How can i detect device orientation even if the orientation is locked

Question

我使用了磁力计，但它的值总是不同的。我想检测用户设备何时在横向位置处于水平平均值，并且在特定发布时想要执行某些操作。

Answer 1

In AppDelegate.swift inside the didFinishLaunchingWithOptions function put the below code :

NotificationCenter.default.addObserver(self, selector: #selector(AppDelegate.rotated), name: UIDevice.orientationDidChangeNotification, object: nil)

then inside the AppDelegate put the following function:

func rotated() {
    if UIDeviceOrientationIsLandscape(UIDevice.current.orientation) {
        print("Landscape")
    }

    if UIDeviceOrientationIsPortrait(UIDevice.current.orientation) {
        print("Portrait")
    }
}

hope it will work for you ... :)
