I just found out that an iPhone can act as a web server to access the app's data. I'm using Xcode. How do I extend my app's capabilities so that users can edit app data using a Mac. Where can I learn about this? Can you give me summary and a website please?
I hope it's using Apache Tomcat. I suppose I have to build a website to process and display the app's data. I wonder if iPhone supports jsp since it's using UNIX. I really don't want to use PHP.
Currently Money Manager has that feature.
Searching for embedded iOS web server returns a few solutions:
Run a webserver on an iOS device
A small, lightweight, embeddable HTTP server for Mac OS X or iOS applications
Lightweight GCD based HTTP server for OS X & iOS
You will be unlikely to fit php or tomcat onto an iOS device; the lack of memory and processing power will be technically challenging.
Apple will also likely take a negative view of the inclusion of a general purpose scripting language in any app your submit to the App Store.
I have an application to develop but the problem is that is must download part of behavior as a list of instructions from a server.
Ideally it will download scripting code and execute it. The question is if there are any libraries to make it? For example, I have python script and I want to to execute it on device...
Any options?
thank you
Lua is very popular for games. You can embed Python, too. Apple won't enforce the "Objective-C only" clause unless you make it obvious that you use Python to script behavior. Do you think all the games on the store are scripted in Objective-C? No way. Just don't make your transgressions obvious and you'll be fine.
For security reasons, the app store does not allow apps containing programming languages capable of executing arbitrary code on the phone, so your app's market would be limited to users willing to jailbreak their phones to circumvent this restriction.
You could, depending on what you want to do, look at using the browser's JavaScript.
I need to create an iPhone application using Facebook.
The facebook FBConnect API supports FQL which is similar to SQL Queries.
I would be able to create the application easily using PHP as compared to Objective-C.
So if there is any way to create an iPhone application using PHP please reply to me.
Thanks.
Well, if you are developing something for jailbroken devices , yes it is possible to use PHP (you have to install it first from Cydia).Also note that you should implement a SQLite database if your app/script needs database functionality (you can't run a MySQL server natively on iPhone ATM).
But, as pekka mentioned, this is a really bad idea, because you must set up first a lighttpd web server on iPhone (not really comfortable), or if you're planing to implement a CLI PHP script, you should first launch it (using some C functions like pipe(), dup2(), fork(), execl()) and then parse its output inside your -not-so-Objective-C- iPhone app.
So think it again...
Does iPhone support XML-RPC, Is their any open source framework which I can use?
Checkout the source for the wordpress app. They might be using XML-RPC. :)
http://iphone.wordpress.org/
"Airsource Ltd" is really really incredibly wrong about that document. That document is specific to Mac OS X and NOT the iPhone. In fact (almost) all Apple iPhone documentation is hidden away behind a login page and a licence agreement. Most of the technologies that document refer to (e.g. AppleScript) do not even exist on the iPhone.
Amit, you'll have Zero luck if you follow Airsource's advice. You will however do ok if you do as "Lounges" says and go grab the wordpress source code. It looks like they rolled their own XMLRPC library for use on the iPhone.
As for SOAP - you're on your own. You might be able to find an opensource SOAP library built on top of libxml2 though. Good luck.
Yes iPhone support XML-RPC and wordpress opensource application is best example of it,
but from performance aspect I must say JSON is better to use with iPhone application,
from here https://github.com/stig/json-framework/ u can download JSON parser.
Hi I'm looking into iPhone development, and Objective-C is not be my preferred language. As far as I can see at this moment Ruby cannot be used to talk to Cocoa Touch at the moment on the iPhone.
So my question is, am I wrong? Can I use Ruby on the iPhone to develop Cocoa Touch applications. And what is the future looking like for Ruby on the iPhone?
Now you can with RubyMotion
In the iPhone OS, mprotect() will fail if you try to use it to mark writable sections of memory as executable. This breaks bridges like RubyCocoa (and probably MacRuby) that use libffi to create Objective-C method handlers at runtime. I believe that this is by design because it was not always the case.
Ultimately, this is more a matter of platform politics than technology, but a technical workaround for this exists. Instead of generating custom method handlers at runtime, precompile a pool of reconfigurable ones that are assigned as needed, essentially making the bridging process entirely data-driven. As far as I know, this is not yet being done in RubyCocoa or MacRuby.
