IOS - qiosapplicationdelegate.h linking problem in QtCreator



  • Hello,

    I would like to use QIOSApplicationDelegate in my own AppDelegate.m

    I'm using Qt Creator to make project. And it doesn't find the type QIOSApplicationDelegate.

    I know it comes from qtbase/src/platforms/ios/qiosapplicationdelegate.h, but I don't find it in Qt5.5.1/5.5/ios/include folder.

    Do you have an idea how to use this type in my project ?

    Thanks for your help



  • The header is missing because it's not intended to be used by developers. As we have no other way to extend the default application delegate, my workaround was to copy its definition in my project and extend it using a category. It works nicely.

    myapplicationdelegate.h

    #import <UIKit/UIKit.h>
    
    @interface QIOSApplicationDelegate : UIResponder <UIApplicationDelegate>
    @end
    
    @interface QIOSApplicationDelegate (MyApplicationDelegate)
    	- (void) someMethod;
    @end
    

    myapplicationdelegate.m

    #include "myapplicationdelegate.h"
    
    @implementation QIOSApplicationDelegate (MyApplicationDelegate)
    
    -(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    	//
    }
    - (void) someMethod {
    	//
    }
    
    @end


  • It's working fine.
    Thank you a lot



  • Be careful when overriding the following method:

    - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
    

    This is the only one implemented by QIOSApplicationDelegate, so make sure you call the base implementation using "super".



  • Thanks for the advise.

    I'm trying to include Google Cloud Messaging, but I don't know where to put properties from AppDelegate interface.
    If I follow the example there . I get some build errors :

    MyAppDelegate.m:21: error : use of undeclared identifier '_registrationKey'
    _registrationKey = @"onRegistrationCompleted";
    

    There is the code :

    MyAppDelegate.h

    #import <ios/Pods/Google/Headers/GGLCloudMessaging/Public/CloudMessaging.h>
    #import <UIKit/UIKit.h>
    
    @interface QIOSApplicationDelegate : UIResponder <UIApplicationDelegate, GGLInstanceIDDelegate, GCMReceiverDelegate>
    @end
    
    @interface QIOSApplicationDelegate (MyAppDelegate)
    @property(nonatomic, strong) UIWindow *window;
    @property(nonatomic, readonly, strong) NSString *registrationKey;
    @property(nonatomic, readonly, strong) NSString *messageKey;
    @property(nonatomic, readonly, strong) NSString *gcmSenderID;
    @property(nonatomic, readonly, strong) NSDictionary *registrationOptions;
    @end
    

    MyAppDelegate.m

    #include "MyAppDelegate.h"
    
    @interface QIOSApplicationDelegate (MyAppDelegate)
    @property(nonatomic, strong) void (^registrationHandler)(NSString *registrationToken, NSError *error);
    @property(nonatomic, assign) BOOL connectedToGCM;
    @property(nonatomic, strong) NSString* registrationToken;
    @property(nonatomic, assign) BOOL subscribedToTopic;
    @end
    
    @implementation QIOSApplicationDelegate (MyAppDelegate)
    
    // [START register_for_remote_notifications]
    - (BOOL)application:(UIApplication *)application
          didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
      // [START_EXCLUDE]
      _registrationKey = @"onRegistrationCompleted";
      _messageKey = @"onMessageReceived";
      ..................
    

    Do you have an idea ?



  • Properties on categories can't be synthesized automatically. You have to provide the get and set methods yourself. Please, take a look at:

    http://stackoverflow.com/a/14899909/4681095



  • Thx, now it looks like the builder is ok with this way of synthesizing.
    But the linker has some problems, because it may missing a link flag ? There is the trace :

  • Google Cloud Messaging requires the sqlite library. Add -lsqlite3 to your linker flags.



  • QMAKE_LFLAGS += -lsqlite3

    Uhuh :) it worked for _sqlite3 links, but there is still _OBJC_CLASS link.

    QMAKE_LFLAGS += -lsqlite3 -ObjC
    

    Then I tried with -ObjC. But I got an other error :
    Undefined symbols for architecture arm64:
    "_ABMultiValueReplaceLabelAtIndex", referenced from:
    -[GSDK_GTMABMutableMultiValue replaceLabelAtIndex:withLabel:] in libGTM_AddressBook.a(GTMABAddressBook.o)
    "_ABMultiValueGetPropertyType", referenced from:
    -[GSDK_GTMABMultiValue propertyType] in libGTM_AddressBook.a(GTMABAddressBook.o)
    ...

