I am running a Websocket client using nodejs-mobile in my iOS app. The other part of my app is done in Objective C. I want to pass text messages received from the Websocket (nodejs-mobile layer) to the ObjC layer. I could not find a solution for it. Is it even possible and can someone provide a way to do this?
For example on JavaScript side something like:
callObjCfunction(myObjCfunction, textmessage);
On ObjC side something like:
- (void) myObjCfunction:(NSString*)textmessage {
[textfield setStringValue: textmessage];
}
Note: this is only an example. If there are other ways to communicate between these two layers I am interested in it.
EDIT: Found a solution which is surely not "best practice" and very limited but it works for me since I only want to pass text messages. I'm calling console.log() in JavaScript and redirect the stdout in native ObjC.

I've built a simple app/service that I'm displaying inside a UIWebView. Traditional links work just fine, but click events don't work at all. I'm aware this is a "thing" and I've looked at lots of code samples, and looked into touchstart etc., but nothing seems to make a dent in the problem.
Is there a definitive guide to making JS click events work inside web views, even if it involves passing messages to iOS?
Underlying app is Rails/Coffeescript. Current event code looks like this:
$('#frame ul li').on "click", ->
# Do stuff
Don't you use hosting jQuery on the Google server? The resource is likely to blocked by App Transport Security (ATS).
If so, the easy way is to set the domain to NSExceptionDomains.
I know that someone mean will probably close this question for being opinion, but the truth is, I'm not after opinion as such, but actual facts about the correct way and how to do this.
I've been searching around for quite a time and I'm still unclear as to what direction to take. It seems there are a billion* libraries that I could use, but I want to know what would be the correct, proper supported method of achieving this.
Essentially, I have a very simple requirement to list and download files from Sites on our Office 365 subscription to an iOS application.
Initially, I looked at the REST interface for Sharepoint and, from a browser, was able to easily perform a GET to our site and receive and receie a response with meta data about the file, for example:
https://mytenantid.sharepoint.com/_api/web/getfilebyserverrelativeurl('/MyFile/Here/Document.txt')
I could also retrieve JSON output instead of XML by specifying an Accept header of application/json using the POSTMAN REST client for Chrome.
So far, so easy. Just the authentication to do outside of the browser and that's it.
Phew!!
I started by looking at Basic authentication, but wasn't sure if this is the right way to do it and even if it would work?
On looking further, it seems that actually, using OAuth might be the way to go. Apparently, you can either do this yourself (no idea how), or use a library (ADAL?) from Microsoft? Unfortunately, this all looks half baked will very little documentation that seems to work. It also requires the use of CocoaPods and workspaces and isn't just a simple library that I can copy to my project and start using (a la SwiftyJSON). There also seems to be a lot of other libraries around too.
I should mention that I'm using Swift, so I've tried converting code from Objective C to Swift (unsuccessfully) too. Apparently I can't use "readWithCallback" with an argument list that the code tells me I should actually use -- even a sample application I downloaded had the same issue.
I've also tried using node.js with a script (not a Web Application) and the documentation and number of libraries available for that is almost worse.
Any assistance to achieve this really simple capability would be hugely appreciated -- it's been driving me nuts.
Many thanks,
D.
*this might be a slight exaggeration.
Office 365 has a RESTful API that you can use any programming language to authentication and integrate in your app.
Here is a simple example for iOS connected app to office 365. The sample shows how to do this in Objective C and SWIFT.

I have a script that takes hours and outputs if it is open or closed and I want to run this on my server, and then from my iOS app get if a certain place is open or closed. And I was wondering how I could do this without generating an JSON file and then parsing that as I would to frequently re-generate the file as the things change from open to closed and such. So is there a way I could make a call to the server and just get the data that I want?
Im not entirely sure whether you are asking specifically for an iOS framework for requests and responses or server side. So I figure I will try to answer both. Here are some swift projects you might be interested in. I'm not incredibly familiar with objective c yet but these resources might prove useful.
Alamofire
This will help you send and receive http requests.
Swifty JSON
This will help with JSON parsing
However if your question is more regarding server side issues. You could look into a REST api and that way you could only request certain entities that you are interested in instead of just sending back the entire batch of information with all of your data, and searching through it on the iOS device.
Hopefully this is somewhat helpful.
If you are only planning on GET-ing some content from the web you can use the NSURL class. NSURL *lru = [NSURL URLWithString:#"http:mywebserver.com"] and then create a new string object from the url with [NSString stringWithContentsOfURL:lru], or any data you would like. If you are trying to hold a session or having more control over the request, I would suggest looking into the NSURLSession class.
Im trying to send some data to a form on a site were im a member using cURL, but when i look at the headers being sent, they seem to have been encrypted.
Is there a way i can get around this by making the computer / server visit the site and actual add the data to the inputs on the form and then hit submit, so that it would generate the correct data and post the form ?
You have got a few options:
reverse engineer the JavaScript that does the encryption (or possibly just encoding) process
get a browser engine (e.g. the Gecko engine), and add some scripting to it to fill in the forms and push the submit button - of course you would need JavaScript support within the page itself
parse the HTML using an HTML parser, feed the JavaScript in it to a JavaScript runtime with the correct libraries, fill in the "form" and hit the submit button
It's probably easiest to go for the first option. The JavaScript must be in the open to be able to be executed in the browser. But it may take some time to reverse-engineer as it is likely obfuscated.
You can use a framework to automate user interaction on the web pages, like Selenium.
This would enable you to not bother reverse engineering anything.
Selenium has binding in various languages, including Python and java.
Provided the javascript is visible on the website in question, you should be able to simply copy and paste their encryption routines to prepare the headers exactly as they do
A hacky fix if you can isolate the function that encodes the data you type in the form - is to use something like PyV8 to execute the JS inside python.
Use AutoHotKeyIt and actually have it use the Browser Normally. It can read from files, and do repetitive tasks infinitely. Also you can push a flag to make it only happen within that application, which means you can have it minimized and yet still preform the action.
You seem to be having issues with the problem of them encrypting the headers and such, so why not simply use that too your advantage? Your still pushing the same data in, but now your working around their system. With little to no side effect too you.
I have been using a storyboard, and I have not gotten into the code much, and now it seems that it is time.
I have a form and when the submit button is pressed, do I need to put code to handle that into the .h or the .m file? Also, are there examples of handling a button and making a remote call that I can reference somewhere?
Thanks!!
You might find Apple's Your First iOS App document helpful; it covers connecting buttons to actions in code.
As for making a remote call; there are many ways. I would suggest you look into NSURLConnection and friends as a stating place, but there are many, many libraries to help with this, such as RESTKit.
