如何在 didFinishLaunchingWithOptions 中处理 unicode 文件路径

发布于 2024-11-18 21:50:15 字数 527 浏览 3 评论 0原文

我正在开发一个支持查看文档文件的应用程序。问题是我有一个名称为乌尔都语的文件。
当我从邮件应用程序中选择“在 MyApp 中打开”选项时，该文件将被复制到“收件箱”文件夹中。我想将此文件复制到其他文件夹。我从 launchOption 字典获取文件路径并将其传递给 copyItemAt 方法。获取文件路径的代码是

NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];
NSString *urlStr = [url absoluteString];

复制文件的代码是

[[NSFileManager defaultManager] copyItemAtPath:urlStr toPath:destPath error:&error]

但它返回错误“没有这样的文件或目录”。我已经检查过，该文件已正确放置在收件箱文件夹中，其名称为乌尔都语。

请帮忙。此致

I am developing an app which supports viewing of document files. Problem is that I have a file whose name is in Urdu language.
When I select "Open in MyApp" option from Mail app, the file is copied into Inbox folder. I want to copy this file to some other folder. I get the file path from launchOption dictionary and pass it to copyItemAt method. Code for getting file path is

NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];
NSString *urlStr = [url absoluteString];

And code for copying the file is

[[NSFileManager defaultManager] copyItemAtPath:urlStr toPath:destPath error:&error]

But it returns the error "No such file or directory." I have checked and the file is placed correctly in the Inbox folder with its name in Urdu language.

Kindly help.
Best Regards

通常，路径的格式为 /../.../filename.extension，文件 URL 的格式为 file://../.../filename.extension< /代码>。当您使用 absoluteString 时，您将获得与字符串相同的 file://../.../filename.extension 。您应该改为向 path 发送消息。

NSString *urlStr = [url path];

Usually, paths are of the form /../.../filename.extension and file URLs are of the form file://../.../filename.extension. When you use absoluteString, you will get the same file://../.../filename.extension as a string. You should message it path instead.
