What is the TAG in didReadData ?

[Flo]

Hello mates,

I think I understood the following:

- the tag is just used locally, which means we deal with it ourself.

- we write data in the socket queue then, when data has actually been written,  the didWriteDataWithTag delegate methods is called. So the tag is the one we initially set at first.

But what about the tag that is in the didReadData delegate method ? Since data comes from some other remote peer, what does this tag refer to ?

Thanks a lot!

Hi

The tag you get in didReadData is the one you set when you write data.
That way you can differentiate between different ways of handling the
incomming data.

Calling readData you give a task to the socket to read. Your can send as
many tasks as you like before the others get complete actually. At the
end didReadData will be invoked when the data has been read. In order
for you to distinguish which data has been actually read you use the
TAG, formerly provided by your self.
