Answer 1

.zip    application/zip, application/octet-stream

Is this supposed to be a single value or a choice of several? – Blacksnake

This won't guarantee you a zip file at all. According to the WC3 specifications this will be intrepreted as: "I prefer a application/zip content type, but if you cannot deliver this an application/octet-stream (file stream) is also fine". – Gravamen

Also seen application/x-zip-compressed – Araliaceous

application/x-zip-compressed sound like some custom header for specific system. application/zip, application/octet-stream are common. – Solo

Answer 2

The standard MIME type for ZIP files is application/zip. The types for the files inside the ZIP does not matter for the MIME type.

As always, it ultimately depends on your server setup.

Answer 4

If you want the MIME type for a file, you can use the following code:

- (NSString *)mimeTypeForPath:(NSString *)path
{
    // get a mime type for an extension using MobileCoreServices.framework

    CFStringRef extension = (__bridge CFStringRef)[path pathExtension];
    CFStringRef UTI = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, extension, NULL);
    assert(UTI != NULL);

    NSString *mimetype = CFBridgingRelease(UTTypeCopyPreferredTagWithClass(UTI, kUTTagClassMIMEType));
    assert(mimetype != NULL);

    CFRelease(UTI);

    return mimetype;
}

In the case of a ZIP file, this will return application/zip.
