How to create and update data files?
Post: #1
I've read through the documentation but don't see any real samples on how to create, open, write, and update files. I want to store my game data so that when a call comes through the game will save it's state and reload on resume. Can someone point me to a sample that shows how to do this? Or maybe reference material? I know how to do this in C++ and C# and even on the XBOX but am not sure how and where to create files on the iPhone.
Help would be much appreciated.

"Where" is pretty well covered in "File and Data Management" in the iPhone OS Programming Guide. It also covers a few methods of "how."
You can of course write data to a file in many different ways. If you want to write your own binary file, that can obviously different than simply writing a string, or a property list (like a dictionary or array). You can use the standard C library functions, the posix calls, or any of the methods in NSString, NSDictionary, NSArray, NSData, NSCoder subclasses, NSPropertyListSerialization. It depends on what you want to write.
