NSMutableArray到String转换Swift iOS的数组

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是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)")
