La impresión de PDF utilizando AirPrint causa una producción pequeña

Question

UIPrintInteractionController imprimir un pdf con UIPrintInteractionController que carga en UIWevView . La buena noticia es que puedo imprimir lo malo es que el resultado de la impresión es demasiado pequeño.

any help would be appreciated :)
- (IBACTION) printPDF {
if ((!_webView)) return;
UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];
void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) =
^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {
if(!completed && error){
NSLog(@"FAILED! due to error in domain %@ with error code %ld",
error.domain, (long)error.code);
}
};
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.duplex = UIPrintInfoDuplexLongEdge;
controller.printInfo = printInfo;
controller.showsPageRange = YES;
_webView.scalesPageToFit = NO;
UIViewPrintFormatter *viewFormatter = [_webView viewPrintFormatter];
viewFormatter.startPage = 0;
controller.printFormatter = viewFormatter;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
/* [controller presentFromBarButtonItem:printButton animated:YES completionHandler:completionHandler]; */
}else
[controller presentAnimated:YES completionHandler:completionHandler];
}

La salida:

Answer 1

Si encuentra la solución, evite imprimir el formulario IUWebView . Descargo directamente el PDF en formato NSData .

_data represente el NSData que descargo por solicitud.

 if (_data) {
UIPrintInteractionController *printController = [UIPrintInteractionController sharedPrintController];
printController.delegate = self;
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
//printInfo.jobName = [path lastPathComponent];
printInfo.duplex = UIPrintInfoDuplexLongEdge;
printController.printInfo = printInfo;
printController.showsPageRange = YES;
printController.printingItem = _data;
void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) = ^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {
if (!completed && error) {
NSLog(@"FAILED! due to error in domain %@ with error code %lu", error.domain, (long)error.code);
}
};
[printController presentAnimated:YES completionHandler:completionHandler];
}

prueba con esta paz de código ...

-(IBAction)printPDF
{
_webView.scalesPageToFit=YES;
UIImage *img=[self imageWithView:_webView];
UIPrintInteractionController *pic = [UIPrintInteractionController
sharedPrintController];
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.duplex = UIPrintInfoDuplexLongEdge;
pic.printInfo = printInfo;
pic.showsPageRange = YES;
pic.printingItem = img;
pic.showsPageRange = YES;
UIPrintInteractionCompletionHandler completionHandler =
^(UIPrintInteractionController *printController, BOOL completed,
NSError *error) {
if(!completed && error)
{
NSLog(@"Print failed - domain: %@ error code %u", error.domain,
error.code);
}
};

}

Además de la respuesta de @crescendolls, aquí hay una pieza completa de código para convertir PDF en su vista web a datos, e imprimirlo en consecuencia.

-(void)printReport {
UIPrintInfo *pi = [UIPrintInfo printInfo];
pi.outputType = UIPrintInfoOutputGeneral;
pi.jobName = webView.request.URL.absoluteString;
pi.orientation = UIPrintInfoOrientationPortrait;
pi.duplex = UIPrintInfoDuplexLongEdge;
UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
pic.printInfo = pi;
pic.showsPageRange = YES;
//does not display PDF appropriately
//pic.printFormatter = webView.viewPrintFormatter;
//does display PDF appropriately
NSCachedURLResponse* webResponse = [[NSURLCache sharedURLCache] cachedResponseForRequest:[webView request]];
NSData* webData = [webResponse data];
pic.printingItem = webData;
[pic presentFromBarButtonItem:self.printBarButton animated:YES completionHandler:^(UIPrintInteractionController *pic2, BOOL completed, NSError *error) {
// indicate done or error
}];
}
