項(xiàng)目中常常需要監(jiān)聽(tīng)程序的網(wǎng)絡(luò)變化搔驼，判斷用戶(hù)是以哪種上網(wǎng)方式囊榜，在網(wǎng)上搜索了一番舅柜，找到了兩個(gè)常用的監(jiān)聽(tīng)網(wǎng)絡(luò)的方法瞒窒，第一種是使用AFNetworking中的AFNetworkReachabilityManager，第二種是使用蘋(píng)果推薦的Reachability恋技，如果你以為我這里在寫(xiě)下它倆的用法拇舀，那你就錯(cuò)了（好吧，是我錯(cuò)了蜻底，還是要寫(xiě)下這兩個(gè)的用法）骄崩。請(qǐng)看標(biāo)題，為什么叫真·實(shí)時(shí)監(jiān)聽(tīng)網(wǎng)絡(luò)變化，這兩種方法確實(shí)能監(jiān)聽(tīng)到網(wǎng)絡(luò)的狀態(tài)刁赖，但是有一種情況搁痛，就是鏈接上了WiFi长搀，但是這個(gè)WiFi是沒(méi)有網(wǎng)的宇弛，此時(shí)用那兩種方法只能判斷當(dāng)前設(shè)備鏈接的WiFi，無(wú)法判斷能不能連接到互聯(lián)網(wǎng)源请。努力上午搜尋了一下枪芒，發(fā)現(xiàn)一個(gè)開(kāi)源的三方挺好用，這里分享下（先貼下AFNetworkReachabilityManager和Reachability谁尸，有些情況下還是需要它倆的舅踪，做個(gè)記錄）。
以下都是在AppDelegate文件中編寫(xiě)的良蛮，有添加通知的是實(shí)時(shí)監(jiān)聽(tīng)網(wǎng)絡(luò)抽碌，未添加通知的地方如需要實(shí)時(shí)監(jiān)聽(tīng)請(qǐng)自行添加，添加完別忘移除通知(有點(diǎn)啰嗦决瞳，誰(shuí)讓我記性差)货徙。
