UIImagePickerController中的前置摄像头

问题描述

您可以使用源图像翻转图像

UIImage *flippedImage = [UIImage imageWithCGImage:picture.CGImage scale:picture.scale orientation:UIImageOrientationLeftMirrored];

添加了快速代码

let flippedImage = UIImage(CGImage: picture.CGImage, scale: picture.scale, orientation:.LeftMirrored)

解决方法

我正在使用来开发iPad2中的前置摄像头应用程序UIImagePickerController。

当我捕获图像时，它显示为从左向右翻转。

我该如何纠正？

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) 
    {
        UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
        imgPkr.delegate = self;
        imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;
        imgPkr.cameraDevice=UIImagePickerControllerCameraDeviceFront;


        UIImageView *anImageView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"select%d.png",val]]];
        anImageView.frame = CGRectMake(0,anImageView.image.size.width,anImageView.image.size.height);
        imgPkr.cameraOverlayView = anImageView;
        [theApp.TabViewControllerObject presentModalViewController:imgPkr animated:YES];
        [imgPkr release];
    }
