[Solved]Printing on iOS

[patrikd]

For all those who also need this functionality:
[pic presentFromRect:view.bounds inView:view Animated:YES completionHandler:....
it's animated
that was the whole problem. Thx to the guys from digia!

Hi all,
i'm currently stucked on printing with airprint. So far I can initialize all needed data. Problem is that
I don't have a UIButton or something similar to pass it to the UIPrintInteractionController. So I tried
to pass the main view but this ends up in an exception telling: "unrecoginized selector sent to instance".
Has anyone experience with this, or an other idea? I couldn't find a way to send something to print without
and objective-c ui element.

void CMobilePrinter::printPage(QString pathImg){

QFile f(pathImg);
qDebug() << f.fileName();
qDebug() << f.exists();

QTemporaryFile* temp = QTemporaryFile::createNativeFile(f);
if (temp != NULL){
    qDebug() << temp->rename(temp->fileName()+ ".jpg");
    qDebug() << temp->exists();
    qDebug() << temp->fileName();
    qDebug() << temp->size();


    NSString *path = temp->fileName().toNSString();
    NSURL* imgURL = [NSURL fileURLWithPath:path];
    UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];

    qDebug() << "ios enter print";
    if  (pic && [UIPrintInteractionController canPrintURL: imgURL] ) {

        qDebug() << "ios enter print valid";
        UIPrintInfo *printInfo = [UIPrintInfo printInfo];
        printInfo.outputType = UIPrintInfoOutputGeneral;

        printInfo.jobName = @"test.jpg";
        pic.printInfo = printInfo;
        pic.printingItem = imgURL;
        QWindowList list = QGuiApplication::allWindows();
        UIView *view = static_cast<UIView *>( QGuiApplication::platformNativeInterface()->nativeResourceForWindow("uiview", list.at(0)) );
        [pic presentFromRect:view.bounds inView:view Animated:YES completionHandler:
                    ^(UIPrintInteractionController *pic, BOOL completed, NSError *error) {
                        if (!completed && error)
                             NSLog(@"FAILED! due to error in domain %@ with error code %u", error.domain, error.code);
                        else
                           NSLog(@"ok");
                   }
        ];
    }

}

thx,
patrik
