Creating first MAC application

The basic concepts in this are below: 

- The starting point is same as iOS application. i.e. File -> New Project , select the Mac OS X and Cocoa Application. 

- Save the project and just run it => It shows up the Empty Mac application. 

- the difference between iOS and Mac application is that the window is fully resizable. 

- Mac application can have more than one window, and can be minimised etc. 

The empty view that shows up when it is run is a Window. 

Now it is time to add views to it. This can be done in the below way. Inorder to do this, File / New File and give name something like FirstAppViewController. 

If the Controller is created with a xib file associated with it, then the components can be just dragged to the xib file

Even though now we created a new Cotnroller, it doesn't get added to the window automatically. Code like below needs to be added to the app delegate

self.firstAppViewController = [[FirstAppViewController alloc]initWithNibName:@"FirstAppViewController" bundle:nil];

    [self.window.contentView addSubview:self.firstAppViewController.view];

    self.firstAppViewController.view.frame = ((NSView*)self.window.contentView).bounds;

After this the application shown the window like below !!
