Function that sends an image to AirPrint - objective-c

Question

Im trying to find a function that lets me print using AirPrint.
I have a button btnPrint, that when pressed, should print myPic.jpg to the default AirPrint device. But I cannot figure out if there even is such a function.
I cannot find a lot of documentation on AirPrint in xcode.

Apple has documentation on printing that would probably benefit you.
And the following is from Objective-C code for AirPrint:
Check wether printing is available:
if ([UIPrintInteractionController isPrintingAvailable])
{
// Available
} else {
// Not Available
}
Print after button click:
-(IBAction) buttonClicked: (id) sender;
{
NSMutableString *printBody = [NSMutableString stringWithFormat:#"%#, %#",self.encoded.text, self.decoded.text];
[printBody appendFormat:#"\n\n\n\nPrinted From *myapp*"];
UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
pic.delegate = self;
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.jobName = self.titleLabel.text;
pic.printInfo = printInfo;
UISimpleTextPrintFormatter *textFormatter = [[UISimpleTextPrintFormatter alloc] initWithText:printBody];
textFormatter.startPage = 0;
textFormatter.contentInsets = UIEdgeInsetsMake(72.0, 72.0, 72.0, 72.0); // 1 inch margins
textFormatter.maximumContentWidth = 6 * 72.0;
pic.printFormatter = textFormatter;
[textFormatter release];
pic.showsPageRange = YES;
void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) =
^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {
if (!completed && error) {
NSLog(#"Printing could not complete because of error: %#", error);
}
};
[pic presentFromBarButtonItem:self.rightButton animated:YES completionHandler:completionHandler];
}
