I try to develop an iOS app which need a lot of network calls...
I see that there is few iOS classes provide in the SDK.
Before to start I would like to know if there are any libraries or framework which stand out of the crowd? Or can you just recommend me the most used?
I've made some research on internet and I found two frameworks MKNetworkKit and ASIHTTPRequest. Anybody know them? Are they efficient?
Thank you.
Use AFNetworking.
However ASIHTTPRequest was also one of the best Framework to manage Network Call but now it's not that much in use.
Even the Developers of the ASIHTTPRequest says :
A little update: I've actually really enjoyed using AFNetworking, and
in many ways it's considerably better (probably not the right word:
'refined', maybe) than ASI. That said, you shouldn't go into it
expecting a 'like for like' replacement, and there are certain things
you may want to consider other options for (Amazon S3, which ASI
supported out of the box for example). But I'm generally really
pleased, and find it a clear, well documented library. So if you're
looking to move from ASI to something else, you really can't go wrong
with AFNetworking.
AFNetworking is more refined than ASI. Supportive Question.
I recommend you use ASIHTTPRequest.
REASON:
1.simple reliable and functional.
2.easy to handle post files (ASIFormDataRequest)
3.process provided

I am curious to know the advantages between using parse or a custom xmpp server. I am curious if parse has the capability of being used for creating a real time chat application, because I have never used parse for that use. Or would it be easier and better to use a custom xmpp server to handle messages. I am also curious if parse would be able to completely delete data off the server because that is what my application requires. As background info I have already started the project with parse, but I could switch over to another option if it is necessary.
Thanks
In my experience with working with Parse, I don't believe that it's the correct solution for your needs.
You may get things up and running at first, but as you try to scale your application, you're going to need to ramp up your servers (and cost!) greatly to handle so many requests. Parse's pricing is based on your requests count for the month. Imagine how many requests you expect one user to make in a month. Now times that by 1000.... Not very scalable, huh?
Now I don't know much about xmpp servers, but I've heard from some colleagues that applications like WhatsApp are using Erlang and TCP servers (just like Call of Duty) to handle message requests. In fact, here's an article that talks about the logistics of WhatsApps technology https://www.erlang-solutions.com/about/news/erlang-powered-whatsapp-exceeds-200-million-monthly-users
Best of luck!

As an old C/C++, C#, Java, JS, PHP programer, I just couldn't get used to Objective-C. The reasons are obvious. I want to continue developing iOS applications and continue using Xcode storyboards. But I seriously need an alternative to Objective-C, is there any powerful tool or framework alternatives that could help me get away from Objective-C?
By powerful alternative, I mean useful enough to use most of the device methods/functions easily and has a lot of online resources, tutorials, examples on it.
I would very, very strongly recommend that you get a good Objective-C book, or work through the Stanford iOS development course on iTunes U. Without Objective-C, you will get a lot less help with other languages, you won't be able to understand code samples, you won't understand the iOS documentation.
Try http://xamarin.com/ios - this allows you to write in C#. Personally I've used all those languages as well (other than C#) but actually prefer Objective-C.

I want to make an offline iPhone application that can grab text from a picture. Can anyone suggest the best library which I can use. I heard ZBAR and ZXING can be used only for barcode reading. Is there any other OCR Libraries for iOS to read text from images. I expect your valuable suggestions as soon as possible.
Thanks in Advance..!
Currenlty offline OCR is possible only with Tesseract
You can get source code here
Here is the good tutorial about how to use Tesseract
Also you can perform OCR on multiple language. You can dowlnoad other language trained data here
You might want to look here. They offer a large variation of language they can detect and i heard only the best from their framework.
You can also test the framework live: live demo
Unfortunately i think it is very expensive to use this framework. But if you want an A1(all my Breaking Bad fans ;-)) framework this might be your best shot.

So i created my first app which allows users to track there fitness information (workouts, routines, etc). I want take my app to the next step by allowing the user to create there own account and be able to access their workouts from any ios device (all they have to do is log in). I know i have to use databases, but I just don't know where or how to start this process.
Could you recommend any tutorials or perhaps a resource you used to teach yourself? I'm familiar with sql (took a course on it in university.
thanks guys, I apologize for the newb question.
There are many third-party services you can use that can take care of the backend for your app so that you don't need to worry about managing the database yourself. Two of the most popular ones are parse and stackmob. Take a look at their documentations. I personally use parse and would recommend it.
I've never written any os apps, but for applications in general.
There are many ways, one of which is getting a server/website (you can get free ones) and set up the MYSQL database to have the tables you need like users etc.
Then simply send requests via POST/GET to the server which will enter it into the database.Then when they want to login just do the reverse.
I would personally uses sockets, and probably encrypt the data. You may as-well send information such as how long they've used the app for etc.

I am building an app on iOS and on Mac OS X that talks to a server using REST. The app is expected to store data fetched from the server in a local store (preferably in a SQLlite database). I understand using Core Data is a good option, but I am looking for an example of an app architecture that works on the basis of UI Views getting notified when the SQLlite database is updated as a result of a response from the server.
I have seen a talk for Android at Google I/O that addresses this type architecture in detail. Are there any similar talks/articles like this for iOS?
You're mixing quite some different things here.First you need an interface for your restufl API. Look at AFNetworking library to handle requests to the server and build your API handler. Then use an NSFetchResultController to listen to your core data being updated and do what you need accordingly in your views. NSFetchResultController is built to be used with a UITableView but you can use it in other situations if needed.
use RestKit it's the best framework to work with Rest services.
and it's well-documented. the latest version works on top of AFNetworking.
you can find some examples there as well.
