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];
}
