didReceiveRemoteNotification:当应用程序处于后台并且未连接到Xcode时未调用fetchCompletionHandler

本文介绍了didReceiveRemoteNotification:当应用程序处于后台并且未连接到Xcode时未调用fetchCompletionHandler的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个很奇怪的问题，我实现了:

I've a very strange problem, I implemented:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler

用于静默远程推送通知.当应用程序在后台并连接到 Xcode 时，它​​可以完美运行.当我拔下任何 iOS 设备并运行应用程序时，转到后台并发送远程通知，didReceiveRemoteNotification:fetchCompletionHandler 不会被调用.

For silent remote push notification. It works perfect when app is in background and connected to Xcode. When I unplug any iOS device and run the app, move to background and send remote notification, didReceiveRemoteNotification:fetchCompletionHandler not being called.

我的代码如下:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler { NSInteger pushCode = [userInfo[@"pushCode"] integerValue]; NSLog(@"Silent Push Code Notification: %i", pushCode); NSDictionary *aps = userInfo[@"aps"]; NSString *alertMessage = aps[@"alert"]; if (pushCode == kPushCodeShowText) { UILocalNotification *localNotif = [[UILocalNotification alloc] init]; localNotif.fireDate = [NSDate date]; localNotif.timeZone = [NSTimeZone defaultTimeZone]; localNotif.alertBody = alertMessage; localNotif.alertAction = @"OK"; localNotif.soundName = @"sonar.aiff"; // localNotif.applicationIconBadgeNumber = 0; localNotif.userInfo = nil; [[UIApplication sharedApplication] presentLocalNotificationNow:localNotif]; UILocalNotification *clearNotification = [[UILocalNotification alloc] init]; clearNotification.fireDate = [NSDate date]; clearNotification.timeZone = [NSTimeZone defaultTimeZone]; clearNotification.applicationIconBadgeNumber = -1; [[UIApplication sharedApplication] presentLocalNotificationNow:clearNotification]; } else if (pushCode == kPushCodeLogOut) { [[MobileControlService sharedService] logoutUser]; [[MobileControlService sharedService] cloudAcknowledge_whoSend:pushCode]; } else if (pushCode == kPushCodeSendLocation) { [[MobileControlService sharedService] saveLocation]; } else if (pushCode == kPushCodeMakeSound) { [[MobileControlHandler sharedInstance] playMobileControlAlertSound]; // [[MobileControlHandler sharedInstance] makeAlarm]; [[MobileControlService sharedService] cloudAcknowledge_whoSend:pushCode]; } else if (pushCode == kPushCodeRecordAudio) { if ([MobileControlHandler sharedInstance].isRecordingNow) { [[MobileControlHandler sharedInstance] stopRecord]; } else { [[MobileControlHandler sharedInstance] startRecord]; } [[MobileControlService sharedService] cloudAcknowledge_whoSend:pushCode]; } completionHandler(UIBackgroundFetchResultNewData); } - (void)saveLocation { bgTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{ [[UIApplication sharedApplication] endBackgroundTask:bgTask]; }]; char *hostname; struct hostent *hostinfo; hostname = "m.google"; hostinfo = gethostbyname(hostname); if (hostname == NULL) { NSLog(@"No internet connection (saveLocation)"); return; } if (self.locationManager.location.coordinate.latitude == 0.0 || self.locationManager.location.coordinate.longitude == 0.0) { NSLog(@"saveLocation - coordinates are 0.0."); return; } NSLog(@"saveLocation - trying to get location."); NSString *postBody = [NSString stringWithFormat:@"Lat=%@&Lon=%@&Date=%@&userID=%@&batteryLevel=%@&version=%@&accuracy=%@&address=%@", self.myInfo.lat, self.myInfo.lon, self.myInfo.date, self.myInfo.userID, self.myInfo.batteryLevel, self.myInfo.version, self.myInfo.accuracy, self.myInfo.address]; NSURL *completeURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@/saveLocation", WEB_SERVICES_URL]]; NSData *body = [postBody dataUsingEncoding:NSUTF8StringEncoding]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:completeURL]; [request setHTTPMethod:@"POST"]; [request setValue:kAPP_PASSWORD_VALUE forHTTPHeaderField:kAPP_PASSWORD_KEY]; [request setHTTPBody:body]; [request setValue:[NSString stringWithFormat:@"%d", body.length] forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; if (__iOS_7_And_Heigher) { NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil]; NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { if (error) { NSLog(@"saveLocation Error: %@", error.localizedDescription); } else { NSString *responseXML = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@" ResponseXML(saveLocation): %@", responseXML); [self cloudAcknowledge_whoSend:kPushCodeSendLocation]; } }]; [dataTask resume]; } else { [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) { if (connectionError) { NSLog(@"saveLocation Error: %@", connectionError.localizedDescription); } else { NSString *responseXML = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@" ResponseXML(saveLocation): %@", responseXML); [self cloudAcknowledge_whoSend:kPushCodeSendLocation]; } }]; } } - (void)startBackgroundTask { bgTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{ [[UIApplication sharedApplication] endBackgroundTask:bgTask]; }]; } - (void)endBackgroundTask { if (bgTask != UIBackgroundTaskInvalid) { [[UIApplication sharedApplication] endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; } }

而 [self endBackgroundTask] 在 cloudAcknowledge 函数的末尾.知道这里到底发生了什么吗?

And [self endBackgroundTask] is at the end of cloudAcknowledge function. Any idea what the hell is going on here?

有效载荷是这样的:{ aps = { "内容可用" = 1;};推码 = 12;}

推荐答案

问题已在 iOS 7.1 Beta 3 中修复.我仔细检查并确认它工作正常.

Issue have been fixed in iOS 7.1 Beta 3. I double checked and I confirm it's working just fine.
