我想在山狮(os x 10.8)上的xcode 4.4中安装SDK 4.3,但是当我从xcode 4.1安装4.3 sdk软件包并从xcode 4.4启动模拟器时,模拟器只是告诉我ios模拟器找不到SDK.

可能需要重新安装sdk,这意味着它无法运行!xcode 4.4 GM出了什么问题？

有没有关于如何解决这类问题的想法？

我将以下代码添加到appDelegate.m中

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
}

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if (motion == UIEventSubtypeMotionShake )
    {
        // User was shaking the device. Post a notification named "shake".
        [[NSNotificationCenter defaultCenter] postNotificationName:@"shake" object:self];
    }
}

- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
{   
}

- (void)shakeSuccess
{
    // do something...
}

然后我补充说:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    // INIT THE BACKGROUND PATH STRING

    [self refreshFields];
    [self.window addSubview:navController.view];
    [self.window makeKeyAndVisible];
    ***[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(shakeSuccess) name:@"shake" …

现在我想传递一个void*指向Lua 的指针,使用userdata？这该怎么做？

顺便说一下,我用过luabind,但是它无法通过一个void*指向Lua堆栈的指针,这很烦人!你们能帮助我吗？

struct Event
{
     A* a;
     B* b;
     ...
};

Event *e;
void* instance = (void*)e;


// param is a parameter that is passed from Lua script. param is a Event object. And I cast it into a void* type
string Answer(void* param)
{
    WorkEvent *pWorkEvent = static_cast<WorkEvent*>(param);
    ASSERT_RET(pWorkEvent, NULL);

    string call_id = pWorkEvent->GetCallId();
    CCmThreadManager::TType thrd_id =  pWorkEvent->GetHandleThrdID();
    Coroutine *pco    = pWorkEvent->m_pco;
