OrientationTracker is a Core Motion based library for tracking device orientation changes. It also works for devices with orientation-lock turned on. You can subscribe to orientation change notifications and react accordingly.

Requirements

  • iOS 8.0+
  • Xcode 10.2
  • Swift 5.0

Usage

To start device orientation tracking use OrientationTracker you simply invoke the startDeviceOrientationTracking method, preferably in AppDelegate :

DeviceOrientationDetector.shared.startDeviceOrientationTracking()

You then add an observer for the OrientationTracker.deviceOrientationChangedNotification and react to orientation changes:

NotificationCenter.default.addObserver(self, selector: #selector(updateViews), name: DeviceOrientationDetector.deviceOrientationChangedNotification, object: nil)

You can access the current orientation using the currentDeviceOrientation property.

To stop receiving notifications use the stopDeviceOrientationTracking method:

DeviceOrientationDetector.shared.stopDeviceOrientationTracking()

If your app supports portrait mode only, you can use the affineTransform property to rotate views when the orientation changes:

UIView.animate(withDuration: 0.2) {
    self.imageView.transform = DeviceOrientationDetector.shared.affineTransform
}

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods
