I think something like this will work (not very good for iphone):

// Loading
NSString *path = ...
NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:path];

// Manipulating
NSObject *newElement = ...
[array addObject:newElement];

// Storing
[array writeToFile:path atomically:YES];

By pressing "ALT", double-clicking on the class name opens a document for this class, as well as a list of methods, etc. Look there too!
