NSMutableArray 到 Swift iOS 的字符串转换数组 [重复]

Question

我需要在表格视图中填充数据。如何在 Swift iOS 中将 [NSMutableArray?] 转换为 [(String)]

println(self.subcategory[index]!) 即 [NSMutableArray?]，其中 index is Int 显示：

(
    Operations,
    Marketing,
    "Public Relations",
    "Human Resources",
    Advertising,
    Finance,
    Hotels,
    Restaurants,
    Other
)

Answer 1

试试这个。

 let myArray : NSMutableArray = ["Operations"]
    myArray.addObject("Marketing")
    myArray.addObject("Public Relations")
    myArray.addObject("Human Resources")

    myArray.addObject("Advertising")
    myArray.addObject("Finance")
    myArray.addObject("Hotels")
    myArray.addObject("Restaurants")
    myArray.addObject("Other")

    NSLog("\(myArray)")

    var string = myArray.componentsJoinedByString(",")
    NSLog("\(string)")
