通常來說項(xiàng)目中的推送功能一般是使用第三方來實(shí)現(xiàn)轻抱，可以極大的降低開發(fā)時間及成本祈搜，下面就簡單介紹下關(guān)于極光推送的一個簡易封裝使用

集成步驟及使用注意點(diǎn)

/*  遠(yuǎn)程推送集成指南 （使用極光SDK）
 
 1、準(zhǔn)備生產(chǎn)泽西、開發(fā)環(huán)境.p12文件  http://docs.jpush.io/client/ios_tutorials/#ios_1
 
 2缰趋、下載需要集成SDK    http://docs.jpush.io/resources/#sdk
 
 2.1 下載 JPush-iOS-SDK 秘血，得到一個lib 和一個Demo，將lib 導(dǎo)入項(xiàng)目中仔涩；
 libz.tbd  ---》 注：Xcode7需要的是libz.tbd粘舟；Xcode7以下版本是libz.dylib
 2.2 同時創(chuàng)建并配置PushConfig.plist文件在 SDK目錄下
 2.2 注冊帳號：https://www.jpush.cn柑肴；
 2.3 添加應(yīng)用名，上傳對應(yīng)環(huán)境的.p12文件适秩；此步完成后得到一對字符串 AppKey 和 MasterSecret秽荞；
 
 3抚官、在 AppDelegate.m 中復(fù)制如下代碼：

------AppDelegate.m 的調(diào)用示例------------------------------------------------------------
 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
 
 //配置推送
 [ZQPushManager configurePushWithOptions:launchOptions];
 
 return YES;
 }
 - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
 {
 [ZQPushManager registerDeviceToken:deviceToken];
 }
 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
 {
 [ZQPushManager handleRemoteNotification:userInfo];
 }
 -(void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler
 {
 [ZQPushManager handleRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
 }
 
 - (void)application:(UIApplication *)application didReceiveLocalNotification:(nonnull UILocalNotification *)notification
 {
 [ZQPushManager handleLocalNotificationForRemotePush:notification];
 }
 - (void)applicationWillEnterForeground:(UIApplication *)application {
 [ZQPushManager configurePushWithOptions:nil];
 }
 - (void)applicationWillResignActive:(UIApplication *)application {
 [ZQPushManager sharedManager].justInBack = YES;
 }
 ------AppDelegate.m 的調(diào)用完成---------------------------------------------------------- 

 4胁住、打包給測試開發(fā)刊咳、生產(chǎn)環(huán)境，發(fā)布appstore配置余指；
    測試地址包：端口地址為測試環(huán)境酵镜，證書使用開發(fā)證書，測試手機(jī)直接連接電腦安裝垢粮；
    正式地址包（避免線上正式用戶收到）：端口地址為正式環(huán)境靠粪，證書使用生產(chǎn)證書，測試手機(jī)用ad-hoc包安裝昔善；
    發(fā)布appstore：端口地址為正式君仆，證書使用生產(chǎn)證書牲距，發(fā)布；
 
 4.1 PushConfig.plist配置說明洛姑；
    APS_FOR_PRODUCTION （備用參數(shù)，暫時不需要配置）：0表示開發(fā)證書参咙，1表示生產(chǎn)證書；
    CHANNEL（不需要配置）：在工程 - TARGETS - BuildSetting - SearchPaths - User Header Search Paths
            添加PushConfig.plist在工程中的相對路徑（列如：$(SRCROOT)/plugIn/JPush/PushConfig.Plist择同，plugIn敲才、JPush為文件夾））
    APP_KEY：配置為極光開發(fā)或者生產(chǎn)AppKey择葡；
    
    注意：極光目前通過同一個賬號來區(qū)分開發(fā)和生產(chǎn)環(huán)境敏储，而我們后臺是通過兩個極光賬號區(qū)別環(huán)境（測試賬號對應(yīng)極光開發(fā)環(huán)境，正式賬號對應(yīng)生產(chǎn)環(huán)境）妥箕，極光并不通過賬號來區(qū)分ios的環(huán)境。
 4.2 ZQPushManager.m里在clickRemoteNotification里配置app端口地址坎吻；
    

 5宇葱、細(xì)節(jié)注意：
     method_2 didReceiveLocalNotification
     method_1 didReceiveRemoteNotification:(NSDictionary *)userInfo
     fetchCompletionHandler:
     
     * 在iOS7.0之后，在前臺收到遠(yuǎn)程通知吗氏，或者點(diǎn)擊了后臺的通知弦讽，都會調(diào)用method_1的方法 膀哲，userInfo就是收到的通知，可根據(jù)需要做相應(yīng)的處理仿村；
     
     5.1 后臺收到的遠(yuǎn)程通知蔼囊，會自動下拉彈出衣迷，而前臺收到時，不會彈出云矫，需要單獨(dú)處理让禀，一般的做法有3種：
     5.1.1 轉(zhuǎn)化成本地通知陨界，丟到通知欄；
     5.1.2 轉(zhuǎn)化成AlertView彈出吼肥；
     5.1.3 定義一個和系統(tǒng)通知一樣的效果彈出缀皱； (PS：這個我還沒實(shí)現(xiàn) )
 
     5.2 判斷用戶是否允許通知；
     5.2 5.1.1轉(zhuǎn)換成本地通知時表箭，會調(diào)用一次method_2钮莲；點(diǎn)擊通知欄的本地通知時會再調(diào)用一次，要做區(qū)分极舔；
     5.3 未獲得通知授權(quán)時候的跳轉(zhuǎn)： @"prefs:root=NOTIFICATIONS_ID&path=com.365sji.iChanl"拆魏；
     5.4 應(yīng)用內(nèi)注銷遠(yuǎn)程通知慈俯；發(fā)送一條極光指定的通知 kJPFNetworkDidCloseNotification贴膘；
     5.5 開啟和注銷之間的快速轉(zhuǎn)換：
     當(dāng)用戶前往5.2，就判斷可能重新激活通知洋闽，此時在willEnterForground重新注冊通知氛琢；
