// 생성 후 할당

AVCaptureVideoPreviewLayer *captureVideoPreviewLayer = [[AVCaptureVideoPreviewLayer alloc] initWithSession:[captureManager session]];

// 세션 시작

[[captureManager session] startRunning];

[self setCaptureVideoPreviewLayer:captureVideoPreviewLayer];

// 뷰 할당

UIView *view = [self videoPreviewView];

[[self videoPreviewView] setDelegate:self];

// 뷰에 프리뷰 설정

CALayer *viewLayer = [view layer];

[viewLayer setMasksToBounds:YES];

CGRect bounds = [view bounds];

[captureVideoPreviewLayer setFrame:bounds];

// 방향성 지원하면 항상 위로

if ([captureVideoPreviewLayer isOrientationSupported]) {

  [captureVideoPreviewLayer setOrientation:AVCaptureVideoOrientationPortrait];

}
