Question

还有许多其他类似的问题，但是缺乏答案，每个项目都有所不同。我有这个错误 '方法调用的参数太多，预期为1，有2个？' 但是在以前的数组中，我使用过这个错误没有发生？它可能是代码的问题，但我不确定？我一直在寻找可能影响它的其他错误，但没有运气。以下是我的编码，

非常感谢任何帮助。谢谢。错误出现在我放置'***'

Answer 1

如果您指出哪条线路造成问题会很好，但我认为无论如何我都找到了它：

[NSArray arrayWithObject:@"Leaderboard", nil];

arrayWithObject只需要一个对象，而不是逗号分隔的对象数组。请改用以下内容：

[NSArray arrayWithObject: @"Leaderboard"];

或者，为了与周围的代码更加一致，请使用

[NSArray arrayWithObjects: @"Leaderboard", nil];

方法调用的参数太多，预期为1，有2？（Xcode）
