Hi list Given an NSData object, with no context as to what it might be, is it possible to find if it contains a document of recognised file type?
I know this is possible for image files, by using the imageIO framework and doing the following: CGImageSourceRef imageSource = CGImageSourceCreateWithData(myNSDataObjectGoesHere, NULL); NSString *uti = (NSString *)CGImageSourceGetType(imageSource); NSString *extension = [[NSWorkspace sharedWorkspace] preferredFilenameExtensionForType:uti]; CFRelease(imageSource); // Standard typed-in-mail-disclaimer here I suppose I could take the long route of writing the data to disk, then using the NSWorkspace method -typeOfFile:error:, but that seems a bit heavy-handed. Can anyone suggest a better way of doing this? I've been unable to find anything in the archives or Google, but perhaps I'm using the wrong search terms. - Ben _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
