I was checking out an iphone game called kijja where they have a live connection from the app to a website and you use the phone as your game controller. Does anyone know what they are using to do this on the backend? http://kijjaa.com/air/
It got me thinking of some ideas and I was wondering if you might be able to do the same thing from a web app in mobile safari instead of a native app, maybe using node.js? Does that seem possible or am I dreaming?

We are developing a Single Page RWD web app which supports all mobile form factors. We would like to
have the webapp support offline browsing capability as well
Once the data is downloaded from server, user should be able to see that data even if there is no internet connection.
Users should be able to fill forms, and later submit it to server, when there is internet connection.
Can we use the AppCache, HTML5 storage to get the offline capabilities? If we are using hash to change the navigation in address bar the whole page refresh problem is also not there.
Was going through some of the older posts in Stackoverflow on this. Offline iOS web app: loads my manifest, but doesn't work offline

If you want to open something from an URL to the webView, you need internet. You can do the following thing in the iOS application with certain conditions.
Users should be able to fill forms, and later submit it to the server, when there is an internet connection.
You need to cache all the responses when using the native iOS or any other cross platform. If you are wondering about PWA, it is coming in the 11.3 version of iOS. Refer this link to understand more about the service workers in the WebKit. It is a beta version, so do not expect it to run bug free.
I need to create an iOS app that just displays a website. The site allows users to record audio. The purpose is to let mobile Safari users to record audio (which is currently not supported). Are there any decent solutions for this or am I going to have to hack my way through? So far I have the following two ideas:
1) Build a native application that contains a WKWebView of the site. If the website detects mobile Safari it will launch some JavaScript that the app can respond to (or it will try to bring the user to the App Store using Universal Links). The native app will then record the audio and send it back to the website somehow (either through an external server, or perhaps through JavaScript, not sure how much data can be passed, but it could be up to 1MB).
2) Use an existing solution using perhaps Cordova/PhoneGap.
Hope to get some tips!
Build an hybrid application based on cordova/PhoneGap seems to be the best in my opinion. In addition you can build for iOS and Android (if you need later).
You can easily use this plugin to achieve your app.
I'm developing an app for a client and am experiencing an issue where the app is still using mobile data on my device, even though I have mobile data turned OFF for the mobile app, and wi-fi is switched OFF also.
The app is a video-calling app, using WebRTC, Sockets (socket.io) and usual API calls. All of these are still being used and successfully returning data, meaning a fully-fledged video call is working, despite the wi-fi being disabled and mobile data being restricted too.
I'd obviously like to resolve this situation, as I fear the app could be rejected by Apple upon submission.
The same experience occurs regardless of whether the device is connected to USB or not.
Only Airplane mode seems to provide the correct 'no connectivity' experience.
I need to view some local (saved somewhere in the iPad) html / js contents with mobile Safari. By reading some threads it seems that the file:// protocol is disabled. Right?
If so, the solution I see is to install an app which turns the iPad into an http server (no need for support of php or anything else), load my contents there and access somehow them within the same device by http://localhost/... or http://127.0.0.1/... with mobile safari.
Is that actually possible? Can someone please suggest me a good web server app which possibly does not require jailbrake or other hacking?
Thanks!
You probably can't do what you want because in order for your application to be serving up HTTP requests to Mobile Safari, it would have to be running in the background, and there's no permissible background mode that covers this.
If you only need a one-time-only response immediately after running your application, then you could possibly use beginBackgroundTaskWithExpirationHandler:, although this might not be approved by Apple - it's difficult to predict their response to that.
If you are sure that you don't need this to go into the App Store, then you can get your application running in the background permanently by abusing one of the other background modes, such as pretending to be a VOIP app or media player.
Once you're running in the background, you can use CocoaHTTPServer to actually serve the files.
If you describe what you are trying to achieve, somebody might be able to suggest an alternative approach to using local files / Mobile Safari.
I don't think this is currently possible with straight HTML (although I've heard that HTML5 may support this in the future):
I'd like a web app that can record audio from the iPad (and also, ideally iPhone).
This will not be an iOS app. It's a web page.
Unfortunately, no. The only hardware functions you can get access to via HTML/JS are the location service and the accelerometer.
