Apple

The problem is that I have no indications about the crash even setting an “All Exceptions” breakpoint. So I’m unable to identify the real case of this crash. The “computation flow” ends in "class AppDelegate: UIResponder, UIApplicationDelegate” without leave any information. I’ve noticed also that tis anomaly is present only on iPad device and iPad simulator. On iPhone device/simulator all works fine.

1. Could you please post the stack trace and the reason for the crash?

2. If this is an unhandled exception then the exception details would be helpful to include as well.

3. What is the value of self.testo.text that causes the crash?

Hi All.
In my app I’ve a method used to print some text on a printer.

My code is

let printController = UIPrintInteractionController.sharedPrintController()

let printInfo = UIPrintInfo(dictionary:nil)
printInfo.outputType = UIPrintInfoOutputType.General
printInfo.jobName = "note"
printController.printInfo = printInfo

func textFormatter(text: String) -> String
{
return text.stringByReplacingOccurrencesOfString("\n", withString: "<BR>")
}

let formatter = UIMarkupTextPrintFormatter(markupText: textFormatter(self.testo.text))
formatter.contentInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
printController.printFormatter = formatter

if UIDevice.currentDevice().userInterfaceIdiom == .Pad
{
printController.presentFromRect(self.printBtn.frame, inView:self.view, animated:true, completionHandler: nil)
}
else
{
printController.presentAnimated(true, completionHandler: nil)
}

This code works properly in iOS 8.3 but my app crash in iOS 9.3 when in the code above I call

printController.presentFromRect(self.printBtn.frame, inView:self.view, animated:true, completionHandler: nil)

I’ve noticed that the app doesn’t crash if the self.testo.text is an empty string. This behaviour is the same on the simulator and on a real device.

Where is my mistake? Any Idea?

Regards

Luca.
