Loading data files in iPhone project

How does one read a data file in an iPhone project? For example, lets say I have a static file called "level.dat" that is structured as follows: obstacles: 10 time: 100 obstacle1: 10,20 ...

I would like to read the contents of the file into a NSString then do the parsing. How do I read the contents of a file into a string? Also, where in the project should the "level.dat" file reside? Should it be under "Resources" or just in the main directory?

Thanks in advance!


See this answer: How to fopen() on the iPhone? which shows how to get access to resources in your bundle. Once you have the path, just use [NSString stringWithContentsOfFile:encoding:error:].

NSString   *path = [[NSBundle mainBundle] pathForResource: @"level" ofType: @"dat"]
NSError    *error = nil;
NSString   *data = [NSString stringWithContentsOfFile: path 
                                             encoding: NSUTF8StringEncoding 
                                                error: &error];
