Question

我正在尝试将我的iPhone应用程序移植到Windows 8，我对此行有问题（它的目标是c）：

[self schedule:@selector(fire:)];

c ++上的等价物应该是：

this->schedule(schedule_selector(AirScene::fire));

AirScene是我班级的名称，但我在Visual Studio 2012中返回此错误：

error C2064: term does not evaluate to a function taking 1 arguments

因此，换句话说，找不到功能计划（选择器）。这很奇怪，因为我对非计划方法没有任何问题，你有什么想法吗？

Answer 1

<强>固定。

用于Windows 8模板的cocos 2d版本是旧版本，因此安排选择器的好方法是：

CCScheduler::sharedScheduler()->scheduleSelector(schedule_selector(AirScene::fire), this, 0, false);

计划选择器错误
