ios voip 推送-傾城孤月

1. 什麼是voip推送和普通的ios推送有什麼區別呢？
   普通推送分爲：遠程推送和本地推送，區別網上資料太多了，簡單說一下，好比網易新聞，有什麼大的新聞會在手機端接收到推送，這個就是遠程推送，是把相關信息推送到蘋果推送服務器-APNS，太簡單了，不說了！

重點說下：voip的重點功能。
就是打視頻或者語音電話的時候推送功能，一個典型的應用場景，A用戶撥打B用戶視頻或者語音電話，A撥打，B鈴聲響起，此時A掛斷，B鈴聲消失，就至關於控制對方手機同樣。國外的語音視頻電話都是採用voip push,好比whats app，line等語音視頻通信軟件。

曾經有人說普通推送能夠作到以上功能，我能夠明確的給出回覆：普通推送是沒法作到的，必須用voip push才能作到。

注意事項：
一、證書的製做過程當中也須要選中voip認證。

二、在xcode開發中也須要進行相關的設置，設置以下：

三、引入開發包

xcode端代碼以下：

一、首先註冊爲voip推送：

-(void)registerVoipNotifications{ PKPushRegistry * voipRegistry = [[PKPushRegistry alloc]initWithQueue:dispatch_get_main_queue()]; voipRegistry.delegate = self; voipRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP]; UIUserNotificationType types = (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert); UIUserNotificationSettings * notificationSettings = [UIUserNotificationSettings settingsForTypes:types categories:nil]; [[UIApplication sharedApplication]registerUserNotificationSettings:notificationSettings]; } 

在應用初始化方法中調用：

[self registerVoipNotifications]; 

二、獲取token，用於發送到服務器端，服務器端發送推送消息時，會發送這個token到APNS服務器，APNS經過這個token定位到手機和對應的應用，進而推送消息。

- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type{ NSString *str = [NSString stringWithFormat:@"%@",credentials.token]; NSString *_tokenStr = [[[str stringByReplacingOccurrencesOfString:@"<" withString:@""] stringByReplacingOccurrencesOfString:@">" withString:@""] stringByReplacingOccurrencesOfString:@" " withString:@""]; NSLog(@"device_token is %@" , _tokenStr); } 

三、下面是最重要的一步：就是對推送過來的消息進行解析，能夠在推送的時候設置標記，下面的代碼是獲取到標誌之後，根據標誌命令調用不一樣的方法進行處理，進而實現功能，注意這裏接收到消息定義時，若是傳過來的命令是call就建立一個本地推送，提示某人正在呼叫你，若是傳過來的命令爲cancel，就取消命令

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type{ UIUserNotificationType theType = [UIApplication sharedApplication].currentUserNotificationSettings.types; if (theType == UIUserNotificationTypeNone) { UIUserNotificationSettings *userNotifySetting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:userNotifySetting]; } NSDictionary * dic = payload.dictionaryPayload; NSLog(@"dic %@",dic); if ([dic[@"cmd"] isEqualToString:@"call"]) { UILocalNotification *backgroudMsg = [[UILocalNotification alloc] init]; backgroudMsg.alertBody= @"You receive a new call"; backgroudMsg.soundName = @"ring.caf"; backgroudMsg.applicationIconBadgeNumber = [[UIApplication sharedApplication]applicationIconBadgeNumber] + 1; [[UIApplication sharedApplication] presentLocalNotificationNow:backgroudMsg]; }else if(([dic[@"cmd"] isEqualToString:@"cancel"]){ [[UIApplication sharedApplication] cancelAllLocalNotifications]; UILocalNotification * wei = [[UILocalNotification alloc] init]; wei.alertBody= [NSString stringWithFormat:@"%ld 個未接來電",[[UIApplication sharedApplication]applicationIconBadgeNumber]]; wei.applicationIconBadgeNumber = [[UIApplication sharedApplication]applicationIconBadgeNumber]; [[UIApplication sharedApplication] presentLocalNotificationNow:wei]; } } 

四、注意當進入應用時，角標清除：

- (void)applicationDidBecomeActive:(UIApplication *)application { [UIApplication sharedApplication].applicationIconBadgeNumber = 0; }
