I've a very strange problem, I implemented:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler
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.
My code below:
- (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 = "http://m.google.com";
hostinfo = gethostbyname(hostname);
if (hostname == NULL) {

NSURL *completeURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@/saveLocation", WEB_SERVICES_URL]];
NSData *body = [postBody dataUsingEncoding:NSUTF8StringEncoding];

[request setHTTPMethod:@"POST"];
[request setValue:kAPP_PASSWORD_VALUE forHTTPHeaderField:kAPP_PASSWORD_KEY];
[request setHTTPBody:body];

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(@"\n\nResponseXML(saveLocation):\n%@", 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(@"\n\nResponseXML(saveLocation):\n%@", 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;
}
}
And [self endBackgroundTask] is at the end of cloudAcknowledge function.
Any idea what the hell is going on here?
EDIT:
Payload goes like this:
{ aps = { "content-available" = 1; }; pushCode = 12; }
