我有一个 Drag/DropNSView它应该接受我plist在 key下列出的相同文件类型和扩展名CFBundleDocumentTypes。该应用程序接受任何类型的视频文件、文件夹和不被该public.movie类型选择的多个文件扩展名。

（相当长的）列表CFBundleDocumentTypes是：

    </dict>
</array>

我已经能够在我的 NSView 的draggingEntered方法中验证 drop 接受，但我希望能够运行Info.plist条目CFBundleDocumentTypes而不是复制此方法中的所有条目。CFBundleDocumentTypes我怎样才能做到这一点，以便我的视图接受与条目中列出的完全相同的文件？

只需向您的捆绑包询问信息：

NSArray* documentTypes = [[[NSBundle mainBundle] infoDictionary]
                                    objectForKey:@"CFBundleDocumentTypes"];

This will return an array of dictionaries, one for each of the file types, from which you can easily extract the other information:

for(NSDictionary* docInfo in documentTypes)
{
    NSArray* fileExtensions = [docInfo objectForKey:@"CFBundleTypeExtensions"];
    //do something with this info
}

You could use this in conjunction with the -documentClassForType: method of NSDocumentController. This takes the value from the CFBundleTypeName Info.plist key as the type.
