I'd like to use Scripting Bridge to find messages in Mail's Inbox that
have attachments with a certain suffix (e.g., txt) and ultimately
retrieve just those.
When I get a reference to "Inbox", what I want (in plain English) is ALL
messages that have at least one attachment whose name ends in "txt".
I took the SBSendEMail example code as a base, and was hoping I could
get the last code chunk at the end to work, but it fails.
MailApplication *mail = [SBApplication
applicationWithBundleIdentifier:@"com.apple.Mail"];
MailMailbox *inbox = mail.inbox;
SBElementArray *messages = inbox.messages;
#if 1 // cannonical routine, works fine, slow
for(MailMessage *message in messages)
{
SBElementArray *mailAttachments = [message mailAttachments];
for(MailMailAttachment *attachment in mailAttachments)
{
if([[attachment.name pathExtension] isEqualToString:@"txt"])
{
; // NSLog()
}
}
}
#elif 0 // works, takes a REALLY long time
SBElementArray *atts = [messages
valueForKeyPath:@"@unionOfArrays.mailAttachments"]; // time hog
NSPredicate *filter = [NSPredicate predicateWithFormat:@"SELF.name
ENDSWITH 'txt'"];
[atts filterUsingPredicate:filter];
#elif 0// fails
// Prefilter, getting only those Messages that have attachments first...
NSPredicate *filter = [NSPredicate
predicateWithFormat:@"self.mailattachmen...@count > 0"];
[messages filterUsingPredicate:filter];
#endif
Am I missing something, or is this just the best that I can do?
David
