app built with old GData static lib failing

[mr.riddlemefish]

Hi, I've not been paying attention to activity here since October last
year but I'm trying to trace the cause of a crash now happening with
an app built at that time. With a rebuild on the simulator and linking
with a static GData lib built at that time I'm noticing that I can
repeatably get this error message

2010-04-03 16:05:00.800 MyApp [14075:207]
serviceBase:<GDataServiceGoogleHealth: 0x4828010>
objectFetcher:<GDataHTTPFetcher: 0x3e35120> failedWithStatus:304 data:

in the log when working with the GData Health API. It may not be
related to what's happening on the iPhone device itself, but it's a
start.

Software versions etc have moved on since then and yes I know I should
get the latest version of the GData API and rebuild for modern times
but what am I up against with this, before I get into nitty gritty?

Thank you.

Status 304 is "Not Modified". It means the server isn't sending a response because the data has not changed since the previous time the same URL was requested by the application.

The Objective-C library's service class has an optional cache ([service setShouldCacheDatedData:YES]) which can store the server's responses so an application does not need to see the 304 status codes.

Ah, the server is smarter now. The iPad just wasn't reason enough for rebuilding but it looks like I have work to do now.

As always, thanks Greg.
