}是对的。但我不明白为什么它使用额外的行public void function(int number,for(int b;b>number;b++){int param2, int param3,int param4,int param5,int param6})
{ //start of body
for(int b;b>number;b++)
{
object[b].setter(param2)
object[b].setter(param3)
object[b].setter(param4)
object[b].setter(param5)
object[b].setter(param6)
}
}
？ “func”的含义是什么？
有人有任何线索吗？
sumOf ( )答案 0 :(得分：2)
第sumOf()行证明你可以完全没有参数地调用该函数。
答案 1 :(得分：0)
sumOf的课程都是＆＃34;不必要的＆＃34;对于功能本身。它只显示了用法。
Int...是一个可变参数
可变参数接受零个或多个指定类型的值。 https://developer.apple.com/library/watchos/documentation/Swift/Conceptual/Swift_Programming_Language/Functions.html
