ios 9 iphone 6S Play Haptic feedback or vibrate

Question

After user does force touch, I want to vibrate phone just like default behaviour.

Is it haptic? If so, how shall I do?

Answer 1

Example in Swift (for iPhone 6S)

import AudioToolbox

AudioServicesPlaySystemSound(1519) // Actuate `Peek` feedback (weak boom)
AudioServicesPlaySystemSound(1520) // Actuate `Pop` feedback (strong boom)
AudioServicesPlaySystemSound(1521) // Actuate `Nope` feedback (series of three weak booms)

Just in case - here're examples for iPhone 7/7+.

As for the force touch - you need to detect if it's available first:

func is3dTouchAvailable(traitCollection: UITraitCollection) -> Bool {
    return traitCollection.forceTouchCapability == UIForceTouchCapability.available
}

and then in touch events, it will be available as touch.force

func touchMoved(touch: UITouch, toPoint pos: CGPoint) {
    let location = touch.location(in: self)
    let node = self.atPoint(location)

    //...
    if is3dTouchEnabled {
        bubble.setPressure(pressurePercent: touch.force / touch.maximumPossibleForce)
    } else {
        // ...
    }
}

Starting with iOS 10, there is a new public API for handling haptic feedback: UIFeedbackGenerator.

let generator = UINotificationFeedbackGenerator()
generator.notificationOccurred(.success)

It is suggested to call .prepare() before using the generator and sending the feedback as there is a slight delay between the two due to the feedback hardware requiring a "wakeup". This could be done in viewDidLoad() or something comparable if you are expecting the feedback to be given shortly after.

See this blog for a good explanation of the new API and the available feedbacks:

For iOS 9 and older, you could use AudioToolBox as outlined in the other posts.

import AudioToolbox

private let isDevice = TARGET_OS_SIMULATOR == 0

func vibrate() {
    if isDevice {
        AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
    }
}

There are different feedback types. Try each one to figure out what is better for your needs:

// 1, 2, 3
let generator = UINotificationFeedbackGenerator()
generator.notificationOccurred(.error)
generator.notificationOccurred(.success)
generator.notificationOccurred(.warning)

// 4
let generator = UIImpactFeedbackGenerator(style: .light)
generator.impactOccurred()

// 5
let generator = UIImpactFeedbackGenerator(style: .medium)
generator.impactOccurred()

// 6
let generator = UIImpactFeedbackGenerator(style: .heavy)
generator.impactOccurred()

// 7
let generator = UISelectionFeedbackGenerator()
generator.selectionChanged()
