UIImagePickerController中的前置摄像头 [英] Front facing camera in UIImagePickerController

问题描述

我正在使用 UIImagePickerController 在iPad2中开发前置摄像头应用程序。

I am developing the front facing camera app in iPad2 by using the UIImagePickerController.

当我捕捉到图像显示为从左向右翻转。

When I capture the image it's shows as flipped from left to right.

如何更正？

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, 0, anImageView.image.size.width, anImageView.image.size.height);
        imgPkr.cameraOverlayView = anImageView;
        [theApp.TabViewControllerObject presentModalViewController:imgPkr animated:YES];
        [imgPkr release];
    }

推荐答案

您可以翻转图像源图像使用此

You can flip the image from the source image use this

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

编辑已添加swift代码

Added swift code

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