I'm trying to use the Facebook iOS Sharing SDK 4.1 but not getting a post off. I have an active session, but the following code does not post to my feed, and I do not get any of the callbacks either (success, error, or cancel), even though the caller is a FBSDKSharingDelegate. I have attempted to emulate the sample code in the SDK documentation but to no avail.
if ( [[FBSDKAccessToken currentAccessToken] hasGranted:#"publish_actions"] ) {
FBSDKShareLinkContent* content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = _Object.myPostServerURL;
content.contentDescription = _Object.myPostDescription;
content.contentTitle = #"New Post";
content.imageURL = _Object.coverArtServerURL;
BOOL ok = [[FBSDKShareAPI shareWithContent:content delegate:self] share];
}
I've tried with and without the "share" message wrapped around the shareWithContent; I can't tell from the documentation if it is required. Either way, no callbacks to delegate, no post. Can someone help me?
FBSDKShareLinkContent *tempContent=[[FBSDKShareLinkContent alloc] init];
tempContent.contentTitle=#"hello";
tempContent.contentDescription=#"desc";
tempContent.imageURL=[NSURL URLWithString:#"https://camo.githubusercontent.com/67212912f8d2d6a474d1af756603f7c13c837112/687474703a2f2f692e696d6775722e636f6d2f375976386d53412e676966"];
tempContent.contentURL=[NSURL URLWithString:#"https://scrumptious-facebook.parseapp.com/meals/italian/?fb_action_ids=10200411040395078&fb_action_types=fb_sample_scrumps%3Aeat"];
_shareAPI.delegate = self;
_shareAPI.shareContent = tempContent;
[_shareAPI share];
Also to use FBSDKShareAPI,You have to implement your for login and request for necessary permissions through u get FBSDKAccessToken,then only u can directly post to user feed.This is according to documentation of Facebook,If u want to show your own interface of sharing.
Currently may be your delgate may not work but might be ur app may face the issues of no access tokens and no permission issues
[[[FBSDKLoginManager alloc] init]
logInWithPublishPermissions:#[publish_actions]
handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if ([result.grantedPermissions containsObject:publish_actions]) {
[_shareAPI share];
} else {
// This would be a nice place to tell the user why publishing
// is valuable.
}
}];
//Delegate methods
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results{
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer{
}
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error{
NSLog(#"%#",error);
}
You have to make some configuration in your appdelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
return [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];}
and
- (void)applicationDidBecomeActive:(UIApplication *)application {
[FBSDKAppEvents activateApp];
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.}
Is it possible to have a WatchKit app be a controller for it's parent iOS app?
I want to have buttons on the WatchKit app that cause an action on the iPhone app, but I can't find a way to get that going. Tried sending a notification - no joy.
Tried using WKInterfaceController.openParentApplication but that doesn't work either.
Can someone point me in the right direction?
Thanks.

