I made an iPhone Webapp that allows an user to consult a distant database. At some point the user has to enter a code wich is quite long (about 17 digits). I would like to make the webapp remember the 3 or 5 last codes he typed.
How can I achieve this using the cache-manifest? (I have never used it but it looks like the right solution).
Thanks you for your attention.
In the end, I figured out that using cookies would be the easiest way to do it, and hopefully cookies are actually kept for Webapps. I will struggle with the cache-manifest on an other episode.

Facebook recently announced the introduction of messenger codes which can be used to add new contacts and, more importantly, communicate directly with businesses and business pages (which is why I'm interested in it).
It took me ages to find it but on the bottom left of the messages tab on my Facebook page I have the option to download my code in three different sizes - clicking the disc will open a modal window where you can click the Download button and choose from 300, 600 or 1000px PNG file downloads.
NOTE: While they are PNG files the background is not transparent which seems like a bit of an oversight to me but hey ho that's what Photoshop is for I guess.
The problem is that while I can download my code I can't find any way to test it on printed materials (or even electronically at the moment!). The scanning feature doesn't seem to have been rolled out for me yet (I tried re-installing the Messenger app to see if I got a newer version but that didn't work) and nor for anyone I know (I'm in the UK). The codes are bespoke to Messenger so can't be scanned or tested using any other app.
I'm probably too far ahead of the game but is there any way I can test to see if my code scans correctly, or anywhere I can go to find out? I would like to use it on some promotional material which is likely to be long term materials that I don't want to have to update in the near future (several years, by which time it's likely these codes will be more commonplace).
I also need to know what the redundancy is like. For example the high redundancy QR codes I generate can have up to 30% of the code covered while still being usable, which is great for design purposes. I can't find any official documentation as yet for these codes at all, let alone what is required, what the spec. is etc.
I know the most likely option is 'sit and wait' but I really would rather not if possible. I've never been very patient...
Thanks
UPDATE: My Messenger app has now been updated so I can test, but I'm leaving this here in case anyone knows of another way to test perhaps? If someone doesn't have Messenger on their phone for example.
I started looking into OwnCloud app development to add some capabilities I would like to my server. To me it seems like Apps can't modify anything like the Login page or User Management page. Is this the case?
I want to build a user registration app and would love to integrate it into the user management page (if not and it has to exist as its own app page not a big deal). The one big problem I see so far is not being able to add a "Register" link to the login page. I could just go in and add it to the source manually, but I would like to keep the App self contained so others can use it too.
If this is not possible to do in an App I may just need to modify the core application and then see if they will accept my feature addition in a pull request.
Thanks to anyone who can shed some light on this for me. I don't want to waste my time trying to figure out how to do it with an App on the platform if it wont be doable.
After a lot of digging around I did figure out a way to do this.
In the App's app.php file, you can force a script to be loaded if the plugin is enabled:
$api->addScript('script_name'); // without .js
In that script jQuery can be used to add the elements to the page where you need them.
This was a good solution for me since I only needed to add a single button to the login page. I can see this being a bad idea if you want to make vast modifications. At that point you might as well just create a separate page that you have full control over.
I've read a number of posts on Apple's forums, and a number of posts on the Cycling '74 forums (with my own questions scattered around both) and nobody seems to be able to help me.
I used Max/MSP to write a 'patch' that takes samples and generates music. I'm going to release it as an album similar to Brian Eno's Thursday Afternoon, but wanted to make it available to people so they can have the music last for more than the hour a CD can hold.
What I don't know how to do, and can't figure out is HOW. It looks just like a regular OS X app, and the only difference I see in the directory structure is that my Max/MSP made application has extra .framework folders as well as the objects I use (which I guess are similar to 'functions' in JScript). I've looked at the package contents of both OS X files and the unpacked .ipa files from the App Store. Being so similar I would imagine it'd be pretty easy.
Where do I start? Has anybody on this forum done this? Thanks for your time!
[edit] - I just wanted to let you know I've discovered RJDJ, an iOS app that allows users to create 'scenes' in Puredata (Pd) and load them on their RJDJ program. I'd rather not go this route.
[edit2] - ok. I agree that it's very different. Especially having 4 (i could cut it down to 3) additional frameworks that aren't part of the SDK. But Ive been thinking. I can add a JavaScript object inside of my program, or make a special new object (object in max is sort of like a class in JS, i think) using C. Is there anything in these languages that would be able to convert a simple 'touch' to a 'mouseclick' in my app?
My application is very very simple. Basically just samples, played at randomly generated time intervals with some a 'conductor' to bring in/out the groups the samples are drawn from (piano, fx, etc...). So the user just clicks the 'start' button and off it goes. So the .nib file I would need to create is very simple. In my head it seems like the .ipa package/ios .app both contain unix executables and so long as these are basically the same it should work, right?
Max6 has been released.
A new object/concept named gen~ is available.
As far as I discussed with C74 dev, I know gen~ WILL provide its source code output. This code produce by the gen~ object could be useable in any other framework. basically, it will be C++
So it would really open A LOT of possibilities ; Max becoming a real graphical framework producing output that can be used in programming world.
It would save time for some part of the code.
As far as I can see from poking around at the Cycling '74 site and forums, there's currently no Max engine available for iOS. libpd is probably your best bet, really. (I'd note that the Inception app uses this Pure Data engine with a custom interface and it works very well.)
Unfortunately OSX and iOS apps are completely different under the hood. Outwardly they look similar (eg. you've noted the .app extension) but the internals are completely different.
I want to be able to search an html page that is refreshing every 10 seconds for the word "stat". If the word is found I then want to alert the user through a pop up dialog and possibly a repeating sound until the user acknowledges it.
UPDATE:
Sorry the question was a bit ambiguous. I do not know a great deal about this stuff I just do it as a hobby.
OK so here is the deal. I work as Biomedical Electronics Technician for a hospital. We have a work order system that is web based. Nurses can enter a work order into this system. I have a browser window open at all times that refreshes periodically through an add-on for IE so I can always be up to date on the status of the work orders coming in. When a nurse the enters enters a work order they have the option of choosing Stat, High, Medium, or Low for the priority. When a stat work order is placed our response time should be within five minutes theoretically. I want some way to alert myself when a stat work order has been placed so I can respond accordingly. And I know a repeating sound would be annoying, but that might be the best way to get my attention.
Another caveat to this is the work order status can be changed by me, the tech. So when a work order is initially placed the status is Not assigned or something like that. Once I go start on a work order I change the status to In Progress. If I have to order a part I change the status to Hold for Parts, etc. So basically, what I am saying is I don't want to alerted if the status is anything but "Not assigned". If it will help I will get a copy of the source of the page when I get to work tomorrow.
Our IT department seems unwilling to help and the company that made the product is so busy chasing the daily bugs that show up to add new features such as this at this time. If I knew more a Google search might help, but alas I am a bit noobish in the programming realm, however I am 2 years from a C.S. degree so I am not a complete novice.
To answer another question, I do not have access to the page I am just viewing it so any sort of script would need to run on my client machine.
Thanks
I found this, try it https://addons.mozilla.org/en-US/firefox/addon/3028/
Maybe it can search for STAT on the entire page?
Based off your description, it doesn't sound like you have access to the server to change the code of the page itself, correct?
If that's the case, spend some time learning how to use Greasemonkey (or rather Greasemonkey for IE). It allows you to add functionality to a web page from the client (browser) side, regardless of what's on the server.
You'll need to find the elements that hold the "stat" term your after, and have it check periodically those elements periodically. Look into the setTimeout method for that periodicity. The rest you'll have to work out specific to that page.
What you're looking for, since you have python available, is to build a simple, easy to use webscraper.
First link is how i would do it quick and dirty.

