从iCloud文件选择器附加iWork文档不工作，因为它们是目录而不是文件 [英] Attaching iWork documents from iCloud Document Picker does not work because they are directories not files

问题描述

转换任何iWork文档（页， Keynote ，数字 c）到中的 NSData 似乎不起作用，因为它们不是文件而是目录。

Converting any iWork documents (Pages, Keynote, Numbers) into NSData from the UIDocumentPickerViewController does not seem to be working since they are not files but directories.

这是我的代码：

NSString *fileName = [[url path] lastPathComponent];
NSData *fileData = [[NSFileManager defaultManager] contentsAtPath:[docPickerUrl path]];
NSString *fileExtension = [docPickerUrl pathExtension];
NSString *UTI = (__bridge_transfer NSString *)UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, (__bridge CFStringRef)fileExtension, NULL);
NSString *contentType = (__bridge_transfer NSString *)UTTypeCopyPreferredTagWithClass((__bridge CFStringRef)UTI, kUTTagClassMIMEType);

fileData总是 nil $ c> NSFileManager 无法将目录转换为数据。

fileData is always nil since NSFileManager can't convert directory to data.

我得到 url 从 - （void）documentPicker：（UIDocumentPickerViewController *）controller didPickDocumentAtURL：（NSURL *）url

推荐答案

我有同样的问题： iOS8：UIDocumentPickerViewController get NSData

解决方案是将iWork文档添加为zip存档，最简单的方法是使用 SSZipArchive 库也可作为可可豆：

The solution is to add iWork documents as zip archives, the simplest way is to use SSZipArchive library, also available as cocoa pod:

pod 'SSZipArchive', '~> 0.3'
