将值从iOS本机代码传递给cordova

mug*_*tsu 7 plugins ios cordova

我有一些从我的本机代码生成的值,我想传递给phonegap.这些数据是实时生成的,并不直接受用户通过phonegap gui操作的影响.我的本机代码是我制作的插件的一部分.

解决这个问题的最佳方法是什么?我希望有一个函数可以随时发送数据,并在cordova端有一个监听器.我正在使用Cordova 1.5和Xcode 4.3.

这是我到目前为止:

swipe.js:

var swipe={
     callNativeFunction: function (success, fail, resultType) {
    return Cordova.exec( success, fail, 
                        "ca.swipe", 
                        "nativeFunction", 
                        [resultType]); }

};

index.html的:

...

function callNativePlugin( returnSuccess ) {
            swipe.callNativeFunction( nativePluginResultHandler, nativePluginErrorHandler, returnSuccess );
        }

        function nativePluginResultHandler (result) {
            alert("SUCCESS: \r\n"+result );
        }

        function nativePluginErrorHandler (error) {
            alert("ERROR: \r\n"+error );
        } ...  <body onload="onBodyLoad()">     <h1>Hey, it's Cordova!</h1>

      <button onclick="callNativePlugin('success');">Success</button>
      <button onclick="callNativePlugin('error');">Fail</button>

  </body> ...

我现在的代码没有什么可以做我想要的.我不确定如何在cordova和native中设置代码.

听起来你需要能够从目标 C 与 PhoneGap 对话,在这种情况下你应该能够使用类似的东西:

 NSString *jsResult = [theWebView stringByEvaluatingJavaScriptFromString:@"hello()"];
 NSLog(@"jsResult=%@",jsResult);

如果你的index.html中有一个像“hello”这样的JS函数,如下所示:

function hello(){return "hello";}
