ios - 拍摄照片并将其保存到相机胶卷

Question

我遇到了一个问题，我只想要一个简单的解决方案来拍照，然后将其保存在我的应用程序中。然而到目前为止，我所能做的就是拍摄照片并将其加载到 UIImageView 中，但它不会保存在相机胶卷中。

- (IBAction)takePhoto:(UIButton *)sender 
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;

    [self presentViewController:picker animated:YES completion:NULL];
}  

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.imageView.image = chosenImage;

    [picker dismissViewControllerAnimated:YES completion:NULL];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker 
{
    [picker dismissViewControllerAnimated:YES completion:NULL];
}

如有任何帮助，我们将不胜感激。相信我，我真的需要它。

你会想要这样做:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];

    self.imageView.image = chosenImage;

    UIImageWriteToSavedPhotosAlbum(chosenImage, nil, nil, nil);

    [picker dismissViewControllerAnimated:YES completion:NULL];
}
