如何在 Swift 中过滤字符串数组

Question

通过使用Objective C，我使用NSPredicate过滤年份数组，

下面是代码。

  yearArray = [yearArray filteredArrayUsingPredicate:[NSPredicate
  predicateWithFormat:@"SELF != ''"]];

根据上面的代码，它在 Objective c 中工作正常，我必须在Swift 3中过滤数组，

什么是输入年份数组：-

( Year,"","","",JAN,"","","",FEB,"","","",MAR,"","","",APR,"","","",
  MAY,"","","",JUN,"","","",JUL,"","","",AUG,"","","",SEP,"","","",OCT
  ,"","","", NOV,"","","",DEC,"","","","",WIN,"","","",SPR,"","","",SUM
  ,"","","",AUT,"","","","",ANN)

需要过滤器输出数组

(Year,JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC,WIN,SPR,SUM,AUT,ANN)

请给出如何快速过滤数组的解决方案。

Answer 1

使用此代码：

let yearArray: [String] = ... // your array of type [String]

let filteredArray = yearArray.filter {
    !$0.isEmpty
}
