ios - Swift - 从 UIImagePickerController Camera 中选取时，UIImage 旋转了 90 度

Question

我正在使用 UIImagePickerController 从相机和库中选取图像。当我从图书馆获取图片时，图片正常。但是，当我从相机中获取图片时，它会向右旋转 90 度。我的应用程序只能在纵向模式下运行。这是我获取图像的代码

    @IBAction func camPhoto(sender: AnyObject) {

    let imagePicker = UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.Camera
    imagePicker.allowsEditing = false

    self.presentViewController(imagePicker, animated: true, completion: nil)

}

@IBAction func importPhoto(sender: AnyObject) {

    let imagePicker = UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    imagePicker.allowsEditing = false

    self.presentViewController(imagePicker, animated: true, completion: nil)

}

我的函数 importPhoto 工作正常，但另一个没有。

    func imagePickerController(picker: UIImagePickerController,
    didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        let selectedPhoto = info[UIImagePickerControllerOriginalImage] as! UIImage

        img.image = selectedPhoto
        dismissViewControllerAnimated(true, completion: {

            self.convBtn.hidden = false

        })
}

有什么想法吗？

你可以试试:

func imagePickerController(picker: UIImagePickerController,
    didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        let selectedPhoto = info[UIImagePickerControllerOriginalImage] as! UIImage
        **selectedPhoto.withHorizontallyFlippedOrientation()**
        img.image = selectedPhoto
        dismissViewControllerAnimated(true, completion: {

            self.convBtn.hidden = false

        })
}