Another significant thing to consider is that the compiled Ruby and RubyCocoa runtimes can be significantly larger than compiled Objective-C apps. If these libraries were available on the iPhone, this wouldn't be an issue, but for now, even if you had RubyCocoa working, you might not want to use it for apps that you distribute.
No, you are correct. Currently, and most likely for the foreseeable future, Ruby will not be an option, at least for AppStore applications. There's no reason you couldn't do this on a Jailbroken phone, but Apple is pretty wed to Objective C for official development.
You are better off as a programmer knowing a number of different languages - think of Objective-C as a good learning opportunity.
I've found that things you learn in other languages often make you a better programmer overall, and give you new insights into other languages you already know.
rhomobile is an option to run ruby code on the iPhone, but it's essentially web app development. A web server runs locally on the iPhone and your ruby code renders to standard client side web technologies (html/css/javascript).

Actually, the ruby cocoa bridge isn't awkward at all; things work remarkably smoothly, right down to connecting outlets in IB etc. The resulting code is down right beautiful.
As for iPhone development, if you want an official AppStore application, you're out of luck unfortunately. Apple dictated that iPhone is Obj-C/Cocoa Touch, and there's a clause in the SDK license saying that one of the things they will reject an app for is having a language interpreter/JIT compiler, so you couldn't add a ruby interpreter in your app yourself.
Off topic, but hilariously, this is why Flash for the iPhone is Adobe blowing smoke. They couldn't get a swf player onto the AppStore even if they wanted to, per Apple's license.
Uh, Rhodes (Rhomobile) does allow you to do native apps on the iPhone and all other smartphones. Yes, we do leverage doing rendering via the WebUIView control. But we allow all device capabilities and synchronized local data.
You might want to take a look at shinycocos. It is a child project of cocos2d-iphone, an Objective-C game programming framework for iPhone.
I haven't yet played with it, but from the git README I infer that it bundles Ruby 1.9.1 into your app.
I installed the ruby package from Cydia on my iPod Touch 1G jailbroken on 3.1.3:
Seems to work.
Now as for cocoa-touch that is a whole different story I would assume.
Take a look at http://www.appcelerator.com/products/titanium-mobile/
"Native iPhone and Android apps built with Web technologies."
Sounds good isn't it ? ;-)
No you can not create iOS native app in Ruby.
There is only two options for native apps for mac and iOS:-
Objective C and Swift Programming Language
Tutorials:-
Apple's official tutorial on Objective C
Apple's official tutorial on Swift Programing Language
If you are familiar with Ruby and only want to create iOS apps by Ruby. Ruby Motion, can be a cross-platform option for you, but it is not free.
Cross-Platforms
RubyMotion
Xamarin required .net skills
appcelerator HTML,XML,CSS,JS skills required
phonegap HTML,XML,CSS,JS skills required
I imagine it won't work right now, but I'd imagine that you'll eventually be able to use MacRuby to build iphone apps. Apple are putting a lot of work into it
Here's a link to an ADC article describing how to build normal cocoa apps
You don't have to use Objective-C to write iPhone apps. If you use QuickConnectiPhone, http://sourceforge.net/projects/quickconnect/, you can write it completely in JavaScript, CSS, and HTML and still have an installable application not a web app.
If you know ruby you are probably working with JavaScript already.
To see how to install it, run it, and other ideas go to tetontech.wordpress.com
There's an open-source Ruby-Cocoa bridge you might try to get working. But I gather that there's a bit of an impedance mismatch between Ruby and ObjC that makes it a bit awkward to use.
The Ruby Cocoa bridge probably will not work. Most of the bridges for dynamic languages need to generate executable thunks (either manually or with libffi). More limited bridges (for more static languages) may not have such issues.
In either event, bringing up a bridge is probably going to require becoming more familiar with the Objective C runtime than one would just learning how to write Cocoa Touch apps, which probably defeats the point of doing it in the first place.
Currently isnt true, Apple change their policies, take a look at ShinyCocos, is a ruby bindings for the Cocos2D-iphone game framework.

One possible solution would be to create an application wrapping for example the rice library (google it) which includes a ruby-vm. I reckon you would be able to create c++ wrappers that you could expose to ruby, thus making an environment for iphone development with ruby. This probably requires a lot of work though ^^
