Swift之实践（5）
代码,粘贴过去即可
1.选中工程,点击右键,New File&在iOS下选中Othe&Empty,生成一个.js的脚本文件,将代码粘贴过去保存;
var script = document.createElement('script');
script.type = 'text/javascript';
script.text = '
function signin_go(){
location.href="ios:@signin_go";
document.getElementsByTagName('head')[0].appendChild(script);
2.实现过程;
import UIKit
class ViewController: UIViewController,UIWebViewDelegate {
@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
webView.loadRequest(NSURLRequest(URL: NSURL(string: "/user/signin")!))
webView.delegate = self
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -& Bool{
let rurl =
request.URL?.absoluteString
if (rurl!.hasPrefix("ios:")){
let method =
rurl!.componentsSeparatedByString("@")[1]
if method == "signin_go"{
signin_go()
return false
return true
func webViewDidFinishLoad(webView: UIWebView){
let jsPath =
NSBundle.mainBundle().pathForResource("app", ofType: "js")
var jsString :String = try! String(contentsOfFile: jsPath!, encoding: 4)
jsString = jsString.stringByReplacingOccurrencesOfString("\n", withString: "")
webView.stringByEvaluatingJavaScriptFromString(jsString as String)
func signin_go(){
NSLog("JS 调用了OC中的signin_go方法")
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
3.点击网页中登录按钮,会调用OC中的signin_go方法;
参考原著出现的错误
1.参考原著的时候,会提示以下错误;
解决方法: 在前面加上try! ;
var jsString :String = try! String(contentsOfFile: jsPath!, encoding: 4)
2.encoding为0时,会提示以下错误信息,原因是编码格式错误;
2016-03-01 13:21:31.860 Swift_UIWebView[2292:905421] Incorrect NSStringEncoding value 0x0000 detected. Assuming NSASCIIStringEncoding. Will stop this compatiblity mapping behavior in the near future.
解决方法:将encoding值设置为4,设置UTF8的编码格式即可;
