話不多說直接上代碼

原生分享帶參數(shù)沒有返回值
js這么寫

function ThirdPartyShareImg(Path, isLine) {
    console.log("WXShareTex "+Path )
    if(cc.sys.isNative){
        if(cc.sys.OS_IOS == cc.sys.os){
            jsb.reflection.callStaticMethod("AppController","WXShareTex:IsTimeLine:",Path,isLine);
        }else{
            jsb.reflection.callStaticMethod('org/cocos2dx/javascript/AppActivity', 'WXShareTex',
                "(Ljava/lang/String;Ljava/lang/String;)V",
                Path, isLine);
        }
    }
}

iOS 這么寫

#pragma mark - ----------------- 微信分享圖片 --------------------
+(void)WXShareTex:(NSString*)content_link IsTimeLine:(NSNumber *)IsTimeLine{
    
    if (IsTimeLine.intValue == 1) {
        //1.創(chuàng)建多媒體消息結(jié)構(gòu)體
        WXMediaMessage *mediaMsg = [WXMediaMessage message];
        //2.創(chuàng)建多媒體消息中包含的圖片數(shù)據(jù)對(duì)象
        WXImageObject *imgObj = [WXImageObject object];
        //圖片真實(shí)數(shù)據(jù)
        
        NSString *imageString = content_link;
        
        if([content_link hasPrefix:@"http"])
        {//判斷字符串是否以B字符開始
            NSLog(@"開頭為字母B");
            //1.創(chuàng)建多媒體消息結(jié)構(gòu)體
            WXMediaMessage *mediaMsg = [WXMediaMessage message];
            //2.創(chuàng)建多媒體消息中包含的圖片數(shù)據(jù)對(duì)象
            WXImageObject *imgObj = [WXImageObject object];
            //圖片真實(shí)數(shù)據(jù)
            NSURL *url=[NSURL URLWithString:content_link];
            imgObj.imageData = [NSData dataWithContentsOfURL:url];
            //多媒體數(shù)據(jù)對(duì)象
            mediaMsg.mediaObject = imgObj;
            
            //3.創(chuàng)建發(fā)送消息至微信終端程序的消息結(jié)構(gòu)體
            SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
            //多媒體消息的內(nèi)容
            req.message = mediaMsg;
            //指定為發(fā)送多媒體消息（不能同時(shí)發(fā)送文本和多媒體消息，兩者只能選其一）
            req.bText = NO;
            //指定發(fā)送到會(huì)話(聊天界面)
            req.scene = WXSceneTimeline;
            //發(fā)送請(qǐng)求到微信,等待微信返回onResp
            [WXApi sendReq:req];

是不是很簡(jiǎn)單
2 沒參數(shù)有返回值
js

function ThirdPartyGetBattery() {
    var pLv = 1;
    if(cc.sys.OS_IOS == cc.sys.os){
        pLv = jsb.reflection.callStaticMethod('AppController',"GetBatteryLv");
    }else{
        pLv = jsb.reflection.callStaticMethod('org/cocos2dx/javascript/AppActivity',"GetBatteryLv","()Ljava/lang/String;");
    }
    return pLv;
}

返回值是NSNumber類型
iOS 這么寫

#pragma mark - ----------------- 電池 --------------------

+(NSNumber *)GetBatteryLv{
    
    [UIDevice currentDevice].batteryMonitoringEnabled = YES;
    double deviceLevel = [UIDevice currentDevice].batteryLevel;
    NSString *str = [NSString stringWithFormat:@"%.2f", deviceLevel];
    NSLog(@"+++++++++++++++++++++++%@", str);
    return @([str integerValue]);

