iphone - Detect shake gesture IOS Swift

Question

I'm developing a app with a gesture system, basically if I turn the iPhone to left my app will do a function, if I turn the iPhone to Right, other function, with others gestures.

I don't have idea how to work with that, i'm trying search in google but not work, the result is only touch gesture and not motion gesture.

someone have a tutorial to help me?

Answer 1

Swift3 ios10:

override func viewDidLoad() {
    super.viewDidLoad()
    self.becomeFirstResponder() // To get shake gesture
}

// We are willing to become first responder to get shake motion
override var canBecomeFirstResponder: Bool {
    get {
        return true
    }
}

// Enable detection of shake motion
override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
    if motion == .motionShake {
        print("Why are you shaking me?")
    }
}
