Swift 保存pdf并在webview显示

概述本例中服务器返回的是base64 字符串，也可以直接返回byte[]，看server接口的定义 let nsData = NSData(base64Encoded: data!!) 拿到nsData以后，把pdf写到device let theData = ServiceProxy().CallGetPayslipFile(recordId: payslip.recordId)//"204586" 本例中服务器返回的是base64 字符串，也可以直接返回byte[]，看server接口的定义

let nsData = NSData(base64Encoded: data!!)

拿到nsData以后，把pdf写到device

let theData = ServiceProxy().CallGetPayslipfile(recordID: payslip.recordID)//"204586"        var docURL = (fileManager.default.urls(for: .documentDirectory,in: .userDomainMask)).last as NSURL?                docURL = docURL?.appendingPathComponent( "myPayslip.pdf")! as NSURL?                //Lastly,write your file to the disk.        theData.write(to: docURL! as URL,atomically: true)

使用webvIEw显示pdf

func loadpdf(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)    }
