iOS开发笔记-91:Swift5 - UIImagePicke

在使用系统图片选择器的时候，发现裁剪之后的图片有位置偏移
这个做一个小布丁

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
   let info = convertFromUIImagePickerControllerInfoKeyDictionary(info)
  var image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.originalImage)] as? UIImage
        var crop: CGRect = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.cropRect)] as? CGRect ?? CGRect.zero
        crop.origin.y = crop.origin.y + kNavigationBar64//kNavigationBar64就是偏移量
        image = ordinaryCrop(imageToCrop: image, cropRect: crop)
}
