I would like to add Technical analysis support to my financial project on iphone. And I found TA-lib on www.ta-lib.org, this library supports many indicators I need.
I would like to ask: Can I use ta-lib on my iphone development? And how I can do it, because this library is written in C language? I knew that Cocoa can compile C but how I can do it, import this library to iOS?
Any help would be appreciated.
Thanks
The iPhone SDK tools will compile most portable C code just fine (C is a pure subset of Objective C). There appears to be C source code available for the library in which you're interested. If so, you could try just including the source to the library in your iPhone Xcode project, and see if it all compiles, which it might if there are no dependency or collision problems. You may or may not need the entire library, which might help simplify things (or not).
You could also compile a separate static library, and then include that library, and the headers, in your iPhone app; but that technique may be a bit more complicated that your requirements might indicate.

I went through many links like this,this and this, but not getting good direction to move with. I need to implement some flash content in my iPhone app. Can anybody help me with some good tutorials to move on with the conversion process. Thanks in advance.
Suppose I am having a flash air iOS app and I need to convert the whole app in objective c for say adding some features like APNS then I have to do some needful. I want to convert the air iOS based app in objective c for same thing and hence need a tool like Haxe. Kindly help me with some tutorial or any other tool available. Thank you.
I would recommend to check out http://www.haxenme.org/ to support iOS
Basically, Haxe is a new language (by new, I mean different than others, not recently developed). It's compiler can compile Haxe code to target different platforms like C++ / C#, Flash, NekoVM, PHP and JavaScript. That said, its syntax is similar to Flash ActionScript.
To conclude, Haxe does not convert one language to another. It is a language in itself, which can be compiled targetting different platforms. So if you can port your {insert language name here} code to Haxe, then you can compile it to any of the languages mentioned in http://haxe.org/doc/intro
I found a speech synthesizer that supports many languages (http://espeak.sourceforge.net/index.html). But the source code that is available is written in C.
What can i do to make it work on iPhone?
Objective-C is a strict super set of C. Which means you can use any C code in your Obj-C project.
Yes, as long as it's been ported to the LLVM C-compiler. You can create a statically linked framework out of it, and then link into your project.
Apple does not allow dynamically-loaded frameworks.
Is it possible to use Objective-C++ for iOS application (iPhone, iPad, iPod touch) development?
Are there any examples and source code on the Internet?
Using ObjC++ is quite easy.
You have to declare source files with extension .mm. It will make compiler treat them as ObjC++. The same with headers: use the .hh extension.
There is another option: go to target settings and set Compile Sources As to Objective-C++.
That's all. No additional work is necessary.
Some notes: if you want to develop a native iOS app, then use Objective C. It will save a lot of time.
But in some cases using C++ is more appropriate. E.g. for cross-platform development. So you use only a little bit of Objective C for iPhone or Java for Android just to glue your code with environment. Everything else in C++. I use this for my cross-platform game development.
Another case is performance: Objective C is principally slower then C++. However it is only noticeable during method calls (in ObjC it is called messaging).
Yes, you can. Take a look at the samples and new file templates that Apple provides.
I have made apps for iPhone, but want to also code for the Android but want to know if it is first worth my time, second worth my having to learn another language, and third worth the effort in the sense that am I going to make a profit from this. Also if in any way Android code is similar, then will it be hard to bring the iOS (Xcode) files, or copy and paste my iOS code into the Android code.
It's a most definite no. As iPhone Guy pointed out, there's a major difference in the languages both platforms require. iPhone uses Objective-C whereas the Android is based on Java (don't know if it's Mobile Edition or "regular" though). In addition, it's a completely different set of APIs. iPhone uses a modified form of Cocoa called Cocoa Touch whereas the Android makes uses of Google's SDK for it. In answer to your question, you won't be able to copy/paste your code between the languages. Your Objective-C code won't compile to Java and vice versa.
Yes -- programming on the iPhone uses Objective-C while programming for Android is in Java. Although they use similar concepts, the two languages are different.
I was a Java programmer before switching to Objective C. Personally I like Objective C better than Java, but that's just a personal opinion ;)
I'd like to start developing applications for iPhone, but I'd really like to use OCaml rather than Objective-C. After some googling, it seems like this is definitely possible, but I haven't found any code snippets which actually compile.
Is it possible to write iPhone apps using OCaml? If so, could you provide a snippet demonstrating how to make calls into the Cocoa API from OCaml?
We have instructions for building an OCaml-to-iOS cross compiler on our site. We started with the patches mentioned above, but we found they needed to be modified in several ways to run on a stock iPhone/iPad. We are selling an iPhone app named Cassino that is entirely written in OCaml (except for thin wrappers to Cocoa Touch). Wrappers for all of Cocoa Touch would be a big job, but wrappers for a single application aren't so bad. And coding in OCaml is very pleasant compared to ObjC.
We also just published full sources for a small OCaml iPhone app named Portland at our site. Read more at psellos.com.
Out of the box, OCaml cannot be used to build IPhone apps. You would have to have OCaml output ARM code rather than x86 code. You would also have to build wrappers for all the IPhone API calls.
Still, these guys are going through the pain to try this.

My humble recomendation is that you focus on using Obj-C for everything. If
you really want an ML, use it only for the kernel or the interesting portion.
I would find an *ML that code gens to something like C, and then use that result
as a library to the app.
Good luck.
