Answer 1

 NSString *path = @"path/to/some/file";
 NSMutableDictionary *plist = [[NSDictionary dictionaryWithContentsOfFile:path] mutableCopy];
 [plist setObject:@"foo" forKey:@"aKey"];
 [plist writeToFile:path atomically:YES];
 [plist release];

Note that you cannot write inside your own bundle; you’ll have to copy the file to somewhere within your app’s sandbox. Check out the NSSearchPathForDirectoriesInDomains function.
