Improper setup of window displayed through menu item?

I am working on my first native mac app after playing with iOS for a while.

I am attempting to launch a window from a menu item, but I suspect I am doing it wrong. Any IBAction I connect to buttons on this new window returns an error.

Here is what I am doing. From a menu item I launch this:

-(IBAction)displaySAInput:(id)sender{

NSLog(@"Input selected.");
inputSAViewController = [[NSWindowController alloc] initWithWindowNibName:@"InputViewController"];
[inputSAViewController showWindow:self];

This launches the InputViewController nib that is owned by the InputViewController class. I set the InputViewController class to inherit from NSWindowController.

On InputViewController.m I have tested IBActions such as:

-(IBAction)testButton:(id)sender{

NSLog(@"Data recalled?");

}

I connect this IBAction to a button through the Interface Builder. All looks okay.

When I build and open the InputViewController window I receive this error in the console before clicking anything:

Could not connect the action testButton: to target of class NSWindowController

I have searched extensively but my ignorance prevents me from connecting the dots. This thread based on a similar error with NSApplication looks promising, but I don't quite understand what I'd need to make the connections happen related to the NSWindowController error.

This should be simple. What am I missing?

Your code:

-(IBAction)displaySAInput:(id)sender{
    NSLog(@"Input selected.");
    inputSAViewController = [[NSWindowController alloc]
                  initWithWindowNibName:@"InputViewController"];
    [inputSAViewController showWindow:self];
}

Notice you are alloc/initing a generic instance of NSWindowController, not your custom subclass where you've implemented the testButton: method. I assume you'd likely want that changed to:

-(IBAction)displaySAInput:(id)sender{
    NSLog(@"Input selected.");
    inputSAViewController = [[InputViewController alloc]
                  initWithWindowNibName:@"InputViewController"];
    [inputSAViewController showWindow:self];
}

Just load the NSWindow before hand and make it invisible and when the IBAction is called, just do the following:

[myWindow setIsVisible:YES];
[myWindow setLevel:NSFloatingWindowLevel];

Yay!
