent the insertion of

That method only gets called if the object that it is a member of is instantiated and set as the NSApplication delegate. Are you doing that (if so where). Personally I normally create an instance of my application delegate and connect it in MainMenu.nib.

what is the code to connect that function to a delegate.
How to declare a delegata and connect it to a function?
Can you please let me know.

The first question makes no sense. You do not connect "functions" (which are really called methods) to delegates

A delegate is simply an instance of an object. So you create a new class that implements the required methods.

You can then either create an instance of this object in your code and connect it to another object via the setDelegate: method, or you can instantiate this class in your nib and connect it there via the normal connection dragging method.

All of this is covered in any basic Cocoa introduction/tutorial.

I suggest you start reading

Outside of Delegate?

Is there a way to use this method outside of a delegate?

You can subscribe to NSApplicationDidFinishLaunchingNotification notifications in any class.
