cocos creator和Objective-C互调用

本文为ios开发环境下js和obc相互调用的例子。

一 、js调用oc

js

if (cc.sys.isNative&&cc.sys.os==cc.sys.OS_IOS) {
           let ret = jsb.reflection.callStaticMethod("AdMaster","showAd:title:","有志者事竟成","淡定");
       }

oc建一个AdMaster文件，继承NSObject
.h文件

+(BOOL)showAd:(NSString *)str title:(NSString *)tit;

.m文件

+(BOOL)showAd:(NSString *)str title:(NSString *)tit{
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:tit message:str delegate:nil cancelButtonTitle:@"否" otherButtonTitles:@"是", nil];
    [alertView show];
    return true;
}

二、oc调用js

OC调用js方法用ScriptingCore。 bool evalString(const char *string);
OC端:

ScriptingCore::getInstance()->evalString("startJsCocosScene002()");

js端：

function startJsCocosScene002(){
    console.log("main.js....startJsCocosScene002...")
    cc.director.runScene(new HelloWorldScene002());
    return 1;
}

带参数的oc调用js

-(void)callJsEngineCallBack:(NSString*) funcNameStr withCmd:(NSString*) cmdStr withContent:(NSString*) contentStr
{
    NSLog(@"callJsEngineCallBack...");

    string funcName = [funcNameStr UTF8String];
    string param001 = [cmdStr UTF8String];
    string param002 = [contentStr UTF8String];
    std::string jsCallStr = cocos2d::StringUtils::format("%s(\"%s\",\"%s\");",funcName.c_str(), param001.c_str(),param002.c_str());
    NSLog(@"jsCallStr = %s", jsCallStr.c_str());
    ScriptingCore::getInstance()->evalString(jsCallStr.c_str());
}

js

function jsEngineCallback(cmd,content){
    console.log("...jsEngineCallback..." + cmd + "..." +content);
};