Basically, read the page (even set the whole loop on a 10 second refresh timer).
Go line by line with a while readline loop.

We we wondering what are some ways developers have added a help function to their apps. What are some techniques people have used?
One way we were thinking of is to us UIWebView to display a HTML file with help instructions.
Thoughts appreciated.
I'm using UIWebView right now which pretty much contains all the help in a single page, along with some JQuery things to display popups, etc. But I like the way iCab Mobile (et al.) are doing things which is a sectioned UITableView with each row a separate topic or section within their overall help information (complete with icons...) then in their bundle they have each section in its own html file, organized by localization.
Another thing in my queue for the next release is to provide a dynamic "News" view. The rough idea is as follows... I have on my server a file or CGI where I can place small bits of news I'd like to push out to users. On startup, my app checks for network availability and if present, start a thread to see if anything has changed on the server since last updating the News data. If changes present, post an alert letting user know, and asking if they'd like to read it now. At that point, the latest news is already downloaded and cached, so they can simply read it later if they want, and I won't post anymore alerts until the server file changes again. (And one could add a preference/setting to disable these alerts.)
I'm thinking this would be a good way to let people know that some nasty bug is known and fixed and an update is sitting in the queue, solicit beta testers, promote upcoming features or other apps, etc. I can see where constant alerts everytime I've got something new to promote would get annoying, so having a setting to disable them means the user never has to read them unless they want to. Although some kind of override to warn of recently discovered/fixed bugs seems sensible.
FWIW, the author of Mover+/Mover has just started doing a similar thing, though I think Emanuele is perhaps only showing one Notelet at a time, whereas I envision a bit more of a history (shown in UIWebView) until I decide to age stuff off the bottom of the stack.
I'm using a scroll/page view to show several images containing small notes. Each image then tells the user about the more advanced functions on a specific part of the app.
In my opinion the help should only contain information that isn't a 100% relevant for the use of the application. It should be things the advanced user should use to make more use of the app. It should contain gold for the power users. The "basics" should be so obvious that no help would ever be needed. If that's not the case, I think, you've failed as a developer on the iPhone platform.
(Here's a screen shot from my demo app)
I'm currently creating a fairly complicated app. I'm thinking of doing help as a semi-transparent overlay - help in text form is hard to swallow for users; it's much more helpful to just point at stuff and say "this does that".