See example from the blog of #NatashaTheRobot:
http://natashatherobot.com/watchkit-open-ios-app-from-watch/
Here is what my handleWatchKitExtensionRequest looks like. Check the spelling of this method in your code. You didn't spell it right in the comment and that would cause a unrecognized selector crash.
-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
NSString* command = [userInfo objectForKey:#"command"];
NSString* uuid = [userInfo objectForKey:#"uuid"];
if (command == nil)
{
reply(nil);
}
else
{
if ([command isEqualToString:#"startTrip"])
{
...
//The uuid of the trip is returned to the watch app
reply(#{#"uuid": uuid});
}
else if ([command isEqualToString:#"stopTrip"])
{
...
reply(nil);
}
else if ([command isEqualToString:#"pauseTrip"])
{
...
reply(nil);
}
else if ([command isEqualToString:#"resumeTrip"])
{
...
reply(nil);
}
}
}
This is the userInfo I am getting in didReceiveRemoteNotification
aps = {
badge = 2;
sound = default;
};
u = "{\"custom\":{\"redirectlink\":\"groupdetail.html?groupid=314416&selectedtabid=5\"}}";
}
Clearly alert field is missing here. This is what I tried to make to handle missing alert :
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
NSMutableDictionary *pushDict = [NSMutableDictionary dictionaryWithDictionary:[userInfo objectForKey:#"aps"] ];
BOOL isSilentPush = [[pushDict objectForKey:#"content-available"] boolValue];
[pushDict setObject:#"You have a notification" forKey:#"alert"];
NSMutableDictionary * mut = [NSMutableDictionary dictionaryWithDictionary:userInfo]; //[userInfo copy];
[mut setObject:pushDict forKey:#"aps"];
//[mut setObject:#"5#" forKey:#"p"];
if (isSilentPush) {
NSLog(#"Silent push notification:%#", userInfo);
//load content here
// must call completionHandler
completionHandler(UIBackgroundFetchResultNewData);
}
else {
[[PushNotificationManager pushManager] handlePushReceived:mut];
// must call completionHandler
completionHandler(UIBackgroundFetchResultNoData);
}
}
But this does not generate a banner notification. Only badge, sound and alert is generated.
I know this should be handled from server side and not from iOS application, but the server guy will be back in 2 days and I have a demo to show.
Before sending a message (i.e. calling setValue on a Firebase object), is there a recommended way to determine if the user is online or offline?
For example:
[firebase setValue:someValue withCompletionBlock:^(NSError *error, Firebase *ref) {
// This block is ONLY executed if the write actually completes. But what if the user was offline when this was attempted?
// It would be nicer if the block is *always* executed, and error tells us if the write failed due to network issues.
}];
We need this in our iOS app because the user could lose connectivity if they went into a tunnel for instance. If Firebase doesn’t offer a built-in way to do this, we’ll just resort to monitoring iOS's Reachability API.
They have a section of their docs devoted to this here.
Basically observe the .info/connected ref
Firebase* connectedRef = [[Firebase alloc] initWithUrl:#"https://SampleChat.firebaseIO-demo.com/.info/connected"];
[connectedRef observeEventType:FEventTypeValue withBlock:^(FDataSnapshot *snapshot, NSString *prevName) {
if([snapshot.value boolValue]) {
// connection established (or I've reconnected after a loss of connection)
}
else {
// disconnected
}
}];
You can do something like this. Setup the observer and post notification on status change. Basically the same as accepted answer but adapted to new version of firebase framework.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
FIRDatabaseReference *ref = [[FIRDatabase database] referenceWithPath:#".info/connected"];
[ref observeEventType:FIRDataEventTypeValue withBlock:^(FIRDataSnapshot * _Nonnull snapshot) {
NSString *value = snapshot.value;
NSLog(#"Firebase connectivity status: %#", value);
self.firebaseConnected = value.boolValue;
[[NSNotificationCenter defaultCenter] postNotificationName:#".fireBaseConnectionStatus" object:nil];
}];
}
Then in any view controller of your app you can do this. Observe notifications and do something based on that (update your ui, etc).
- (void) fireBaseConnectionStatus:(NSNotification *)note
{
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[self updateButtons:app.firebaseConnected];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(fireBaseConnectionStatus:) name:#".fireBaseConnectionStatus" object:nil];
}
Hope this will help.
PS. Perhaps you will find it interesting idea to also monitor basic reachability with well known reachability.[mh] framework. Then you also could decide how do you act in case that firebase is connected on wifi or 3g.
Swift 3
let connectedRef = FIRDatabase.database().reference(withPath: ".info/connected")
connectedRef.observe(.value, with: { snapshot in
if let connected = snapshot.value as? Bool, connected {
print("Connected")
} else {
print("Not connected")
}
})

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);

