I guess something like this would work (not very good at iphone stuff):

// 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 a class name opens up the docu for this class along with a list of methods and so on. Take a look there, too!
