Try to use AVCaptureDevice:

    Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");

    if (captureDeviceClass != nil) {
        AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

        [device lockForConfiguration:nil];

        if ([device hasTorch]) {
          if (device.torchMode ==  AVCaptureTorchModeAuto) {
            NSLog(@"Auto");
          }
          if (device.torchMode ==  AVCaptureTorchModeOn) {
            NSLog(@"On");
          }
          if (device.torchMode ==  AVCaptureTorchModeOff) {
            NSLog(@"Of");
          }
        }

        if ([device hasFlash]) {
          if (device.flashMode ==  AVCaptureFlashModeAuto) {
            NSLog(@"Auto");
          }
          if (device.flashMode ==  AVCaptureFlashModeOn) {
            NSLog(@"On");
          }
          if (device.flashMode ==  AVCaptureFlashModeOff) {
            NSLog(@"Of");
          }
        }
        [device unlockForConfiguration];
    }
