swift - 尝试将图像保存到照片库时 iOS 10 应用程序崩溃

Question

我正在尝试将图像保存到 Swift 3 中的照片库(我正在使用 Xcode 8)。

View Controller 代码:

func shareImage(image: UIImage) {
    let items = [image]

    var activityVC: UIActivityViewController = UIActivityViewController(activityItems: items, applicationActivities: nil)
    let excludeActivities: [UIActivityType] = [UIActivityType.airDrop,
                                               UIActivityType.assignToContact,
                                               UIActivityType.addToReadingList,
                                               UIActivityType.copyToPasteboard]

    activityVC.excludedActivityTypes = excludeActivities

    self.present(activityVC, animated: true, completion: nil)
}

当我运行该应用程序并单击按钮截取屏幕截图(将其转换为图像，...，一切正常)时，该应用程序请求访问照片库的权限，我点击“确定"按钮，然后应用程序崩溃。图片未保存在照片库中。

我从 Xcode 得到的唯一线索如下:

};
} ... returned error Error Domain=NSCocoaErrorDomain Code=256 "The file couldn’t be opened." UserInfo={reason=Failed to access file: 1} with userInfo dictionary {

有人知道如何解决这个问题吗？

提前致谢!

更新

在社交媒体上分享图片效果很好，所以问题被指定为将图片保存在照片库中。
