Best Answer-推荐答案

如果您需要检测设备是否为 iPhoneX，请不要使用 bounds，这取决于设备的方向。因此，如果用户以纵向模式打开您的应用程序，它将失败。您可以使用不会在旋转时更改的设备属性 nativeBounds。

In iOS 8 and later, a screen’s bounds property takes the interface orientation of the screen into account. This behavior means that the bounds for a device in a portrait orientation may not be the same as the bounds for the device in a landscape orientation. Apps that rely on the screen dimensions can use the object in the fixedCoordinateSpace property as a fixed point of reference for any calculations they must make. (Prior to iOS 8, a screen’s bounds rectangle always reflected the screen dimensions relative to a portrait-up orientation. Rotating the device to a landscape or upside-down orientation did not change the bounds.)

extension UIDevice {
    var iPhoneX: Bool {
        return UIScreen.main.nativeBounds.height == 2436
    }
}

用法

if UIDevice.current.iPhoneX { 
    print("This device is a iPhoneX")
}
