Sarah, Thanks, I knew you were also learning the Obj-c stuff.
I wanted to do either show recent x number of images and or searchable
images (top twenty) and update a page on new images or coming to the
page. There may be thousands. I also want to write an iPhone viewer
app to view these images. So an image captured on the device and
manipulated in my app is then sent online. Online, (preferably iRev)
will process the file and display the file and push the needed iPhone
push code to the viewer app. Then I would want to provide some of the
social aspects like voting/rating and sharing and linking etc. Down
the road I would like to provide user password protected areas for
manipulating a users uploaded files, etc.
I am also planning an app that would allow users to add photos and
text to a page on the web for an individual user that would then be
downloaded to another of my iPhone apps as an update. After being
notified the user launches the app and it would check online for new
data and download that and process it for the user. I can explain this
one further but for now I just want to grasp the whole process for the
app I already wrote and what iRev can do for it.
Then lastly the easiest part would be to have a desktop app like in
your demo to display the images as well. I walked through your
tutorial and built the sample app.
I might be able to trigger an iRev script - that would be cool and
would help keep this in the realm I understand. Maybe that would be
the missing piece for me.
P.S. I uploaded the PHP script I borrowed in another reply.

Overview:
I have been plugging away at writing an iPhone application that
manipulates
photos and uploads them online (why I have been so silent on the
list for
awhile). And except for a major confusion working with the internal
database
(still unresolved) I have been able to get everything else working.
What I can do so far is load a view on the iPhone and take a
picture or use
a picture from the camera/library on the iPhone, add a background,
a frame
and some text from a database. I can also edit the text in a table
and save
to a user file in the device. Lastly, I can email and SMS the final
image to
another phone or computer and NOW I can send the picture up to rev-
online
via a 'borrowed' PHP script.
Great work. I too have spent some months struggling with Objective-C.
It's not bad as C goes - at least the IDE is nice to use - but it
seems to take ages to do things which are so easy in Rev...
What I would like to do is have either iRev or a revWeb standalone
'know'
when new images are uploaded and display them in the browser for
users to
see and show.
Not quite sure what you have in mind here, but it doesn't sound too
difficult.
Did you want a web page that only shows the recent images?
Or a web page that shows the last x images, but updates itself if
there are new ones?
Showing the most recent images is easy enough - you can use standard
Rev commands to list the long files in the images folder and sort by
date to get the new ones.
A web page can be set to refresh periodically by including a REFRESH
meta tag, but this is probably not what you want.
I have a slideshow page that uses AJAX to ask an iRev file for the
html to display next. The iRev file lists the images, picks one
randomly, works out the size so it can construct a valid HTML img tag,
then sends that tag back to the AJAX call. This uses JavaScript to set
the innerHTML of a div tag to show the new image. There is a
JavaScript timer so this happens every 5 seconds.
It sounds worse than it is, but you can see it in action here:
<http://www.troz.net/onrev/samples/slideshow.irev>
What you could do is have an iRev file that just returned true or
false depending on whether there were any new images.
If it returned false, the web page could just set up a new timer and
wait.
if it returned true, the web page could ask another iRev file for the
details of the images to display and then display them.
I would also like to have iRev/revWeb send out a push
notification to another iPhone application (the image viewer) so that
viewers will know that other users have uploaded new pictures. I am
studying
up on the push notification on the iPhone side.
Sorry, I haven't done any investigations of the push mechanism yet.
But if your uploading script can trigger an iRev script, I'm sure it
can do whatever is needed to push data.
I would not worry about PHP if I were you. iRev is a good replacement
for server-side scripting which is what PHP does.
You will need some JavaScript if you need any client-side scripting
i.e. timers, reactions to clicks on the web page, AJAX etc.
Please send more detail on what you really need and I'm sure we can
start to work out some scripts.
Cheers,
Sarah
