导读：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" va

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)
    }
