使用XCode将外部项目添加到我的iPhone应用程序

Question

Just starting to poke around iPhone development. I am trying to add an external project/library to mine (specifically the ASIHTTPRequest, http://allseeing-i.com/ASIHTTPRequest/ ).

I am at a bit of a loss as to how I go about actually adding this dependency to my project. I come from a Visual Studio/C# world, and in Visual Studio I know I would "Add Existing Project" to my solution file and then add a reference to the new project to my own. Or, alternatively, reference the DLL directly if it is already built.

The ASIHttpRequest project is on GitHub, and provides full source code. I just don't have any idea about how to actually get this dependency into my own project. I tried "Project -> Add To Project", and just selected the folder ASIHTTPRequest extracted out into. I see it as a sub-folder to my project now... but get a ton of build errors. I removed everything but the .h and .m files from this subfolder, and now I don't get any build errors from those resources anymore, but trying to reference a ASIHTTPRequest object in my own project gives "undeclared" errors.

Am I missing something here? Can I not of these .h and .m files in subfolders?

You're on the right track. You just need to #import the ASIHTTPRequest header in the file where you want to use it. You do have to make sure you've met all the dependencies specified on the ASI site , but once you've done that, everything should work right by just doing an import like you've described. Once all that is set and everything is compiled, add this:

#import "ASIHTTPRequest.h"

to the top of the file where you want to use the library.
