I would like to add metadata to mp3 files in C/Objective-C (OS X).
I found several libraries (e.g. id3lib), but I have no clue on how to compile them.
Are there any tutorials on how you can do that? Is there any other framework for C/Objective-C to write ID3 tags to an MP3 file (song name, artist and coverart)?
Take a look at the id3lib Library Documentation. It provides a quick tutorial.

So, I am currently making a 1942-style game. How can/should I set up the path for my enemies? I know I could do it with CGPathRef but is there an easier way to do it? It seems pretty out of place for more complex paths like for example these 2 I'd like to implement:

(Sorry I can't directly post pictures, I need at least 10 reputation)
Or at least, I haven't found any documentation explaining how to create more complex shapes with CGPaths.
So what are your recommendations?

I would like to interact with the mp3 player the iPhone: Is possible to save a .mp3 file into Iphone music library programmatically?
If you aren't planning on distributing this through Cydia then the answer is no this isn't possible. However, if you are going the jail break route check out libiPodImport by H2CO3.

Is there any way of getting a list of, say 4, recently opened Applications? If so, how?
(Cocoa Mac)
Have a look at the LaunchServices/LSSharedFileList.h header file. Unfortunately, the functions in this file are not documented in the Xcode docs, but the comments in the file are very good. Basically, you create a reference to the list of recently opened applications by passing kLSSharedFileListRecentApplicationItems to LSSharedFileListCreate(). Then get an array of the current contents of the list with LSSharedFileListCopySnapshot().

It is possible to do that?
please give me a hint.
I would investigate ffmpeg, specifically libavcodec - this will allow you to convert static images in to a movie file (assuming you can get it to compile for iOS).
As far as adding to the iPod library is concerned, you aint going to be able to do that - you can read from the library from within an iOS app, but not write to it.
