How to get accelerometer data in IOS?

Question

I am using the UIAccelerotmeterDelegate method accelerometer:didAccelerate: but recently that method has been deprecated in iOS 5.0. So what is the alternative way

Answer 1

I am answering this for Swift 5.x.

@available(iOS, introduced: 2.0, deprecated: 13.0, message: "UIAcceleration has been replaced by the CoreMotion framework") public protocol UIAccelerometerDelegate : NSObjectProtocol { }

Don't conform to UIAccelerometerDelegate and add only CoreMotion framework.

import CoreMotion

If you want to show animation or create game , you can start with following code.

self.motionManager = CMMotionManager()
self.motionManager?.startAccelerometerUpdates()
if motionManager.isAccelerometerAvailable {          
  motionManager.startAccelerometerUpdates(to: .main) { (data, error) in
    if let myData = data {
        let x =  String(format: "%.3f",myData.acceleration.x)
        let y =  String(format: "%.3f",myData.acceleration.y)
        let z =  String(format: "%.3f",myData.acceleration.z)
    DispatchQueue.main.async { 
          var rect = self.anyObject.frame
         let movetoX = rect.origin.x + CGFloat(myData.acceleration.x * stepMoveFactor)
         let movetoY = rect.origin.y - CGFloat(myData.acceleration.y * stepMoveFactor)
         if ( movetoX > 0 && movetoX < SCREEN_WIDTH ) {
            rect.origin.x += CGFloat(myData.acceleration.x * stepMoveFactor)
         }
         if ( movetoY > 1 && movetoY < maxY ) {
           rect.origin.y -= CGFloat(myData.acceleration.y * stepMoveFactor) }
         }
    }
 }

}

use UIView.animate if you want. This method initiates a set of animations to perform on the view. The block object in the animations parameter contains the code for animating the properties of one or more views.
