百度云推送支持IOS和Android的云推送。Android支持的還不錯(cuò)，但是IOS一般很難調(diào)通。百度云對(duì)于IOS的推送來(lái)說(shuō)，他只是做了一個(gè)中間的代理，為用戶提供接口，優(yōu)點(diǎn)是使用百度云推送，Android和IOS可以統(tǒng)一管理；缺點(diǎn)是：調(diào)通不容易，用戶的IOS證書(shū)需要上傳驗(yàn)證，會(huì)直接暴露給第三方，并且IOS的apns支持用戶自己構(gòu)建provider服務(wù)器，與apns直接通信。
個(gè)人建議：Android使用百度云推送，IOS的使用自己構(gòu)建的provider與IOS的apns直接通信。與IOS的apns直接通信有許多實(shí)現(xiàn)，Java、PHP、object-c、c++，在我的博客中有一篇是使用erlang實(shí)現(xiàn)的，有興趣的可以看看。
Android實(shí)現(xiàn)推送功能百度云有自己的demo，大家可以根據(jù)官網(wǎng)（http://developer.baidu.com/wiki/index.php?title=docs/cplat/push）的步驟，首先注冊(cè)一個(gè)百度開(kāi)發(fā)者賬號(hào)，然后創(chuàng)建自己的一個(gè)應(yīng)用，根據(jù)例子百度云服務(wù)器會(huì)自己生產(chǎn)一個(gè)客戶端的demo，可以運(yùn)行在Android的手機(jī)上。然后在頁(yè)面進(jìn)行推送實(shí)驗(yàn)。當(dāng)然也可以下載百度云推送服務(wù)器，然后通過(guò)運(yùn)行使用服務(wù)器推送，官網(wǎng)中有php、Java、Python、node.js、c#實(shí)現(xiàn)。
步驟：1、首先將上面你建立的工程中百度云服務(wù)器為你生產(chǎn)的例子demo安裝到手機(jī)上，然后以自己注冊(cè)的開(kāi)發(fā)者賬號(hào)登陸，里面有一個(gè)userid和channelId,channelId記錄下來(lái)，UserId和開(kāi)發(fā)者上的對(duì)應(yīng)一下，然后決定使用哪一個(gè)，如果一樣，那沒(méi)問(wèn)題，不一樣的話一般采用注冊(cè)者頁(yè)面中的那個(gè)。也可以通過(guò)Android服務(wù)端獲取的數(shù)據(jù)分析出userid。
給用戶發(fā)送消息分幾種情況分別如下：給某個(gè)用戶的所有設(shè)備發(fā)送信息此時(shí)需要用戶的userid；給用戶的某個(gè)設(shè)備發(fā)送信息此時(shí)需要用戶的userid和channelid；給某類用戶發(fā)送信息，需要tag分類，也就是給該類的所有用戶發(fā)送信息。
