學(xué)而時(shí)習(xí)之雀鹃，不亦樂(lè)乎，大家好励两，我是張杰黎茎。
iOS開(kāi)發(fā)做久了不免就是復(fù)制了黏貼了，代碼積累多了就不想敲了当悔，高級(jí)一點(diǎn)的對(duì)UI也做了不少輪子傅瞻。下面要寫的不是UI輪子踢代，是簡(jiǎn)單的網(wǎng)絡(luò)請(qǐng)求的封裝。
一般網(wǎng)絡(luò)請(qǐng)求的封裝分為兩種：
一嗅骄、iOS原生NSURLSession以及NSURLConnection(NSURLConnection已經(jīng)被廢棄胳挎，我們就不多說(shuō)了)。NSURLSession 下面這篇講的不錯(cuò)溺森，我自認(rèn)為沒(méi)人家講的精辟慕爬，怕誤導(dǎo)讀者，故引用之屏积。

二医窿、網(wǎng)絡(luò)請(qǐng)求封裝或者說(shuō)用的最多的 AFNetworking，也是基于iOS原生請(qǐng)求NSURLSession封裝而來(lái)的炊林。用法也很簡(jiǎn)單姥卢。但是我們的APP網(wǎng)絡(luò)請(qǐng)求很多，每次都去寫一遍請(qǐng)求頭之類過(guò)于繁瑣渣聚。下面是我自己封裝的隔显，個(gè)人認(rèn)為簡(jiǎn)單明了，便于使用饵逐。

使用起來(lái)很簡(jiǎn)單括眠，打印的信息也很齊全，請(qǐng)求頭倍权，請(qǐng)求參數(shù)掷豺，請(qǐng)求地址等一目了然。
