What is an ambiguous attitude?

[注意 此答案最初是基于Swift 2.2制定的。它已针对Swift 4进行了修订,包括两个重要的语言更改:第一个方法参数外部不再自动抑制,必须明确向Objective-C公开选择器。] 您可以通过将函数引用 强制转换 为正确的方法签名来解决此问题: let selector = #selector(test as () -> Void) 然而,我认为你不应该这样做. You could try int z = pow( static_cast(x), y ) + 0.1; Then again, integer powers of integer 2 are bitshift operations Are you trying to calculate the number of nanoseconds? In that case, you intended "multiply", like your code is doing.

Ambiguity Examples. Unfortunately, that is an extremely bad habit in C++ If the result is wrong, then a rounding floating points during conversion is the reason
