Swift, камера в ландшафтном режиме

Question

Я использую этот учебник, но у меня возникла проблема, когда в целевом целевом изображении отмены изображения, имитирующем мое приложение, которое работает только в ландшафте.

Как настроить эту камеру так, чтобы она работала только в ландшафтном режиме.

Просто сделайте если- тест для проверки ориентации устройства.

Что-то вроде

if UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeLeft || UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeRight 
{ 
    //Do the camera stuff 
} 
else 
{ 
    //please rotate your device 
}
