Airprint support - Possible ?

[Neurox]

Hi Trucidare,
I've tested your code but I received this error "expected identifier or '(' before string constant" for Extern "C" declarations.
My XCode version is 3.2.5

[trucidare]

you need to put the code in a .mm file because its objc++ sorry i forget this

Now compile, but nothing happens.
I added the NSLog into various points of code to see what happens :

Code: (glbasic) [Select]

//
//  Airprint.mm
// 
//
//  Created by James on 21/07/11.
#import <UIKit/UIKit.h>

@interface AirPrintGLB : NSObject <UIPrintInteractionControllerDelegate>
@end

@implementation AirPrintGLB

- (id)init
{
self = [super init];
if (self) {
// Initialization code here.
NSLog(@"Init code");
}
return self;
}


-(int) GLBAirPrint:(const char *) imagePath
{
   NSLog(@"Inside function");
NSString *path = [[NSString alloc ]initWithCString: imagePath];
NSData *myData = [NSData dataWithContentsOfFile: path];
   NSLog(@"Img: %@ ",path);

UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
if (![UIPrintInteractionController isPrintingAvailable])
{
NSLog(@"Sorry printing not supported!");
return -1;
}

if(pic && [UIPrintInteractionController canPrintData: myData] ) {
pic.delegate = self;
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.jobName = [path lastPathComponent];
printInfo.duplex = UIPrintInfoDuplexLongEdge;
pic.printInfo = printInfo;
pic.showsPageRange = YES;
pic.printingItem = myData;

void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) = ^(UIPrintInteractionController *pic, BOOL completed, NSError *error) {
if (!completed && error) {
NSLog(@"Error accoured!");
} else {
NSLog(@"Tadaaaa");
}
};
[pic presentAnimated:YES completionHandler:completionHandler];

} else {
NSLog(@"Error with myData");
     return 0;
}
   NSLog(@"Out from function");
return 1;
}
@end

extern "C" int GLBAirPrint(const char* file);
extern "C" int GLBAirPrint(const char* file) {
AirPrintGLB *printInfo = [[AirPrintGLB alloc]init];
    return [printInfo GLBAirPrint:file];
}

This is result from debugger console :

[trucidare]

cant say - on simulator it works fine, i tested with a gif file. i think i enable airprint via hack and test on real device

I'm crazy out.
I've made test and test and test
but the app don't print to my HP printer and not appear the window of configuration airprint
