Просто настройте этот словарь, вот как записать plist в каталог приложений.
NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"Name", @"Ramesh", @"Address", @"Delhi", nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"dictionary.plist"];
[dictionary writeToFile:path atomically:YES];
