ios - AVCaptureDevice Low Light Boost swift

有人知道如何为您的 ios 相机应用设置低光增强功能吗？这是我拥有但无法使其工作的代码。

let backCamera = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo)
    do {
                try backCamera?.lockForConfiguration()
                if (backCamera?.isLowLightBoostSupported == true) {
                   backCamera?.automaticallyEnablesLowLightBoostWhenAvailable = true
                }
                 backCamera?.unlockForConfiguration()
                 }
                 catch{
                     print(error)
                 }

你不需要那个。把它放在 didMoveToView 中:

captureSession!.sessionPreset = AVCaptureSessionPresetPhoto
