I’m new for OpenGL ES 2.x on iOS, and I’m trying to render some characters in the OpenGL ES 2.x scene. But I don’t know how to do it.
So anyone who can point me in the direction of an Objective-C tutorial or post some sample code?
Any help or advice would be much appreciated.
This question is asked a lot because OpenGL does not have built-in support for text fonts. There is a good survey of solutions and discussion here:

http://stackoverflow.com/questions/18557535/text-font-rendering-in-opengles-2-ios-coretext-options-and-best-practice
But the easiest solution by far is to use the Print3D class in the PowerVR SDK:

I new to iOS development. I working on CIFilters and I want to make custom filter using metal framework in iOS.
But I couldn't find any beginner level resources that could help me to understand the process step by step.
Is there any book/video tutorials or something that teaches Metal ?
Here you will find apple documentation, sample code, and videos. link
This website is will help you to understand metal: link

I've been looking at a lot of tutorials trying to find a way to make an OpenGL app written in Swift, but I can't seem to find a good template to use.
Most tutorials suggest using a blank one, but then I have to write a ton of files (such as AppDelegate) all from scratch, which I have no clue how to do.
I tried all the links on this, but the first one doesn't even work and the second one is in Objective-C.
Anyone have anything that might help me?
I ended up figuring it out myself by using GLKit and smashing together old tutorials. Since OpenGL is just a bunch of functions, all you really need to do is find the right parameters for your programming language.
For anyone else trying to do this, there's some fairly useful resources here and here, and it's also useful to shove in some ported code from Ray Wenderlich if you get stuck. Good luck!
I am trying to figure out how to use OpenGL in Xcode five but I cannot figure it out. Is there a relatively good tutorial out there to help with this? I am not looking for the best opinions. I am just looking for a list of some that might help. I have found a couple but they seem to be outdated. Thanks.
This link will give you a basic tutorial in how to get started on OpenGLES 2.0 on iOS.
It goes over the basic principles of vertex and fragment shaders. It also goes through the creation of objects, and some basic animations.
I should load a 3d model (let's say a fridge) and scale or rotate it to locate on a kitchen photo (just for an example).
I have seen several SDKs but all was for 3d games. What I need is to put and play with my object in a native IOS app.
Where should I start? GLKit is the answer for that?
iOS 3d rendering is made by OpenGL ES, that is a pretty difficult topic. Apple provides GLKit to help developer to integrate OpenGL ES but none of is a model parser or scene manager, is hard anyway. I can suggest you to use a 3d engine, I took a look at two engines:
1-Nineveh GL
2-Irrlicht
The first integrate absolutely fine in iOS projects and exposes objective c API. It uses only OpenGl 2.0 shaders. The problem is that is a beta version.
The latter is written in C++ and supports both 1.0 and 2.0, but is pretty hard to integrate.
I was wondering what project type this application was probably developed using?
The app is called Sound Literacy.

I'm new to developing, but want to create an application that uses these same features. I'm thinking either OpenGL ES Application or View-Based. What do you guys think?
Thank you in advance!
The "project type" really doesn't matter. All it does is give you different boilerplate code to start with. So start with whichever one seems most convenient to you.
I would say OpenGL ES since it's a lot more customizable.
