Examples of C++/Objective-C interop

Posted by | Objective C, QT |

From QT’s Purchasing:

//SKProductsRequestDelegate
-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    NSArray<SKProduct *> *products = response.products;
    SKProduct *product = [products count] == 1 ? [[products firstObject] retain] : nil;

    if (product == nil) {
        //Invalid product ID
        NSString *invalidId = [response.invalidProductIdentifiers firstObject];
        QMetaObject::invokeMethod(backend, "registerQueryFailure", Qt::AutoConnection, Q_ARG(QString, QString::fromNSString(invalidId)));
    } else {
        //Valid product query
        //Create a IosInAppPurchaseProduct
        IosInAppPurchaseProduct *validProduct = new IosInAppPurchaseProduct(product, backend->productTypeForProductId(QString::fromNSString([product productIdentifier])));
        if (validProduct->thread() != backend->thread()) {
            validProduct->moveToThread(backend->thread());
            QMetaObject::invokeMethod(backend, "setParentToBackend", Qt::AutoConnection, Q_ARG(QObject*, validProduct));
        }
        QMetaObject::invokeMethod(backend, "registerProduct", Qt::AutoConnection, Q_ARG(IosInAppPurchaseProduct*, validProduct));
    }

    [request release];
}

Application folder does not exist when MacOS app is run the first time

Posted by | Mac OS X |

When my QT app starts first time on MacOS, its directory ./Application Support/Sharlines/Lines/ does not exit, but QT creates it when I write to QSettings first time.

To create the local directory I added the following code:

// Local data directory does not exist when the app is run first time on MacOS.
if (fs::create_directories(GetLocalFolder()))
{
    qDebug() << static_cast<QString>(qtil::Format() << "Local folder '" << GetLocalFolder() << "' has been created.");
}

Posted by | Apple App Store, Google Play |

First I created a PHP file lines-app-store.php on sharlines.com website with the following content:

<?php

$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");

$Android= stripos($_SERVER['HTTP_USER_AGENT'],"Android");

//check if user is using ipod, iphone or ipad...
if( $iPod || $iPhone || $iPad || $macOs)
{
        //we send these people to Apple Store
        header('Location: https://apps.apple.com/app/id6504194961');

Using Swift in a QT6 app

Posted by | QT, Swift |

I simply opened arboreus_examples/qt6/CMake/UsingSwift/UsingSwift_v3/CMakeLists.txt in QT Creator and was able to build it and run.

In its main.cpp it creates a Swift wrapper and calls method:

ASwift* oSwift = new ASwift(&oEngine);
oSwift->mInit();
_A_DEBUG << oSwift->mString();

My first attempt to build Yandex Mobile Ads Example for iOS

Posted by | iOS | Tagged |

According to the official repository docs I tried to install CocaPods:

 sudo gem install cocoapods

but got the following error:

ERROR:  Error installing cocoapods:
        The last version of drb (>= 0) to support your Ruby & RubyGems was 2.0.6. Try installing it with `gem install drb -v 2.0.6` and then running the current command again
        drb requires Ruby version >= 2.7.0. The current ruby version is 2.6.10.210.

Installed some dependencies and the installation of CocoaPods succeeded:

sudo gem install drb -v 2.0.6
sudo gem install activesupport -v 6.1.7.8
sudo gem install cocoapods
