SL在iOS的SLComposeViewController中代表什么？

Question

I searched a number of sites to find out what does SL in SLComposeViewController represent or stand for? IMO, it represents Social Linking. But I couldn't confirm it anywhere on the internet.

Answer 1

Its just SOCIAL Compose View Controller. SL stands Social.

Answer 2

它是社交框架的一部分，因此SL是SociaL的缩写。

Answer 3

How about "Social Layer" or "Social Library"?

From documentation, SL* classes allow to do lots of things, such as:

"Create a network session. Get the activity feed for a user. Make a new post. Set properties on a post, add attachments, etc. Publish a post to an activity feed."
