I have been looking for a packet/library with a file browsing capability for WebDAV, which I could use for my project in objective c, using xcode 5.1. so far the best I have found is GDFileManagerKit. but it still has stuff unsupported by my ARC such as AFNetworking version used. I do not want to alt the code of this library since it requires many changes. I would like to know if there is a better library or without me having to use AFNetworking version 1.
Thank you and please bear with me if this question is very novice. I am new to objective c xcode and iOS
You could use one of several free libraries, for example WTClient. Yet, every library I have seen is not using ARC, instead managing memory without the garbage collector.

For an iOS app that will eventually be ported to Android/Winphone, I would love to be able to write some re-usable libraries in c#, but author the iOS UI in traditional Obj-C and reference the library written in c# from Xcode and consume it from Obj-C.
I've found lots of docs that talk about going the other way via bindings (Obj-C -> C#), but not much pertaining to my question. Also, a similar question was asked 4 years ago here, but a lot has changed in the ecosystem, the info seems out of date, and some of the links in the answers now redirect elsewhere:
Is there a way to mix MonoTouch and Objective-C?
So, is this possible? If so how, and what's the best way to achieve it today? (Or alternately, is this a bad idea and should be abandoned?)
No, it is not currently possible to consume a C# library from Objective-C.
Note that it is usually possible to do it the other way with some ingenuity - the only real requirement is that the app must be a Xamarin.iOS app and the entry point the managed Main method. In your Main method you can call into native (C/Objective-C) code and have all your logic there.
Hoping to hear from some more experienced developers (completely new to protobufs as of yesterday). I've been researching how to get protobufs to work with iOS given that Google doesn't have a homegrown library for objective C.
Experimenting a bit, it seems there are two general approaches:
Use a third-party library - Booyah's objective C compiler - (https://github.com/booyah/protobuf-objc).
The issue is that it won't compile with protobuf 2.5.0, and requires 2.4.1. Does anyone see a compelling reason NOT to use this method and use the older version of protobufs?
Use C++ generated protobuf classes with some tweaking - (http://www.kotancode.com/2012/10/14/using-google-protocol-buffers-in-objective-c-on-ios-and-the-mac/)
This doesn't seem like a very clean approach and C++ bleeding into objective-C code doesn't sound like fun.
On a related note, I can't find any documentation on cleanly uninstalling 2.5.0 if I opted for the former approach. What's the easiest way to do this?
Thanks.
I'm trying to create an iPhone app which plays local radio station in my district. I found this player to work best for me :
https://github.com/DigitalDJ/AudioStreamer
When testing it against my requirements it did the best without any doubt.
I thought I'll use this players API and it should be straightforward(not really for a newbie). How exactly I do that is where I'm stuck now. Because when I run the player original project it runs smooth, but when I copy code inside Classes to my app, this is what happens :
Ok, I've been developing some apps(test apps) for two weeks maybe and I lack experience.
How do you usually embed/import other projects code into your code and user the other codes api?
EDIT
So per Sunil Pandey answer, this cannot be run using IOS SDK version 5.0?
EDIT 2 :
I feel like I'm really close now, have this one issue :
Receiver 'AudioStreamer' for instance message is a forward declaration
It's declared in my h file. as AudioStreamer *streamer
As said Sunil Pandey, ARC mecanism is enabled for your project. With ARC, your project require at least iOS4 on the phone.
I would suggest you to disable ARC for the file you imported from the third party librairy. So you can keep using ARC in your own code (this mean, you never use retain, release, autorelease).
To disable ARC for each file of your AudioStreamer library, refer to How can I disable ARC for a single file in a project?
You must have implemented ARC inside your project. that's why it is giving you this error.
If you are using ARC then only way to use this project library is to create a static library of your AudioStreamer lib and then import it inside your app
Or
If you don't want to use ARC inside your app then you can turn it off by following method
select your target -> Build Setting -> Apple LLVM Compiler 3.0 - Language
set Objective c Automatic Reference Counting to NO
I need to be able to compress file in an iPhone/iPad application. I know there are a few libraries out there that have this problem solved and are easy to integrate in an application, but I was wondering if there is something already implemented in Cocoa. It would help me a lot if I did not need to integrate external libraries in my project.
Do you mean something in iOS / objective-c ? If so, you do know that most objects you are using is an 'external library' i.e. the Foundation framework?
There is, shipped with every iPhone, libz which is the library for zipping / unzipping. You just include it as if it were any other framework.
However, the chances that you will, first time, use it as bug free as an existing library that's been tested for years by hundreds of other developers is slim.
Personally, I would easily choose adding a library over writing my own for something like this - it's been done before, you're just wasting time re-writing it. Try ZipArchive for a one-liner to unzip files etc. Just copy the source code into your app and press build :)
I don't think there is something like that in cocoa inbuild .. but you should have a look here - https://bitbucket.org/kolpanic/zipkit/wiki/Home
I'm about to write code for Windows that has somewhat similar functionality to the one existing in already written application for iPhone. I'm thinking of separating common functionality to form a component and compile it to both to iPhone and to Windows. This code is written in Objective C and uses RestKit and Core Data (and probably sqlite). Is compiling it for Windows a viable task? As I understand it GCC could compile Objective C on Windows but I'm unsure about the RestKit and Core Data api availability on Windows. I have seen two names that could be of use: GNUStep and Cocotron but I don't know if they will play well together with RestKit.
Note: I have no idea about iOS development so I might be confusing things. Any help is appreciated.
You will not easily be able to share this functionality between your applications. CoreData uses a custom opaque (not documented) format for the sql store. You would be hard pressed to reverse engineer this.
You will probably save a lot of time by rewriting that part for windows, rather than trying to get it working. There really isn't much iOS code that can be reused under windows, unless you have written pure C or C++.
