- afn3.x以后沒(méi)用了NSConnection瓷蛙，全部用NSSession
- 在afn中
AFHTTPSessionManager就是對(duì)Session的封裝土涝，afn中的序列化和反序列化就不在這說(shuō)碘饼，碰見(jiàn)的問(wèn)題一般都是從服務(wù)器接收值的類型的問(wèn)題和安全性問(wèn)題课蔬，這問(wèn)題網(wǎng)上一搜全都是一樣的答案
.h文件中,在里面需要注意的一個(gè)點(diǎn)是：上傳圖片的時(shí)候烁峭，我們自定義的圖片名中不能出現(xiàn)數(shù)字容客，我的一出現(xiàn)數(shù)字就會(huì)打印上傳失敗，不知大家有沒(méi)有遇到過(guò)