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];
}

Any idea what the hell is going on here?
EDIT:
Payload goes like this:
{ aps = { "content-available" = 1; }; pushCode = 12; }
There could be number of things might have gone wrong, The first from my own experience. In order to make silent push notification work. Your payload has to be structured correctly,
{
"aps" : {
"content-available" : 1
},
"data-id" : 345
}
Does your push message has content-available: 1 if not then iOS will not call the new delegate method.
- (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
Possible reason is that Background App Refresh is off on your iPhone.
You can turn this option on/off in Settings->General->Background App Refresh.
When Background App Refresh is off on your phone, didReceiveRemoteNotification:fetchCompletionHandler method will be called only when the phone is connected to XCode.
Just want to add an updated answer.
I am facing the same problem.
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler;
Doesn't get called when the app is killed from background multitasking (double tap home button and swipe up to kill app).
I have tested this myself using development push notification and NWPusher tool (https://github.com/noodlewerk/NWPusher)
Outdated documentation
This previous block of documentation which says:
Unlike the application:didReceiveRemoteNotification: method, which is
called only when your app is running, the system calls this method
regardless of the state of your app. If your app is suspended or not
running, the system wakes up or launches your app and puts it into the
background running state before calling the method. If the user opens
your app from the system-displayed alert, the system calls this method
again so that you know which notification the user selected.
Is outdated (at the time of writing this 04/06/2015).
Updated Documentation (as at of 04/06/2015)
I checked the documentation (at the time of writing this 04/06/2015), it says:
Use this method to process incoming remote notifications for your app.
Unlike the application:didReceiveRemoteNotification: method, which is
called only when your app is running in the foreground, the system
calls this method when your app is running in the foreground or
background. In addition, if you enabled the remote notifications
background mode, the system launches your app (or wakes it from the
suspended state) and puts it in the background state when a remote
notification arrives. However, the system does not automatically
launch your app if the user has force-quit it. In that situation, the
user must relaunch your app or restart the device before the system
attempts to launch your app automatically again.
https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/index.html#//apple_ref/occ/intfm/UIApplicationDelegate/application:didReceiveRemoteNotification:fetchCompletionHandler:
If you read carefully, you'll notice it now says:
the system
calls this method when your app is running in the foreground or
background.
NOT:
regardless of the state of your app
So it looks like from iOS 8+ we're out of luck :(
TL;DR: Use Test Flight in iTunes Connect
Maybe some of you guys already figured out this, but I posting here since I don't see a clear answer.
The had the exact same problem describe. Silent push notifications worked while the Lightning cable was connected. Stopped working when I disconnected the cable. I had every NSLog and network call tracked to prove that was indeed happening.
I was using the payload suggested in many answers, as well as this one:
{
"aps" : {
"content-available": 1,
sound: ""
}
}
After many hours, I discovered that the issue is related to Adhoc and Development provisioning profiles, on iOS 8.0, 8.1 and 8.1.1. I was using Crashlytics to send beta versions of my app (that uses Adhoc profile).
The fix is:
In order to have it working, try out Apple's Test Flight integration with iTunes Connect. Using that you will send an Archive of your app (the same archive to be used on App Store) but enable your binary to be used in beta. The version installed from Test Flight probably (I can't prove) uses the same Production Provisioning Profile from the App Store, and the app works like a charm.
Here's a link that helps set up the Test Flight account:
http://code.tutsplus.com/tutorials/ios-8-beta-testing-with-testflight--cms-22224
Not even a single Silent Payload was missed.
I hope that helps someone not to lose a whole week on this issue.
This was an issue for me today and I was baffled.
iOS: 10.2.1
xCode: 8.2.1
Swift: 3.0.2
The issues was only on one phone I would get the packed only when plugged into xCode.
I re-read Apples push documentation in case I missed something with the new UserNotifications framework and or messed something up with my code to fall back to the depreciated delegate functions for iOS 9.
Anyway, I noticed this line in the documentation for application:didReceiveRemoteNotification:fetchCompletionHandler::
"Apps that use significant amounts of power when processing remote notifications may not always be woken up early to process future notifications."
It's the very last line on the page.
While I wish Apple told me more, it turns out a simple phone restart solved the problem for me. I really wish I could figure out exactly what went wrong, but here are my very speculative conclusions:
1) Push notifications were not being delivered to this app on this particular phone because of the line in the documentation mentioned above.
