Swift 3 打印功能

概述1. 加载到webview再打印 2. 直接打印nsdata func printViaWebView(fileName: String){ let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] let filePath = "\

1. 加载到webvIEw再打印

2. 直接打印nsdata

func printViaWebVIEw(filename: String){ let documentsPath = NSSearchPathForDirectorIEsInDomains(.documentDirectory,.userDomainMask,true)[0]        let filePath = "\(documentsPath)/\(filename)"        let url = NSURL(fileURLWithPath: filePath)        let urlRequest = NSURLRequest(url: url as URL)                webVIEw.loadRequest(urlRequest as URLRequest)                        let pic = UIPrintInteractionController.shared        let printInfo : uiprintinfo = uiprintinfo(dictionary: nil)                printInfo.outputType = uiprintinfoOutputType.general        printInfo.jobname = url.absoluteString!                pic.printInfo = printInfo        pic.printFormatter = webVIEw.vIEwPrintFormatter()        pic.showsPageRange = false                pic.present(animated: true,completionHandler: nil)}func printViaNSData(filename: String){let documentsPath = NSSearchPathForDirectorIEsInDomains(.documentDirectory,true)[0]        let filePath = "\(documentsPath)/\(filename)"        let url = NSURL(fileURLWithPath: filePath)        let urlRequest = NSURLRequest(url: url as URL)                webVIEw.loadRequest(urlRequest as URLRequest)                        let pic = UIPrintInteractionController.shared        let printInfo : uiprintinfo = uiprintinfo(dictionary: nil)                printInfo.outputType = uiprintinfoOutputType.general        //printInfo.jobname = url.absoluteString!        //printInfo.orIEntation = .portrait                pic.printingItem = NSData(contentsOffile: filePath)        pic.showsPaperSelectionForLoadedPapers = true;        pic.showsPageRange = true;        pic.showsNumberOfcopIEs = true;        pic.printInfo = printInfo        //pic.printFormatter = webVIEw.vIEwPrintFormatter()                pic.present(animated: true,completionHandler: nil)}
