Actually, I am converting it to NSData, and then adding it, and it
still returns nil

Read the docs _very_ carefully for this one. (And file a complaint
at the bottom of the doc’s page)
dictionaryFromTXTRecordData:
Return Value
A dictionary representing txtData. The dictionary’s keys are
NSStringobjects using UTF8 encoding. !!!!The _values_ associated
with all the dictionary’s keys _are NSData_ objects that encapsulate
strings or data!!!!
If you feed your NSDictionary anything else than NSData it will
return nil.
So you just have to convert your image to NSData and store that.

Hello,
Recently, I've been working on an app that will sync with an iphone
app. So, I am using NSNetServices. I would like the iPhone to
display the mac's icon, so I was thinking of using the TXT Record
to store the icon. However, whenever I add it to the dictionary,
convert the dictionary to data (using the NSNetService methd), it
becomes nil. I am guessing that's because it's too large. Then, I
decided to set the size of the image to (1,1) thinking it must be
small enough. However, I still got nil. Is there a way to send an
NSImage (as NSData in the dictionary, PNG formatted using an
NSImageRep then converted to data) through a TXTRecord. And, if so,
is there a way for the image to be able to be displayed on the
iphone? I know an NSImage cannot be displayed on the iphone, which
is why I converted it to PNG data, hoping the iphone could read that.
Thanks!
Joe