2) When plugged into xCode iOS is ignoring the above, documented rule.
3) I checked the (notoriously confusing) battery percentage calculator in system settings. It showed my app at a modest 6%, BUT Safari was a whopping 75% on this phone for some reason.
4) After phone restart, Safari was back down to about 25%
5) Push worked fine after that.
So... My ultimate conclusion. To weed out the documented battery issue either try a phone restart or try a different phone and see if the problem persists.
To use Background Push Download in iOS application development, here are some important points which we need to follow…
Enable UIBackgroundModes key with remote-notification value in info.plist file.
Then implement below method in your AppDelegate file.
application:didReceiveRemoteNotification:fetchCompletionHandler
More Details:ios-7-true-multitasking
Spent two days on this! Before checking your code and your push params - check that you are not on LOW POWER MODE!!!(and Background App Refresh is ON)
as you connect your device to xCode==power it will work, but if you will disconnect it - low power mode will disable background app refresh.
It is very simple. You can call your method
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler {
}
Steps:
project -->Capablities--> Background Modes
and select check boxes of "Background Fetch" & "Remote notifications", or go into .plist and select a row & give name "Background Modes" and it will create with an array, set "Item 0" with string "Remote notifications".
say to server side developer that he should send
"aps" : {
"content-available" : 1
}
thats it now you can call your methods:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler {
}
Issue have been fixed in iOS 7.1 Beta 3.
I double checked and I confirm it's working just fine.
Code that works fetching remote notifications, enable te remote notifications capability in background modes and i have background fetch enabled too (i don't know if it is necessary) I use this code:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler{
DLog(#"899- didReceiveRemoteNotification userInfo: %#",userInfo);
NSDictionary *custom=userInfo[#"custom"];
if(custom){
NSInteger code = [custom[#"code"] integerValue];
NSInteger info = [custom[#"info"] integerValue];
NSDictionary *messageInfo = userInfo[#"aps"];
[[eInfoController singleton] remoteNotificationReceived:code info:info messageInfo:messageInfo appInBackground:[UIApplication sharedApplication].applicationState==UIApplicationStateBackground];
handler(UIBackgroundFetchResultNewData);
}
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
DLog(#"899- didReceiveRemoteNotification userInfo: %#",userInfo);
NSDictionary *custom=userInfo[#"custom"];
if(custom){
NSInteger code = [custom[#"code"] integerValue];
NSInteger info = [custom[#"info"] integerValue];
NSDictionary *messageInfo = userInfo[#"aps"];
[[eInfoController singleton] remoteNotificationReceived:code info:info messageInfo:messageInfo appInBackground:[UIApplication sharedApplication].applicationState==UIApplicationStateBackground];
}
}
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
//NSLog(#"My token is: %#", deviceToken);
const unsigned *tokenBytes = (const unsigned *)[deviceToken bytes];
NSString *hexToken = [NSString stringWithFormat:#"%08x%08x%08x%08x%08x%08x%08x%08x",
ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]),
ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]),
ntohl(tokenBytes[6]), ntohl(tokenBytes[7])];
[[eInfoController singleton] setPushNotificationToken:hexToken];
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
NSLog(#"Failed to get token, error: %#", error);
}
Code that stores the notification when it background, the key for me was to start a background download task to allow me to download the information in order to store it and then when app becomes active method is triggered i check if there is a missing notification stored to show it.
-(void)remoteNotificationReceived:(NSInteger)code info:(NSInteger)info messageInfo:(NSDictionary*)messageInfo appInBackground:(BOOL)appInBackground{
DLog(#"Notification received appInBackground: %d,pushCode: %ld, messageInfo: %#",appInBackground, (long)code,messageInfo);
switch (code){
case 0:
break;
case 1:
{
NSArray *pendingAdNotifiacations=[[NSUserDefaults standardUserDefaults] objectForKey:#"pendingAdNotifiacations"];
NSMutableDictionary *addDictionary=[[NSMutableDictionary alloc] initWithDictionary:messageInfo copyItems:YES];
[addDictionary setObject:[NSNumber numberWithInteger:info] forKey:#"ad_id"];
if(!pendingAdNotifiacations){
pendingAdNotifiacations=[NSArray arrayWithObject:addDictionary];
}else{
pendingAdNotifiacations=[pendingAdNotifiacations arrayByAddingObject:addDictionary];
}
[addDictionary release];
[[NSUserDefaults standardUserDefaults] setObject:pendingAdNotifiacations forKey:#"pendingAdNotifiacations"];
[[NSUserDefaults standardUserDefaults] synchronize];
DLog(#"pendingAdNotifiacations received: %#.",pendingAdNotifiacations);

DLog(#"783- pendingAdNotifiacations: %lu.",(unsigned long)((pendingAdNotifiacations)?[pendingAdNotifiacations count]:0));
if(appInBackground){
[AdManager requestAndStoreAd:info];
}else{
[AdManager requestAndShowAd:info];
}
}
break;
default:
break;
}
}
This is the relevant code to download the info in the background using a background task:
-(void)requestAdinBackgroundMode:(NSInteger)adId{

// Do something with the result
[self endBackgroundUpdateTask];

}
}
