Well, I got the “public.url” and “public.url-name” UTIs from Apple
Development’s UTI guides. But before reading this post, I’ve been thinking
about other line of attack.
I said that my “Open URL” doesn’t register, but Safari’s does. So I want to
see Safari’s NSServices information to see what it does. To my shock, it’s
not there! I have no idea where the “Open URL” service that triggers Safari

command. I was about to give up when I remembered that the Services menu
shows Safari’s “Add to Reading List” command, and I did see that in Safari’s
Info.plist.
When I read the NSServices entry for “Add to Reading List,” I found out that
Safari cheats! The service only takes RTF and UTF-8 text, put there’s a
required-context block that filters in only URL strings and http(s) strings.
(The latter filter is enabled by an Apple-private(?) key called
“NSLinkSchemes.”)
…
I did a web-search on “NSLinkSchemes,” and found a text dump of all of
someone’s services, and the “Open URL” service was listed as being from a
“/System/Library/CoreServices/SystemUIServer.app.” Sure enough, my copy of
that app has the service, and lists “NSURLPboardType” and
“NSStringPboardType” as its send-types (in that order). Maybe I should follow
the lead of one of these services.
(The “/Applications/Font Book.app” was the only other app in the dump that
took “NSURLPboardType,” and it was for both of its two services, and the
fourth out of five types for both services.)
…
Now my web-searching has found a private Pasteboard type
“WebURLsWithTitlesPboardType” that could be what Safari used to create URL
Title entries.
Here’s what I got:
keyNSServices/key
array
dict
keyNSMenuItem/key
dict
keydefault/key
stringOpen URL/string
/dict
keyNSMessage/key
stringopenURL/string
keyNSPortName/key

keyNSSendTypes/key
array
stringpublic.url/string
stringpublic.url-name/string
stringpublic.rtf/string
stringpublic.utf8-plain-text/string
/array
/dict
/array
The entry field for a service’s sendable types, in the project attributes edit
section, is ambiguous whether it means NSSendFileTypes or NSSendTypes. I had to
put an empty NSSendFileTypes to ensure what I wanted. My implementation is:
- (void)openURL:(NSPasteboard *)pboard userData:(NSString *)userData
error:(NSString *__autoreleasing *)error {
NSUInteger counter = 0;
for (NSPasteboardItem *item in pboard.pasteboardItems) {
NSURL * const targetURL = [NSURL URLWithString:[item
stringForType:[item availableTypeFromArray:@[(__bridge NSString *)kUTTypeURL,
(__bridge NSString *)kUTTypeRTF, (__bridge NSString
*)kUTTypeUTF8PlainText;
++counter;
if (targetURL) {
id const browser = [[NSApp delegate] createBrowser];
if (browser) {
[browser showWindow:NSApp];
[browser loadPage:targetURL title:[item
stringForType:@public.url-name] searching:nil printing:nil showPrint:NO
showProgress:NO];
} else if (error) {
*error = [NSString stringWithFormat:@A browser window could
not be created for item #%lu (of %lu)

I’m stumped. I’ve been looking for Apple sample code, but since it likes

at one time add an -init and -dealloc with logging just to make sure the

that the service provider was being retained and not instant-deallocated.

I always do full phrase searches on error messges for best results. See
