如何在 Xcode swift 中更改图片方向

Question

我从照片库中获取一张照片并使用以下代码将其命名为图像：

@IBAction func importImage(_ sender: AnyObject) {
    let image = UIImagePickerController()
    image.delegate = self
    image.sourceType = UIImagePickerControllerSourceType.photoLibrary
    image.allowsEditing = false
    self.present(image, animated: true) { }
}

和这段代码：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        myImageView.image = image
        dismiss(animated: true, completion: nil)
        SubmitBtnOutlet.isHidden = false;
        Gurpcontroller.person = "yours";
        Gurpcontroller.collecterthing = "Coin";
        PictureViewController.imageuniversal = myImageView
    } else {
        //Error message
    }
}

我想看看图片是横向的还是纵向的。然后，如果是风景我想把它改成肖像。

您可以使用 image.imageOrientation 获取方向。

为了改变方向，最快的解决方案是从实际图像创建一个新的 UIImage，如下所示：

let newImage = UIImage(cgImage: image.cgImage!, scale: image.scale, orientation: .up)
