Swift将逗号分隔的字符串转换为NSMutableArray

Question

我有以下字符串

var points = "4,5"

我想转换为一个可变数组,所以它变成[4,5]我尝试了以下但它没有用

   var points = "4,5" 
   var selectedArray : NSMutableArray = [points]

Answer 1

干得好:

var points = "4,5"
var pointsArr = split(points) {$0 == ","}

要么

var pointsArr = points.componentsSeparatedByString(",")

正如gomfucius所说:

var arr = points.components(separatedBy: ",")
