OC与js的交互

js端

function displaymessage() {
var u = navigator.userAgent, app = navigator.appVersion;
var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1;
var isIOS = !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/);
if(isAndroid){
Android.changeActivity("成功");
}
if(isIOS){
window.webkit.messageHandlers.submitResult.postMessage("成功");
}
}

iOS客户端

CGRectwebFrame =CGRectMake(0.0,0.0,kScreenWidth,kScreenHeight-8.0);
WKWebView*wkWebView = [[WKWebViewalloc]initWithFrame:webFrameconfiguration:self.configuration];
wkWebView.autoresizingMask=UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
wkWebView.backgroundColor= [UIColorwhiteColor];
wkWebView.navigationDelegate=self;
wkWebView.UIDelegate=self;
[self.viewinsertSubview:wkWebViewbelowSubview:progressView];

• (void)userContentController:(WKUserContentController)userContentController didReceiveScriptMessage:(WKScriptMessage)message {
  if([message.nameisEqualToString:@"submitResult"]) {
  if([message.bodyisEqualToString:@"成功"]) {
  [self.navigationControllerpopViewControllerAnimated:YES];
  }else{
  }
  //[self showMsg:message.body];
  }
  }