    QMAKE_LFLAGS += -lsqlite3 -ObjC -framework
    

    I added -framework. An other error :
    ld: framework not found -stdlib=libc++

    QMAKE_LFLAGS += -lsqlite3 -ObjC -framework -stdlib=libstdc++
    

    With -stdlib=libstdc++, the error is :
    ld: framework not found -stdlib=libstdc++



  • It's woking with those linker options :

    QMAKE_LFLAGS += -ObjC -lsqlite3 -lz -framework "AddressBook" -framework "AssetsLibrary" -framework "CoreFoundation" -framework "CoreGraphics" -framework "CoreLocation" -framework "CoreMotion" -framework "MessageUI" -framework "SystemConfiguration"
    

    Thx again, Leonardo. I'm nearer from the Notification Push system.



  • If you're just interested in receiving push notifications, I think the InstanceID library would be enough.

    I have a bug about including GoogleService-Info.plist, I'm not sure about the right way to do.
    In the .pro file, I have this :

    QMAKE_BUNDLE_DATA += ios/GoogleService-Info.plist
    QMAKE_INFO_PLIST = ios/Info.plist
    

    The GoogleService-Info.plist should be ok, I already tested it in the example project of Google.
    There is this error during execution :

  • I mean you don't need to have the GCM service and library. I couldn't test it yet, but I have a similar app, and their guide for iOS suggests that once you have a registration token, you're ready to receive push notifications.

    https://developers.google.com/cloud-messaging/ios/client#receive_messages_through_the_gcm_apns_interface

    Maybe you should give it a try and test it for us. I think that the GCM library is useful for sending and receiving real time messages, like in messaging apps. But other than that, if your application is not in foreground, Google is forced to use the same push delivery system any of us would have to use. And for that the token is enough. No need for a GCM service or GoogleService-Info.plist. Here are the flags I'm using:

    -ObjC -framework AddressBook -lGGLInstanceIDLib -lGTM_iPhone -lGTM_core -lGTM_UIFont+LineHeight -lGTM_SystemVersion -lGTM_StringEncoding -lGTM_RoundedRectPath -lGTM_Regex -lGTM_NSStringXML -lGTM_NSStringHTML -lGTM_NSScannerJSON -lGTM_NSDictionary+URLArguments -lGTM_NSData+zlib -lGTM_KVO -lGTM_GTMURLBuilder -lGTM_DebugUtils -lGTM_AddressBook -lGTMStackTrace -lGTMSessionFetcher_full -lGTMSessionFetcher_core -lGSDK_Overload

    Using these libraries:

    GGLInstanceID, GoogleNetworkingUtilities, GoogleUtilities, GoogleSymbolUtilities



  • Thx, I'm going to try that. Sounds good idea.



  • I've tried something, but I have a bug during the execution of didRegisterForRemoteNotificationsWithDeviceToken function :

    -[QIOSApplicationDelegate gcmSenderID]: unrecognized selector sent to instance 0x13e524860
    *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[QIOSApplicationDelegate gcmSenderID]: unrecognized selector sent to instance 0x13e524860'
    

    There is the function :

        self.gcmSenderID = @"MYSENDERID";
        [[GGLInstanceID sharedInstance] tokenWithAuthorizedEntity:self.gcmSenderID scope:kGGLInstanceIDScopeGCM options:self.registrationOptions handler:self.registrationHandler];
    }
    

    There is the didFinishLaunchingWithOptions function :

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
        self.registrationKey = @"onRegistrationCompleted";
        self.gcmSenderID = @"MYSENDERID";
    
        // Register for remote notifications
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1) { // iOS 7.1 or earlier
            UIRemoteNotificationType allNotificationTypes = (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge);
            [application registerForRemoteNotificationTypes:allNotificationTypes];
        } else { // iOS 8 or later
            UIUserNotificationType allNotificationTypes = (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
            UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        }
        
        
        __weak typeof(self) weakSelf = self;
    
        // Handler for registration token request
        self.registrationHandler = ^(NSString *registrationToken, NSError *error) {
            if (registrationToken != nil) {
                weakSelf.registrationToken = registrationToken;
                NSLog(@"Registration Token: %@", registrationToken);
                //[weakSelf subscribeToTopic];
                NSDictionary *userInfo = @{@"registrationToken":registrationToken};
                [[NSNotificationCenter defaultCenter] postNotificationName:weakSelf.registrationKey object:nil userInfo:userInfo];
            } else {
                NSLog(@"Registration to GCM failed with error: %@", error.localizedDescription);
                NSDictionary *userInfo = @{@"error":error.localizedDescription};
                [[NSNotificationCenter defaultCenter] postNotificationName:weakSelf.registrationKey object:nil userInfo:userInfo];
            }
        };
        return YES;
    }


  • According to this stackoverflow post, I should use the gstatic version of GCM.
    I don't have an iphone for testing now, I'll test tonight.



