Socket.IO Library Obj-C error - ios

I started implementing Sockets with Socket.IO in my apps and web applications, I tried using different libraries for iOS (socket.IO-objc & RocketIO) but they both display an error when I try to run it.
Maybe someone can help me :)

Thank you so much

Add libicucore.dylib to your project.
That was a issue on SocketRocket github (that I suspect to be on se same basis that the ones you're using).

glGenVertexArrays and glDeleteVertexArrays not resolved for Windows

I am trying to port iOS projects to Windows 10 using Windows Bridge for iOS.
But I am stuck to the unresolved functions of glGenVertexArrays, glBindVertexArray, and glDeleteVertexArrays.
The original iOS project is a Cocos2d 2.x project. I am not familiar with OpenGL, Therefore I ask for help here! Thank you!
By the way, I noticed that the same issue also exists if I paste these functions into the sample project of WOCCatalog.
Thank you in advance!
Searching the repo for "glGenVertexArrays" does not return anything. Therefore, this API (along with tons of others) is not yet implemented.

Looking for an IOS version of ShowcaseView

I'm looking for a library similar to https://github.com/amlcurran/ShowcaseView
I want to be able to implement forced tutorials on new users who open my application for the first time. Does anyone know where I can find a library that helps make this easy?
You ca try https://github.com/rahuliyer95/iShowcase
This is a quite similar iOS implementation of the ShowcaseView for Android (https://github.com/amlcurran/ShowcaseView).

Using ShareKit with Xcode 5

My iPhone application is developed using Xcode 5. I want to use ShareKit library in order to share images and urls from my application. The problem is, that ShareKit seems to be incompatible with Xcode 5 (thought is says it is).
Attached screenshot to illustrate my problem:
Any help (or alternative solution for sharing images and URLs) will be greatly welcome.
It seems you both are referring to an obsolete, long time abandoned version of ShareKit. Check ShareKit 2. For easiest installation I recommend Cocoapods.
Have you followed the instructions here?
(It seems like you've added objc-class.h that has no use)
Also, consider using the native sharing class UIActivityViewController for sharing purposes.

Any available frameworks for SIP for iphone?

Im supposed to use SIP for my application. I went through some documentation regarding SIP like ietf-sip-documentation , siphon , linphone for iphone and ipod. But nowhere they have mentioned about any available frameworks or any such a thing for implementation part. There are lot of things that are yet unsettling to me about SIP. I would love to get a little more clarity on this. Any help would be appreciated.
EDIT: I would want to know whether there are any frameworks available for ios or should we create our own classes for the interface?
Thanks
Doubango framework http://doubango.org/ / https://code.google.com/p/doubango/ also does a nice job here. C-based, so you would probably like to do your own Objective-C wrappers.
How about resiprocate or PJSIP? Both can be compiled for iOS. Do you also need RTP and media handling? If so, PJSIP has that built in as well.
