iOS讯飞语音自定义界面

MUI的人没空回答只能看他们的插件源码自己写了，废话不多说代码如下：
JS脚本 xfyun-plugin.js文件  
;define(function(require, exports, module) {  
    var _BARCODE = 'XFYunPlugin',  
        B = window.plus.bridge;  

    var XFYunPlugin =   
    {  
        /**  
         * 开始语音识别  
         */  
        startListen : function (successCallback, errorCallback)  
        {  
            var success = typeof successCallback !== 'function' ? null : function(args)   
            {  
                successCallback(args);  
            },  
            fail = typeof errorCallback !== 'function' ? null : function(code)   
            {  
                errorCallback(code);  
            };  
            callbackID = B.callbackId(success, fail);  

            return B.exec(_BARCODE, "startListen", [callbackID]);  
        },  

        /**  
         * 停止语音识别  
         */  
        stopListen : function (successCallback, errorCallback)  
        {  
            var success = typeof successCallback !== 'function' ? null : function(args)   
            {  
                successCallback(args);  
            },  
            fail = typeof errorCallback !== 'function' ? null : function(code)   
            {  
                errorCallback(code);  
            };  
            callbackID = B.callbackId(success, fail);  

            return B.exec(_BARCODE, "stopListen", [callbackID]);  
        }  
    };  
    window.plus.XFYunPlugin = XFYunPlugin;  
});
