我最近尝试将 open feint 集成到我的应用程序中。当我的应用程序启动时，底部的“Welcome back player xxxx”可以正常工作，所以我知道 open feint 可以正常工作。但是，当我按下链接到它的按钮时

-(IBAction) leaderboard: (id) sender
{

 [OpenFeint launchDashboard];
}

我收到此错误：

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[DemoAppViewController leaderboard]: unrecognized selector sent to instance 0x7a40250'

在我看来，leaderboard当方法需要一个参数时，您似乎尝试向对象发送消息，因此您应该用一个参数调用它。

也就是说，看起来你正在做这样的事情：

[someDemoAppViewControllerObject leaderboard]

当你应该这样做时：

[someDemoAppViewControllerObject leaderboard:theSenderObject]

经常self被用作theSenderObject.

是

-(IBAction) leaderboard: (id) sender

在.h 文件中声明？
