Send multiple data
I am working on a turn based Game Center game and want to convert a string and an Int to NSData and send it to the other player.
This is how i convert the string:
let sendString = "Hello" let data = sendString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
This is how i convert the int:
let sendInt = 2 let data = NSData(bytes: [sendInt], length: sizeof(Int))
This work, but how do i send both instances? I only manage to send one of them.
Not sure the context you are working in, but if it's a func or a struct and you want to return two things the easiest way is usually to return a tuple.