}

3 沒有參數(shù)沒有返回值
JS

function ThirdPartyGetAddress() {
    console.log('ThirdPartyGetAddress 走了');
    if (cc.sys.OS_IOS == cc.sys.os) {
        jsb.reflection.callStaticMethod("AppController","getAddress");
    } else {
        jsb.reflection.callStaticMethod('org/cocos2dx/javascript/AppActivity', 'getAddress',"()V");
    }
}

iOS

#pragma mark - ----------------- 定位 --------------------
+(void)getAddress{
    
    NSLog(@"123123123");

    AMapLocationManager *locationManager = [[AMapLocationManager alloc] init];
    
    [locationManager setDelegate:self];
    
    [locationManager setDesiredAccuracy:kCLLocationAccuracyHundredMeters];
    
    [locationManager setLocationTimeout:6];
    
    [locationManager setReGeocodeTimeout:3];
}

以上都是JS 調(diào)OC 方法, 下面介紹OC 調(diào)用JS 方法
微信登錄為例

JS 寫法

    onWXCode:function (code) {
        console.log("onWXCode "+code)
        if(code == ''){
            console.log("onWXCode 1")
            this.m_WXLoginBt.interactable=true;
        }else{
            console.log("onWXCode 2" + code);
            code = encodeURI(code);
            var webUrl = WEB_HEAD + LOGIN_SERVER_IP + '/UserFunc.php?&GetMark=14&code=' + code;
            HttpUtils.getInstance().httpGets(webUrl, function (data) {  
                console.log("onWXCode 3")
                var Login = JSON.parse(data); 
                if(Login.errcode != null) return this.ShowAlert("ErrCode:" + Login.errcode);
                this.LoginAccount(Login.Accounts ,Login.LogonPass);
            }.bind(this));
            console.log("onWXCode 4")
        }
    },

OC 因?yàn)镺C 的字符串跟C++不一樣需要進(jìn)行一下轉(zhuǎn)碼, 而JS 要的字符串格式是json類型的字符串, 所以O(shè)C 這邊需要對(duì)字符串進(jìn)行拼接(當(dāng)然還有其他方法生成json字符串).

NSLog(@"%@", mutStr);
            //            NSString *str = [NSString stringWithFormat:@"{\"openid\":\"%@\",\"nickname\":\"%@\",\"sex\":\"%@\",\"headimgurl\":\"%@\"}",resp.openid,resp.name,resp.unionGender,resp.iconurl];
            
            NSString *str = [NSString stringWithFormat:@"{\"headimgurl\":\"%@\",\"nickname\":\"%@\",\"sex\":\"%@\",\"openid\":\"%@\"}",resp.iconurl,resp.name,resp.unionGender,resp.openid];
            
            
            NSLog(@"%@", str);
            //            std::string strRet1 = "{}";
//            NSString * encodingString = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            std::string strRet1 = [str UTF8String];
            
            std::string strRet = "onWXCode";
            
            NSLog(@"QQQQQQQQQ:::::%s",strRet1.c_str());
            std::string jsCallStr = cocos2d::StringUtils::format("CallLoginFunc(\"%s\",'%s');", strRet.c_str(),strRet1.c_str());

            NSLog(@"~~~~~~~~~~~~~%s",jsCallStr.c_str());
            
            se::Value *ret = new se::Value();
            se::ScriptEngine::getInstance()->evalString(jsCallStr.c_str() , -1 , ret);

轉(zhuǎn)json字符串時(shí)候有幾個(gè)坑, 因?yàn)镺C 的字符串中不能包含""的 在有""的地方需要加\轉(zhuǎn)義, 但是給JS 發(fā)過去的字符串又因?yàn)槎鄮讉€(gè)"'而獲取不到, 所以在后面C++拼接的時(shí)候選擇的是''單引號(hào), 這樣完美的避開了OC雙引號(hào)的問題. 當(dāng)然了因?yàn)镴S 那邊不是我寫的, 其實(shí)最好的辦法是JS 那邊不是接一個(gè)參數(shù), 而是多個(gè)參數(shù), 這樣就不會(huì)出現(xiàn)雙引號(hào)的問題. 這個(gè)問題坑了我一下午
