ios - 如何快速将 Airprint 方向设置为横向？

Question

我必须在横向模式下向我的 WebView 发送 Airprint。但是我在设置方向时遇到错误。我写了这段代码

    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)

请帮帮我。

现在是枚举:UIDeviceOrientation.LandscapeLeft 或 UIDeviceOrientation.LandscapeRight。并且您需要导入 UIKit。
