AVCaptureDevice低光提升迅速

Question

有谁知道如何为你的ios相机应用设置低光增强？这是我的代码，但无法使其工作。

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

Answer 1

你不需要那个。把它放在didMoveToView：

中

captureSession!.sessionPreset = AVCaptureSessionPresetPhoto
