iOS开发-NotificationServiceExtension实现实时音视频呼叫通知响铃与震动
在之前的开发中，遇到了实时音视频呼叫通知，当App未打开或者App在后台时候，需要通知到用户，用户点击通知栏后是否接入实时音视频的视频或者音频通话。
在iOS需要为工程新建Target：NotificationServiceExtension
一、主工程配置
需要在主工程中开启推送功能，配置证书。
二、新建NotificationServiceExtension的target
新建NotificationServiceExtension的target
三、实现NotificationService
在NotificationService的方法
// 主要代码
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler- (void)serviceExtensionTimeWillExpire;
在didReceiveNotificationRequest实现呼叫响铃及震动效果。
// 通过通知的Sound设置为voip_call.caf，这里播放一段空白音频，音频结束后结束震动NSString *path = [[NSBundle mainBundle] pathForResource:@"blank_call.mp3" ofType:nil];AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:path], &soundID);AudioServicesAddSystemSoundCompletion(soundID, NULL, NULL, soundCompleteCallback, NULL);AudioServicesAddSystemSoundCompletion(kSystemSoundID_Vibrate, NULL, NULL, soundCompleteCallback, NULL);
完整代码如下
#import "NotificationService.h"
#import <AVFoundation/AVFAudio.h>
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>@interface NotificationService ()
{SystemSoundID soundID;
}@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;@property (nonatomic, strong) NSMutableArray *requests;@end@implementation NotificationService- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {self.contentHandler = contentHandler;self.bestAttemptContent = [request.content mutableCopy];BOOL playVoice = NO;NSString *chatPushVo = [self.bestAttemptContent.userInfo objectForKey:@"chatPushVo"];if (chatPushVo && [chatPushVo isKindOfClass:[NSString class]] && chatPushVo > 0) {NSDictionary *dict = [self dictionaryWithJsonString:chatPushVo];if (dict && [dict isKindOfClass:[NSDictionary class]]) {NSString *type = [NSString stringWithFormat:@"%@", [dict objectForKey:@"type"]];// type ： 0 呼叫if ([@"0" isEqualToString:type]) {playVoice = YES;// 通过通知的Sound设置为voip_call.caf，这里播放一段空白音频，音频结束后结束震动NSString *path = [[NSBundle mainBundle] pathForResource:@"blank_call.mp3" ofType:nil];AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:path], &soundID);AudioServicesAddSystemSoundCompletion(soundID, NULL, NULL, soundCompleteCallback, NULL);AudioServicesAddSystemSoundCompletion(kSystemSoundID_Vibrate, NULL, NULL, soundCompleteCallback, NULL);[self playVoiceWithContent:self.bestAttemptContent.userInfo];}}}if (playVoice == NO) {self.contentHandler(self.bestAttemptContent);}
}- (void)playVoiceWithContent:(NSDictionary *)userInfo {// iOS 10之前前台没有通知栏// 此处调用之前的语音播报的内容[self playRegisterNotifications:userInfo];
}- (void)playRegisterNotifications:(NSDictionary *)userInfo {[self registerNotifications:userInfo];
}- (void)registerNotifications:(NSDictionary *)userInfo {[self startShakeSound];
}/// 开始响铃
- (void)startShakeSound {// 声音AudioServicesPlaySystemSound(soundID);// 震动AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);self.contentHandler(self.bestAttemptContent);
}/// 结束响铃
- (void)stopShakeSound {AudioServicesDisposeSystemSoundID(soundID);AudioServicesRemoveSystemSoundCompletion(soundID);
}//AudioServicesAddSystemSoundCompletion的回调函数
void soundCompleteCallback(SystemSoundID sound,void * clientData) {if (sound == kSystemSoundID_Vibrate) {AudioServicesPlayAlertSound(sound);//重复响铃震动} else {// 移除AudioServicesDisposeSystemSoundID(sound);AudioServicesRemoveSystemSoundCompletion(sound);AudioServicesDisposeSystemSoundID(kSystemSoundID_Vibrate);AudioServicesRemoveSystemSoundCompletion(kSystemSoundID_Vibrate);}
}- (void)serviceExtensionTimeWillExpire {// Called just before the extension will be terminated by the system.// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.self.contentHandler(self.bestAttemptContent);
}/**json转成NSDictionary@param jsonString json字符串@return NSDictionary*/
- (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString {if (jsonString == nil) {return nil;}NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];NSError *err;NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&err];if(err) {return nil;}return dic;
}@end
四、使用推送
我这里使用的极光推送，注意需要设置推送的mutable-content=1字段。
五、点击通知后处理是否通实时音视频视频通话
在收到通知后，用户点击点击通知后处理是否通实时音视频视频通话逻辑。
在AppDelegate的方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
增加didReceiveRemoteNotification
// 获取启动时收到的APNNSDictionary *userInfo = [[DFPushManager shareInstance] launchOptionsRemoteNotification:launchOptions];if (userInfo) {[self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult result) {}];}
当收到通知后，在didReceiveRemoteNotification中处理是否接通实时音视频的视频通话的逻辑
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {DFDebugLogger(@"didReceiveRemoteNotification");[[SDPushManager shareInstance] handleRemoteNotification:application userInfo:userInfo completion:nil];NSLog(@"收到通知:%@", userInfo);[[SDPushManager shareInstance] setBadgeNumberMax:nil];if ([UIApplication sharedApplication].applicationState != UIApplicationStateActive) {// 登录后调用check__weak typeof(self) weakSelf = self;if (userInfo && [userInfo isKindOfClass:[NSDictionary class]]) {NSString *chatPushVo = [userInfo objectForKey:@"chatPushVo"];if (chatPushVo && [chatPushVo isKindOfClass:[NSString class]] && appPushVo.length > 0) {NSDictionary *dict = [DFJsonUtil dictionaryWithJsonString: chatPushVo];if (dict && [dict isKindOfClass:[NSDictionary class]]) {NSString *type = [NSString stringWithFormat:@"%@", [dict objectForKey:@"type"]];// type ： 0 呼叫/// 0/用户呼叫// 打开接听页面，进行接听}}}}completionHandler(UIBackgroundFetchResultNewData);
}

在之前的开发中，遇到了实时音视频呼叫通知，当App未打开或者App在后台时候，需要通知到用户，用户点击通知栏后是否接入实时音视频的视频或者音频通话。
