objective-c – AVCaptureDevice isFlashModeSupported已弃用iOS 10

概述我正在使用AVCaptureDevice的实例方法“isFlashModeSupported”如下： NSArray *captureDeviceType = @[AVCaptureDeviceTypeBuiltInWideAngleCamera,AVCaptureDeviceTypeBuiltInMicrophone];AVCaptureDeviceDiscoverySession *capt 我正在使用AVCaptureDevice的实例方法“isFlashModeSupported”如下：

NSArray *captureDeviceType = @[AVCaptureDeviceTypeBuiltInWIDeAngleCamera,AVCaptureDeviceTypeBuiltInMicrophone];AVCaptureDevicediscoverySession *captureDevice = [AVCaptureDevicediscoverySession discoverySessionWithDeviceTypes:captureDeviceType mediaType:AVMediaTypeVIDeo position:AVCaptureDevicepositionUnspecifIEd];NSArray *deviceList = [captureDevice devices];AVCaptureDevice *selectedCamera = [deviceList objectAtIndex:(NSUInteger)currentCameraDeviceIndex];if ( [selectedCamera isFlashModeSupported:AVCaptureFlashModeauto] ){        [selectedCamera setFlashMode:AVCaptureFlashModeauto];   // AVCaptureFlashModeauto    }

但在iOS 10中,isFlashModeSupported和setFlashMode方法已被弃用.

Xcode建议使用AVCapturePhotoOutput的-supportedFlashModes.

有什么想法如何使用上述方法？

提前致谢

解决方法 使用此代码.这非常有效.

AVCaptureSession *session = [[AVCaptureSession alloc] init];[session setSessionPreset:AVCaptureSessionPresetPhoto];AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVIDeo];AVCaptureDeviceinput *deviceinput = [AVCaptureDeviceinput deviceinputWithDevice:device error:&error];if ([device hasFlash]) {   [device lockForConfiguration:nil];   device.flashMode = AVCaptureFlashModeauto;   [device unlockForConfiguration];}
