Question

我正试图让用户从自己的照片库中选择一张照片，并将其裁剪为特定尺寸，例如80 x 60的圆形照片。

@IBOutlet var imageView: UIImageView!

@IBAction func choosePhoto(_ sender: Any) {

    let imagePickerController = UIImagePickerController()

    imagePickerController.delegate = self
    imagePickerController.sourceType = UIImagePickerControllerSourceType.photoLibrary
    imagePickerController.allowsEditing = true
    self.present(imagePickerController, animated: true, completion: nil)
}

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let choosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    imageView.image = choosenImage
    dismiss(animated: true, completion: nil)
}

我使用此代码选择照片，但是编辑屏幕是一个矩形，所以它不是我想要的。是否可以更改编辑屏幕的尺寸？

默认情况下，iOS没有任何循环裁剪功能。您将需要集成外部库以实现裁剪功能。

您可以将其用于循环裁剪https://github.com/kekearif/KACircleCropViewController https://github.com/TimOliver/TOCropViewController

是否可以为UIImagePickerController的编辑器设置尺寸？
