如何在Airift中将Airprint方向设置为Landscape？

Question

I have to send an Airprint my WebView in landscape mode. But I am getting error while setting up my orientation. I have written this code

    let printcontroller = UIPrintInteractionController.sharedPrintController()
    let printinfo = UIPrintInfo(dictionary:nil)
    printinfo.jobName = "Printing Label"
    printinfo.outputType = UIPrintInfoOutputType.General
    printcontroller.printInfo = printinfo
    printinfo.orientation = UIDeviceOrientationLandscapeRight
    printcontroller.printFormatter = myWeb.viewPrintFormatter()
    printcontroller.showsNumberOfCopies = false
    printcontroller.presentAnimated(true) { (_, isPrinted, error) in
        if error == nil
        {
            if isPrinted
            {
                print ("Printed Successfully")
            }   else
            {
                print ("Printing failed")
            }

        }
    }
    self.performSegueWithIdentifier("finaltohome", sender: nil)

Please help me.

Answer 1

It's enums now: UIDeviceOrientation.LandscapeLeft or UIDeviceOrientation.LandscapeRight . And you need to import UIKit .

Answer 2

UIPrintInfo有自己的方向枚举UIPrintInfoOrientation ，它有两个值，纵向或横向。

printinfo.orientation = UIPrintInfoOrientation.landscape

Answer 3

I use the following:

`let printInfo = UIPrintInfo(dictionary:nil)
 printInfo.outputType = UIPrintInfoOutputType.general
 printInfo.jobName = "print Job"
 printInfo.orientation = .landscape
 printController.printInfo = printInfo`
