四菊卷、網(wǎng)絡(luò)環(huán)境判斷
?1、Reachability?類名
?(1)導(dǎo)入Reachability類名
?(2)初始化Reachability對(duì)象逗鸣，HostName?盡量用一個(gè)比較穩(wěn)定的網(wǎng)絡(luò)
?(3)添加觀察者板熊，接收網(wǎng)絡(luò)環(huán)境發(fā)生改變的通知
?(4)開始監(jiān)測(cè)
?(5)在通知中得到Reachability的對(duì)象
?2、AFNetWorking中AFNetworkReachabilityManager
?(1)導(dǎo)入類庫(kù)
?(2)創(chuàng)建檢測(cè)對(duì)象 類方法sharedManager
?(3)開始監(jiān)測(cè)
?(4)通過檢測(cè)對(duì)象?獲得檢測(cè)結(jié)果 回調(diào)方法（setReachabilityStatusChangeBlock:）
