I am a developer who is still learning . I want to design an app which can allow multiple people to have a video conference/chats simultaneously something like zoom . I know i can design native apps like specific for Android as well as iOS but I am still learning Android development and have no idea about iOS code .I searched and found that we can have hybrid apps having React,Node.js or with Angular.js and they work on different platforms .But as I'm a newbie I need suggestions as well as guidance .what I'm expecting in my app are following things :
Should support all video resolutions and audio quality, should
work in low and high network scenarios
Should be low on usage of power/ processor
Should not have any external hardware dependency
Should work on any device
Should have chat option during conference, even the multi
people conference
Should have sign-in and non-sign-in options to join a
conference
Can be browser and/or app based interface
Should have encrypted network communication
Should have audio/ video recording feature
Should have screen/file sharing capabilities
Should allow audio to close captioning during chat
(multilingual)
Should have capabilities to host multiple concurrent
conferences having multiple participants in each conference
I know its a tedious task to involve everything I discussed but I need guidance how to do this .
I have already told my expectation so now I want to know what steps I need to do so ,How to start as well as where to start ,what language/library I should choose ,whether having a hybrid app be a good idea or should I go for native apps .As I have earlier said I am a learner so I am going to learn each and everything to get my project done ,so whether its react or node or angular or whatever experienced developer are going to suggest/guide here .I know my question may look broad or even vague but still I am asking only because I see stack-overflow as a group of supportive accomplished coders .Hope you guys will help me in getting my project done .Thank you !
OK then you have got much work to do. I will point you to some references which should give you a good start. I will try to keep this as short as possible.
As you mentioned, WebRTC is the way to go.
With WebRTC, you can add real-time communication capabilities to your
application that works on top of an open standard. It supports video,
voice, and generic data to be sent between peers, allowing developers
to build powerful voice- and video communication solutions. The
technology is available on all modern browsers as well as on native
clients for all major platforms.
This blog explains how WebRTC functions in details - https://medium.com/#anto.christo.20/understanding-web-real-time-communication-webrtc-d4cec5a43f2f
This blog explains how to build peer2peer video calling in android -
https://medium.com/#anto.christo.20/understanding-web-real-time-communication-webrtc-d4cec5a43f2f
https://webrtc.org/ also contains lot of headstart material including sample code.
Once you have done this you can add other features on top of it.
Now, this will take care of peer2peer but if you want o build a multi-user functionality from scratch there is some extra work required as mentioned in the answer - how to build multi-user video chatting web app using webRTC, node.js and socket.io
This is a very basic question, but I have no idea how to be begin, so please bear with me.
I'm a C# software developer, so I'm very familiar with the VS IDE and with Windows and Web development. But I have never developed a mobile application.
With that said, I came up with an idea which is essentially a screen with a map and a bunch of pins, and a list that represents each pin. It will run in an iphone and android phone. It will look something like below.
I decided to develop it in Xamarin because 1) I've worked with VS for many years so I understand how it works, 2) I can develop one app in Xamarin that can run both in ios and android.
I understand that it may be a very basic question, but I have no idea where to start. I also have experience with development, so I don't want to go thru the Hello World example. Finally, I also have a full-time job, so my limited free time would be used to completing this particular app.
So my question is: where do I start?
First thing first. You should get yourself familiar with Mobile Development(app life cycle, patterns etc.) by creating few sample applications (since you stated you were developing in Visual Studio using c# before it should be quick procedure for you). You can find documentation and sample codes on official Xamarin site:
Xamarin Website
Next get yourself familiar with MVVM pattern and MVVM frameworks to write applications using modern patterns and modern practises. I personally recommend MVVMCross or MVVMFresh.
Data Binding from Official site
FreshMVVM with Samples
Then get yourself familiar with Xamarin.Forms maps. It's a nice library that allows you to use one code and share them across 2 platforms. Google Maps official apis are also good but they are platform specific.

Enjoy and welcome to the Dark Side ;)
What is the best application or programming languages to build an iOS application platform for chat application for beginner like me. Please anyone can tell me about it.
Apple put a lot of effort in its new `Swift' language.
On any Mac computer, you will find XCode on the app store.
iBook has a nice and clear electronic copy of the guide.
I've gotta admit I was a bit circumspect ("yet a new language ?") but it appears has they sell it, solid and sound.(It's compiled and based on llvm. It is open as well, perhaps MIT license?)
I think they basically came up with C# for iPhone (it may even spawn from `mono'?)
But, again, the license model for the source make it sound more promising.
I found the iBook guide for very comprehensive when it came to the very basic of the language and the libraries.
XCode comes with quite a few templates showcasing each major application type. (You can also check the other languages for yourself: Objective-C and javascript)
So the two complement nicely.
If you are starting from scratch, I see no reason not to start on this train.
Since it's straight from Apple, and if coming up with Android isn't yet part of your plan, it will also be your path of least resistance when it comes to technical difficulties.
I am absolutely new to Mobile App Development and was looking for an appropriate platform to start off with. I came across a project where people are looking to implement self-help advertising for a switch and home automation company into a mobile app. They want an iPhone App initially but also want to deploy on Android and other platforms subsequently. A similar app is this one.