  • I tried without GCM service or GoogleService-Info.plist, but i haven't good results.

    Then I came back to GoogleService-Info.plist loading problem.
    Before I got this error :
    Could not locate configuration file: 'GoogleService-Info.plist'.
    But now, I have a better error :
    The configuration file is not a dictionary: 'GoogleService-Info.plist'.
    It looks better, isn't it ? :D .. but it still doesn't work

    There is the fix in .pro file :

    GInfo.files = ios/GoogleService-Info.plist
    GInfo.path = GoogleService-Info.plist
    
    QMAKE_BUNDLE_DATA += GInfo


  • I don't get your code. I can compile successfully without GCM service. Here's a simplified version of my code:

    -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    	GGLInstanceIDConfig* idConfig = [GGLInstanceIDConfig defaultConfig];
    	
    	idConfig.delegate = self;
    	
    	[[GGLInstanceID sharedInstance] startWithConfig:idConfig];
    	
    	//====================================
    	
    	if([application respondsToSelector:@selector(registerForRemoteNotifications)]){
    		[application registerForRemoteNotifications];
    	}else{
    		[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert];
    	}
    	
    	return YES;
    	
    }
    
    -(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    
    	GGLInstanceID* idInstance = [GGLInstanceID sharedInstance];
    
    	[idInstance tokenWithAuthorizedEntity:@"123456789"
    									scope:kGGLInstanceIDScopeGCM
    								  options:@{kGGLInstanceIDRegisterAPNSOption : deviceToken, kGGLInstanceIDAPNSServerTypeSandboxOption : @0}
    								  handler:^(NSString *token, NSError *error) {
    
    									  if(token != nil){
    
    										  // 
    
    									  }
    
    								  }];
    
    }


  • Thx to share your code.
    It's simpler than the Google sample.

    I'm just wondering what is the difference between putting startWithConfig in didFinishLaunchingWithOptions as you did, or put it in didRegisterForRemoteNotificationsWithDeviceToken as it's done in Google sample ?

    I guess it's working, I just have this error, because I'm working on simulator :
    Registration for remote notification failed with error: REMOTE_NOTIFICATION_SIMULATOR_NOT_SUPPORTED_NSERROR_DESCRIPTION

    I wait the device to make the final test.



  • Hello Leonardo,

    Now GCM service is working fine for 2 ouf of 3 cases :

    • When the app is active -> OK

    • When the app is in background, then I click on the notif popup (in IOS UI), then the app comes back -> OK

    • But for the last case, there is a bug :
      The app is closed. Then a notif popup is comming (in IOS UI), but when I click on it -> The app isn't shown back. The phone is almost blocked. It looks like the app is running in background but with a blackscreen. I don't even know how to have a log trace, because the app was previously closed manually.

    I hope you can help me again. Any way, I'm reaching the end through your help.



  • Hi. Soon I'll be performing some tests on a real device also. I'll let you know about my results.



  • Ok, then I'm waiting your test.
    I found that we can launch a qt project from xcode. With this method, I may have a better log trace (specially when the first execution is killed). I will have a look on that.



  • Hi. It worked in all three cases for me. The only time I could reproduce the issue you mentioned was when I launched the app from XCode and then closed it manually on the device. An error was thrown on XCode and the app was like suspended. In that case indeed it felt like the device was frozen, but it was so just because XCode was holding the app.



  • Thanks for your test.
    You are right, I closed manually the app. I didn't know that xcode or qt holds the app.
    Now everything looks great. I just need to check if the third case code is working, I have something like that :

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    if (launchOptions != nil) {
        NSDictionary* notif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        if (notif) {
            NSString* type_n = [notif valueForKey:@"gcm.notification.type"];
            if (type_n) {
                std::string* type = new std::string([type_n UTF8String]);
                MyNotif::setExtraType(type);
            }
        }
    }
    ...
    }


  • Hi. I don't think you need to check for the notification type, because there will be no other one. Anyway, be careful, because didFinishLaunchingWithOptions will run before your main() from Qt. It means that even QApplication won't be available by then.
