Terminating an application when closing the window

Question

I'm a little bit new to Objective-c with xCode, and I would like to know something. Is there a way to terminate an application when the red circle in the left of the window is clicked? Like on the calculator.

Answer 1

Yes you can do with Mac OSX applications.

You need to implement this method in your AppDelegate class

 - (BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)sender{
    return YES;
}
