Question

When using the front camera of the iPhone 4 to take a picture, the taken picture is mirrored compared with what you see on the iPhone screen. How may I restore the \"on scre

Answer 1

I'd like to vote up @Lucas Eduardo , I have tried to integrate the component LEImagePickerController into my project as below:

- (void)onCamera:(id)sender {
    UIImagePickerController* imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
    imagePicker.delegate = self;

    //cover the switch button at the top right corner, I just need user take photo with the front facing camera
    UIView* view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
    view.center = CGPointMake(CGRectGetWidth(imagePicker.view.bounds) - CGRectGetWidth(view.bounds)/2, CGRectGetHeight(view.bounds)/2);
    view.backgroundColor = [UIColor blackColor];
    [imagePicker.view addSubview:view];

    LEMirroredImagePicker* mirrorFrontPicker = [[LEMirroredImagePicker alloc] initWithImagePicker:imagePicker];
    [mirrorFrontPicker mirrorFrontCamera];

    [self presentViewController:imagePicker animated:YES completion:nil];
}

As the other answers, I had the same problem. But just flip the final image is only half the answer, because the preview image, displayed by the UIPickerController when you take a picture with the front camera, it's still inverted (mirrored).

Based in some codes from internet, I created a Pod to get this wanted behavior:

https://github.com/lucasecf/LEMirroredImagePicker

After installed, you just have to call this two lines of code together with your UIImagePickerController:

self.mirrorFrontPicker = [[LEMirroredImagePicker alloc] initWithImagePicker:pickerController];
[self.mirrorFrontPicker mirrorFrontCamera];

And thats it, simply as that. You can check for more informations in the README of the github link.
