Quick use of MASShortcut framework on Swift project

Question

I am having trouble implementing MASShortcut (docs here) in a Swift OSX project to listen for global hotkeys. I have managed to import the framework via CocoaPods, and I have a working MASShortcutView instance:

@IBOutlet weak var testShortcutView:MASShortcutView!

I also figured out how to monitor and trigger something with the shortcut (please tell me if this is correct):

let shortcut = MASShortcut(keyCode: keycode, modifierFlags: modifierkeys)

MASShortcutMonitor.sharedMonitor().registerShortcut(shortcut, withAction: callback)

---

The question here is, how can I get the keyCode and modifierFlags from my MASShortcutView?

---

I really thank you in advance, I searched everywhere and I can't find an example on how to do this on swift. All I can find is is objective-c, and I can't figure it out.

Answer 1

Following code will register shortcut handler for Cmd+Shift+K key combination

let shortcut = MASShortcut.init(keyCode: UInt(kVK_ANSI_K), modifierFlags: UInt(NSEventModifierFlags.CommandKeyMask.rawValue + NSEventModifierFlags.ShiftKeyMask.rawValue))

MASShortcutMonitor.sharedMonitor().registerShortcut(shortcut, withAction: {
    print("Hello world")
})

Cmd and Shift - modifing keys. You should set them in the modifierFlags parameters. Full list of possible values is available in NSEventModifierFlags enum.

For your convenience I have placed sample project on github:

https://github.com/melifaro-/ShortCutSwiftSample

That handles shortcuts changes:

shortcutView.shortcutValueChange = { (sender) in

    let callback: (() -> Void)!

    if self.shortcutView.shortcutValue.keyCodeStringForKeyEquivalent == "k" {
        callback = {
            print("K shortcut handler")
        }
    } else {
        callback = {
            print("Default handler")
        }
    }

    MASShortcutMonitor.sharedMonitor().registerShortcut(self.shortcutView.shortcutValue, withAction: callback)
}

I have pushed changes into the repo. I would recommend to try following scenario:

Using the shortcut view:

1. Set Cmd+Shift+K shortcut

2. Set Cmd+Shift+J shortcut

3. Try this shortcuts - different callbacks should be performed

Hope it helps.
