最近看了不少關(guān)于ios藍(lán)牙語音通信的文章，網(wǎng)上錯誤不少。最近自己寫了個小Demo。

10年積累的成都做網(wǎng)站、網(wǎng)站設(shè)計經(jīng)驗，可以快速應(yīng)對客戶對網(wǎng)站的新想法和需求。提供各種問題對應(yīng)的解決方案。讓選擇我們的客戶得到更好、更有力的網(wǎng)絡(luò)服務(wù)。我雖然不認(rèn)識你，你也不認(rèn)識我。但先網(wǎng)站設(shè)計后付款的網(wǎng)站建設(shè)流程，更有南山免費網(wǎng)站建設(shè)讓你可以放心的選擇與我們合作。

具體的每個函數(shù)干什么的請自行查詢。都是Gamekit框架的api。

代碼實現(xiàn)如下

- (void)viewDidLoad

加紅的方法大家注意下。第一個加紅的方法如果不寫可能也能實現(xiàn)，但會有一些內(nèi)存上的錯誤。關(guān)閉藍(lán)牙連接不是簡單的   [_session disconnectFromAllPeers];就行的  要像第二個紅色方法里那寫全才能真正正確關(guān)閉。（水平有限歡迎拍磚）。源碼至http://down.51cto.com/data/703329下載。或聯(lián)系478043385@qq.com免費索取。
