Getting error in - (BOOL)copyItemAtURL:(NSURL )srcURL toURL:(NSURL )dstURL error:(NSError **)error

Question

我正在从 iCloud 和 google 驱动器等中选取文档并使用此方法 - (void)documentPicker:(UIDocumentPickerViewController *)controller didPickDocumentAtURL:(NSURL *)url

我得到 url file:///private/var/mobile/Containers/Data/Application/34C6FC23-C8BF-407E-AD67-77758BD606E9/tmp/com.company.theApp-Inbox/chart%20(1).pdf

但是当我这样做的时候[[NSFileManager defaultManager]copyItemAtURL:url toURL:docUrl error:&error];

我遇到了这个错误 Error Domain=NSCocoaErrorDomain Code=262 "The file couldn’t be opened because the specified URL type isn’t supported." UserInfo={NSURL=/var/mobile/Containers/Data/Application/34C6FC23-C8BF-407E-AD67-77758BD606E9/Documents/documents/12345678901-1470638583.pdf}

这是我的 docUrl = /var/mobile/Containers/Data/Application/34C6FC23-C8BF-407E-AD67-77758BD606E9/Documents/documents/12345678901-1470638583.pdf

Answer 1

尝试使用以下方法初始化您的 docUrl：

NSURL *docUrl = [[NSURL alloc] initFileURLWithPath:@"/var/mobile/Containers/Data/Application/34C6FC23-C8BF-407E-AD67-77758BD606E9/Documents/documents/12345678901-1470638583.pdf"];

我猜 copyItemAtURL:toURL:error: 无法将您的 URL 识别为文件 URL。

Answer 2

请尝试初始化您的 docUrl：

NSURL *docUrl = [[NSURL alloc] initFileURLWithPath:@"file:///var/mobile/Containers/Data/Application/34C6FC23-C8BF-407E-AD67-77758BD606E9/Documents/documents/12345678901-1470638583.pdf"]

Answer 3

在swift世界中：

URL(fileURLWithPath: "/var/mobile/Containers/Data/Application/34C6FC23-C8BF-407E-AD67-77758BD606E9/Documents/documents/12345678901-1470638583.pdf")
