JavaScript和Lua两者分别调用Native OC接口通道，实现这两个框架的协调工作。
H5+ SDK以插件的实现客户化的调用Native OC，Lua则可以通过tolua工具实现。
开发H5+ SDK插件
PluginTest.h
@interfacePGPluginTest : PGPlugin
- (void)gotoMyGame:(PGMethod*)commands;
+ (void) back2App;
@end
PluginTest.mm
@implementationPGPluginTest
- (void)gotoMyGame:(PGMethod*)commands
{
NSString* cbId = [commands.arguments objectAtIndex:0];
// 用户的参数会在第二个参数传回
NSString* pArgument1 = [commands.arguments objectAtIndex:1];
NSLog(@"gotomygame>>>:%@",pArgument1);
NSString* pResultString = @"success";
// 运行Native代码结果和预期相同，调用回调通知JS层运行成功并返回结果
PDRPluginResult *result = [PDRPluginResult resultWithStatus:PDRCommandStatusOK messageAsString:pResultString];
AppManager* mgr = [AppManager getInstance];
mgr.gameName = [NSString stringWithFormat:@"%@%@%@",@"games/",pArgument1,@"/src/main.lua" ];
mgr.ccView = [[CocosViewController alloc] init];
mgr.h5View = [[mgr.navigationController viewControllers] objectAtIndex:0];
[mgr.navigationController pushViewController:mgr.ccView animated:YES];
[self toCallback:cbId withReslut:[result toJSONString]];
}
+ (void) back2App
{
[[AppManager getInstance] releaseCocos];
}
实现C++ tolua
LuaHelper.mm
int LuaHelper::back2App()
{
CCLOG("LuaHelper back2App");
[PGPluginTest back2App];
return 1;
}

quick_module_register方法调用luaopen_GameUtil_luabinding(L)以便于Lua调用C++接口
窗口管理
关系图如下：
AppManager.h:为了管理整个应用的所有UIWindow和UIController的加载和移除。
static AppManager *instance=nil;
@implementation AppManager
@synthesize gameName;

static dispatch_once_tonceToken ;
dispatch_once(&onceToken,^{
instance = [[super allocWithZone:NULL] init] ;
}) ;
return instance;
}
+(id) allocWithZone:(struct _NSZone *)zone
{
return [AppManagerinstance] ;
}
-(id) copyWithZone:(struct _NSZone *)zone
{
return [AppManagerinstance] ;
}
//释放cocos所有变量
