Answer 1

The NSPropertyListSerialization class give you the most control over writing and reading of property lists:

NSDictionary *dictionary = @{@"Hello" : @"World"};
NSData *data = [NSPropertyListSerialization dataWithPropertyList:dictionary
                                            format:NSPropertyListBinaryFormat_v1_0
                                            options:0
                                            error:NULL];

Read:

NSData *data = ...
NSPropertyListFormat *format;
NSDictionary *dictionary = [NSPropertyListSerialization propertyListWithData:data
                                                        options:0
                                                        format:&format
                                                        error:NULL];
