启动 OpenFeint 仪表板时发生崩溃
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“欢迎回来玩家 xxxx”会起作用，所以我知道开放假动作正在起作用。但是，当我按下链接到此的按钮时，
-(IBAction) leaderboard: (id) sender
{
[OpenFeint launchDashboard];
}
我收到此错误：

我无法找到任何有关如何解决此问题的帖子，因此我们将不胜感激！提前致谢
I recently tried to integrate open feint into my app. When my app launches, the 'Welcome back player xxxx' at the bottom works so I know that open feint is working. However, when I press the button that has this linked to it
-(IBAction) leaderboard: (id) sender
{
[OpenFeint launchDashboard];
}
I get this error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[DemoAppViewController leaderboard]: unrecognized selector sent to instance 0x7a40250'

从例外情况来看，在我看来，当该方法需要一个参数时，您试图使用 Leaderboard 向您的对象发送消息，因此您应该使用一个参数来调用它。
也就是说，看起来您正在做这样的事情：
当您应该这样做时：
通常
self被用作theSenderObject。From the exception it looks to me as if you tried to message your object with
leaderboardwhen the method requires one argument and as such you should call it with one.That is, it looks like you are doing something like this:
When your should be doing this:
Quite often
selfis used astheSenderObject.是
在 .h 文件中声明的吗？
is
declared in the .h file?
