Use Firebase SDK on iOs (push notifications)

[Schluchti]

Hi,

has someone of you successfully used the Firebase SDK for integrating push notifications? I mostly followed this guide here: https://github.com/firebase/quickstart-ios/blob/master/messaging/MessagingExample/AppDelegate.m

The relevant parts are looking like this:

my AppDelegate:

#import "FirebaseInstanceID.h"
#import "FirebaseMessaging.h"
#import "FirebaseAnalytics.h"
#import <FIRApp.h>

@interface QIOSApplicationDelegate
@end
//add a category to QIOSApplicationDelegate
@interface QIOSApplicationDelegate (QPushNotificationDelegate)
@end

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

// Register for remote notifications. This shows a permission dialog on first run, to
        // show the dialog at a more appropriate time move this registration accordingly.
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1) {
            // iOS 7.1 or earlier. Disable the deprecation warnings.
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
            UIRemoteNotificationType allNotificationTypes =
            (UIRemoteNotificationTypeSound |
             UIRemoteNotificationTypeAlert |
             UIRemoteNotificationTypeBadge);
            [application registerForRemoteNotificationTypes:allNotificationTypes];
#pragma clang diagnostic pop
        } else {
            // iOS 8 or later
            // [START register_for_notifications]
            if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
                UIUserNotificationType allNotificationTypes =
                (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
                UIUserNotificationSettings *settings =
                [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
                [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
            }

[[UIApplication sharedApplication] registerForRemoteNotifications];
            // [END register_for_notifications]
        }
// [START configure_firebase]
    [FIRApp configure];
    // [END configure_firebase]
    // Add observer for InstanceID token refresh callback.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:)
                                                 name:kFIRInstanceIDTokenRefreshNotification object:nil];
}

my *.pro file:

MAKE_LFLAGS += -F$$PWD/ext/libraries/ios/Firebase/Analytics
    QMAKE_LFLAGS += -F$$PWD/ext/libraries/ios/Firebase/Messaging
    QMAKE_LFLAGS += -ObjC

Unfortunately I always get:

Use of undeclared identifier FIRApp

when compiling. Does anyone have an idea on how to fix that?

Hi!

V-Play Engine offers several plugins for integrating push notifications in your Qt app, for example with the Google Cloud Messaging service.
A Firebase plugin is currently being implemented and will be coming soon as well.

Best,

Here is my solution:
Create a directory "ios/CocoaPods" inside root path of the Qt Project
Create inside this directory an Xcode project "Empty" (just autogenerate a single view iOS project with Xcode and save here)
Create a file "Podfile" with the following content:
target 'Empty' do
pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'Firebase/Messaging'
pod 'Firebase/Database'
pod 'Firebase/Crash'
end

Run "pod install"; and inside the "CocoaPods" there will be a directory "Pods" with generated Frameworks.
In your .pro add the following lines to include frameworks:
LIBS += -F$$PWD/ios/CocoaPods/Pods/FirebaseCore/Frameworks -framework FirebaseCore \
-F$$PWD/ios/CocoaPods/Pods/FirebaseAnalytics/Frameworks -framework FirebaseAnalytics \
-F$$PWD/ios/CocoaPods/Pods/FirebaseAuth/Frameworks -framework FirebaseAuth \
-F$$PWD/ios/CocoaPods/Pods/FirebaseCrash/Frameworks -framework FirebaseCrash \
-F$$PWD/ios/CocoaPods/Pods/FirebaseDatabase/Frameworks -framework FirebaseDatabase \
-F$$PWD/ios/CocoaPods/Pods/FirebaseInstanceID/Frameworks -framework FirebaseInstanceID \
-F$$PWD/ios/CocoaPods/Pods/FirebaseMessaging/Frameworks -framework FirebaseMessaging

INCLUDEPATH += $$PWD/ios/CocoaPods/Pods/FirebaseCore/Frameworks/FirebaseCore.framework/Headers \
$$PWD/ios/CocoaPods/Pods/FirebaseAnalytics/Frameworks/FirebaseAnalytics.framework/Headers \
$$PWD/ios/CocoaPods/Pods/FirebaseAuth/Frameworks/FirebaseAuth.framework/Headers \
$$PWD/ios/CocoaPods/Pods/FirebaseCrash/Frameworks/FirebaseCrash.framework/Headers \
$$PWD/ios/CocoaPods/Pods/FirebaseDatabase/Frameworks/FirebaseDatabase.framework/Headers \
$$PWD/ios/CocoaPods/Pods/FirebaseInstanceID/Frameworks/FirebaseInstanceID.framework/Headers \
$$PWD/ios/CocoaPods/Pods/FirebaseMessaging/Frameworks/FirebaseMessaging.framework/Headers
XCODE_EXTRAS.files = ios/GoogleService-Info.plist
QMAKE_BUNDLE_DATA += XCODE_EXTRAS

The Zetpush https://zetpush.com/ is an option for push notifications.

Hi there,

I am currently contributing QtCloudMessaging API wrapper to Qt. Its helping developers to use push notification services in easy way. There are two services integrated: Firebase and Kaltiot embedded backends. Those two also gives example how one can extend new services behind the wrapper.

Repository is currently under preview, but has gone through multiple review rounds already and is functional. To get started do following:

1. Clone repo
   git clone https://codereview.qt-project.org/qt/qtcloudmessaging

2. Get latest patch:
   git fetch https://codereview.qt-project.org/qt/qtcloudmessaging refs/changes/55/202155/28 && git checkout FETCH_HEAD

3. Install and compile repo to your platform. Check readme instructions.
   qmake CONFIG+="firebase"
   make
   make install

4. Check example app for Firebase (detailed instructions in readme there) and embedded devices from: https://github.com/snowgrains/qtcloudmessaging-examples

4.1 The pod file install for firebase needs few tweaks for Qt-generated xcode project file, but with following commands (or added in .sh file) you can easily tweak it. Run these with terminal inside .xcodeproj folder (right click + Show Package Contents):
sed -i '' '/refType = 0;/d' ./project.pbxproj
sed -i '' '/name = "Compile Sources";/d' ./project.pbxproj
sed -i '' '/name = "Link Binary With Libraries";/d' ./project.pbxproj
sed -i '' '/name = "Copy Bundle Resources";/d' ./project.pbxproj
sed -i '' '/buildRules = (/ { N; d; }' ./project.pbxproj*

Tell me if you encounter any problems.

@SnowGrains I saw this mentioned in the blog (http://blog.qt.io/blog/2018/01/02/qt-cloud-messaging-api-available-embedded-systems/), but the URL for cloning is invalid, even just two weeks after that blog post. What happened?