After investing a fair amount of time in researching about various SDKs and Developer Programs, Marmalade caught my attention with it's multi-platform deployment feature. However after going through a few tutorials, of which I found these quite helpful, I observed that more often than not the tutorials concern Game Development. So, I was wondering if Marmalade is a more appropriate platform for Game Development and if I am looking to develop a general application I should perhaps consider a native SDK?
Marmalade is great for games: among the games that use Marmalade are Cut the Rope, Plants vs Zombies, Call of Duty: Black Ops, etc
But for general apps you should better use some other tool at least till their Marmalade 6.0. They have native UI support but it's still in development and you may miss some features.
Look at Titanium: http://www.appcelerator.com/showcase/applications-showcase/
I always prefer to use native language for the app development due to easily available help and tutorial for them. You can find lot's of help and tutorial, guidelines, books etc. for Android or Objective C development, but their are very few tutorials on Marmalade.
Marmalade is a great engine for any game developer, but for a non-gaming app, I'd not recommend it, since you'll never need to use the extra features which are it's USP.
I am just starting iOS development. I read some tutorials, watched stuff on iTunes U and wrote some sample code myself. Now I want to take the next step. I want to learn about best practices for iOS development in XCode.
Are there any well written and well organized iOS projects that one could take a look at?
(As I see it, iOS is not exactly the place for open source enthusiasts, however.)
Thanks
Mike.
I agree with several of the other answers that state that looking at many, many projects for mini-examples of what you want to do in your own app is the way to go.
However, you asked for an example of an app demonstrating best practices.
You could do worse than to read Matt Gallagher's blog, Cocoa with Love from beginning to end. However, the app example you asked for is right here.
Not only will it show a variety of techniques, some novel design and best-practices, but also he points out where he feels that he might have done something better.
It's a great read.
I would suggest the following process: (it worked for me)
Think of an advanced app. that you eventually want to be proficient enough to create.
Make a top-down problem-solving tree containing the necessary skills required to build your final app.
Use this tree to divide your final app. into 'sub apps'. Start at the bottom of the tree, find a tutorial specifically for that skill, and make a "Hello World" app. that uses that skill.
Keep progressing upwards, creating 'sub apps' as you go.
When you are finally ready to make your final app. (it will take a while), you will have a good handle on how iOS development works. It will also be a great test of your knowledge via direct application!
Getting the hang of iOS development can be tricky; it really does require a top-down approach, and every online resource I've found takes a linear one. The only way that I think a linear approach to learning iOS development would be manageable, is to take it one small task at a time.
As for specific resources, I always google "[what I want to do] iPhone SDK" and browse the tutorials and forum posts that come up.
Here are some open source iOS apps. However, they aren't very well documented and are also very advanced.
TKAWebView - A subclass of UIWebView that handles authentication and downloading.
Welcome to your Mac - An iOS app. to VNC into a PC/Mac and do some cool stuff.
InAppSettingsKit - A settings screen creator for your apps.
Good luck!
The people behind the Parse platform have made two complete projects.
For each project there is the complete source code, a tutorial and the resulting app is also available from the AppStore.
Anywall: https://parse.com/anywall
Anypic: https://parse.com/anypic
They both rely heavily on the Parse platform as the data source, but you still get a feel for an iOS project.
Molecules is a great open-source app that uses 3D OpenGL to render complex models of molecules.
Just keep coding my friend. You'll learn over a period of time. The best way to get dirty in a mud fight is to jump into it... Weird analogy but you get the point.
Maybe someday, we all will learn from you then !
Like you said there many and many source codes are available internet, but most are incomplete.
I found some Open source codes of REAL application currently available through Apple app store are given here
Free iPhone App Source Codes of real apps
and also, you can find many answers here on stackoverflow question - Are there any Open-source iPhone applications around?
You can download free IOS sample projects from http://devcodemarket.com
I realize this is an old thread but I've also been looking for good objective-c code examples recently and I just realized that TextEdit's source code is available at the Mac Developer Library webpage.
Also, here are some popular objective-c libraries that have caught my attention:
CocoaPods
AFNetworking.
you can also go through UICatalog from Developers Library and download the sample code. just google it and you will find a project containing all basics of iphone.
I don't think there is any perfect project that can demonstrate all the qualities of great code. Developers have stylistic preferences and may make mistakes. That said, you should look at a lot of different projects and try to look at the conventions used.
I'd suggest starting on GitHub. Besides for seeing code, you'll see what libraries are out there, which may help further your projects later on. Here's the Objective-C page on GitHub.
(Also, I (GitHub link) think you're wrong about iOS devs not being in favor open source. Yes, there's money to be made, but you can't sell a CSV paring library on the App Store as is.)
Have a look at https://github.com/mozilla/firefox-ios
That is Firefox for iOS, written in Swift.
Cocoacontrols has a wide range of controls written using Objective-C & Swift.
I believe these days, this is one of the most famous website for iOS Developers.
But, before you jump onto this, you have to learn Objective-C & Swift very well, so that you will understand how to use the controls in your app which makes your app smooth.
