Help for Qt for iOS with AdMob implementation

[Adla]

Hi,

Can anyone please suggest an answer for my problem.

I am developing an iOS app using Qt and trying to implement AdMob.

I installed AdMob required frameworks using pod file, they are installed correctly and .xcworkspace has been successfully created.

But when I run the build .xcworkspace file in Xcode, then it is showing the errors saying It can not find these frameworks.

Is there anything I need to include in CMakeLists.txt file, please see CMakeLists.txt file.

cmake_minimum_required(VERSION 3.16)

project(testing VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)

set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 6.5 REQUIRED COMPONENTS Quick Core Widgets)

qt_standard_project_setup(REQUIRES 6.5)

qt_add_executable(apptesting
    main.cpp
    AdMobManager.m
)

# qt_add_qml_module(apptesting
#     URI testing
#     VERSION 1.0
#     QML_FILES
#         Main.qml
# )

# Qt for iOS sets MACOSX_BUNDLE_GUI_IDENTIFIER automatically since Qt 6.1.
# If you are developing for iOS or macOS you should consider setting an
# explicit, fixed bundle identifier manually though.
set_target_properties(apptesting PROPERTIES
#    MACOSX_BUNDLE_GUI_IDENTIFIER com.example.apptesting
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

target_link_libraries(apptesting PUBLIC
    Qt6::Quick
    Qt6::Core
    Qt6::Widgets
    "-framework UIKit"
    "-framework FirebaseCore"
    "-framework GoogleMobileAds"
    )
    
# Enable ARC for Objective-C++ files
set_source_files_properties(AdMobManager.mm PROPERTIES COMPILE_FLAGS "-fobjc-arc")

#set(CMAKE_XCODE_ATTRIBUTE_CLANG_ENABLE_MODULES YES)

include(GNUInstallDirs)

install(TARGETS apptesting
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

qt_generate_deploy_qml_app_script(
    TARGET apptesting
    OUTPUT_SCRIPT deploy_script
    MACOS_BUNDLE_POST_BUILD
    NO_UNSUPPORTED_PLATFORM_ERROR
    DEPLOY_USER_QML_MODULES_ON_UNSUPPORTED_PLATFORM
)

install(SCRIPT ${deploy_script})

Also I did below changes in Xcode.

• In my project's build settings:

•  Add the /usr/lib/swift path to Runpath Search Paths.
  

•  Add the -ObjC linker flag to Other Linker Flags.
  

Thanks.

Hi, Can someone please have a look at my problem.

Hi,

Intuitively I would say that you have to tell cmake where to find these framework so it can properly configure the build system.

@SGaist ,

I downloaded Google Mobile Ads manually, and I updated the CMakeLists.txt file, but still it is not working.

# Define the frameworks path
set(FRAMEWORKS_DIR "${CMAKE_SOURCE_DIR}/ios_frameworks")

# Add include directories
target_include_directories(apptesting PUBLIC
    ${FRAMEWORKS_DIR}
)

# Link the frameworks explicitly
target_link_libraries(apptesting PUBLIC
    "-framework GoogleMobileAds" 
    Qt6::Core
    Qt6::Quick
    Qt6::Widgets
)

# Link the framework search paths
set(CMAKE_EXE_LINKER_FLAGS
    "${CMAKE_EXE_LINKER_FLAGS} -F${FRAMEWORKS_DIR}"
)

or

should I consider the Google mobile ads which are in Pod in Xcode, but how can I use this location in CMakeLists.txt

Has anyone implemented AdMob on iOS using Qt ?, Are there any example projects that will give some ideas ?

[SGaist]

The folks at Felgo have a plug-in for AdMob.

@SGaist ,

Thanks. got the answer I needed.

[SGaist]

What was it ? It might other people having the same issue as you.

[Adla]

I stored in GitHub, if anyone interested, you can have a look at it. Link below.

Also, for Android link below.

Does anyone know how to implement Firebase Core and Firebase Analytics for both Android and iOS using CMakeLists.txt in Qt ?

@Adla Thank you for sharing. GoogleMobileAds.framework in your Pods.zip works well.
May I ask you how you generated this Pods.zip?
I tried to generate it but it didn't work as yours.

Here is my steps.

1. Run Xcode
2. Create an iOS app project with
   Interface: Storyboard
   Language: Objective-C
3. pod init
4. Edit Podfile
   pod 'Google-Mobile-Ads-SDK'
5. pod install --repo-update

But with the resulting GoogleMobileAds.framework, I got many errors,
Undefined symbols for architecture arm64:
