Mouse Down (NSEvent in Swift 2)

As I continue adding features for my upcoming app I’m starting to work with NSEvents to add actions to user interaction. I’ve been amazed at how fast is to do this in Swift. 

For instance, detecting where the user presses a button in your window, and then converting it to the coordinate system of a view is extremely easy. Just type the following within your NSView class:

override func mouseDown(theEvent : NSEvent) {

        Swift.print(“Original: \(theEvent.locationInWindow)”)

        let convertedPoint = self.convertPoint(theEvent.locationInWindow, fromView: theEvent.window?.contentView)

        Swift.print(“Tuned: \(convertedPoint)”)



Easy as pie!

Switching NSViewControllers from NSWindowController

This has taken quite some time to crack as there was not that much available information online. 

I wanted a very simple way to change the NSViewController of a window on the fly by using code.

The solution I ended up with is quite easy, on the NSWindowController I load the default NSViewController by typing in windowDidLoad():

let viewController = storyboard?.instantiateControllerWithIdentifier(“nsviewcontroller1″) as! NSViewController

        self.window?.contentViewController = viewController

Afterwards, when I want to change NSViewController1 by NSViewController2 i just have a button in my toolbar linked to the following action:

@IBAction func showController2(sender: NSToolbarItem){

        let viewController = storyboard?.instantiateControllerWithIdentifier(nsviewcontroller2) as! NSViewController

        self.window?.contentViewController = viewController


That’s about it, extremely simple, but took me quite a bit to develop.
