Question

我试图从文本文件中获取一系列数字，并根据数字定义一个新变量。当我打印SettingsArray时，我得到以下内容：

[10,25,1,0,0,1,1,1,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,1,0， 1,1,25,500,0,1,250,250,250,500,500,500,10,10,10,200,200,200]

我正在寻找的是哪些数字，但出于某种原因，在检查If语句时，所有的SettingsArray元素都是这样的：

[2] String class name = _TtC10Foundation15_NSOpaqueString

显然不符合任何条件，为什么在检查If语句时数组元素会出现乱码？

let file = String(contentsOfFile: "/Users/UserGoesHere/Documents/Settings.txt", encoding: NSUTF8StringEncoding, error: nil)!
        var SettingsArray = split(file) {$0 == ","}
        var StepPortInvert = ""
        if SettingsArray[2] == "1" && SettingsArray[3] == "1" && SettingsArray[4] == "1" {
            var StepPortInvert = "00000000"
        }
        if SettingsArray[2] == "0" && SettingsArray[3] == "1" && SettingsArray[4] == "1" {
            var StepPortInvert = "00000001"
        }
        if SettingsArray[2] == "1" && SettingsArray[3] == "0" && SettingsArray[4] == "1" {
            var StepPortInvert = "00000010"
        }

您只需要声明StepPortInvert一次。 BTW 2,3,4 =＆＃34; 1,0,0和＃34;

let file = String(contentsOfFile: "/Users/UserGoesHere/Documents/Settings.txt", encoding: NSUTF8StringEncoding, error: nil)!
        var SettingsArray = split(file) {$0 == ","}
        var StepPortInvert = ""
        if SettingsArray[2] == "1" && SettingsArray[3] == "1" && SettingsArray[4] == "1" {
            StepPortInvert = "00000000"
        }
        if SettingsArray[2] == "0" && SettingsArray[3] == "1" && SettingsArray[4] == "1" {
            StepPortInvert = "00000001"
        }
        if SettingsArray[2] == "1" && SettingsArray[3] == "0" && SettingsArray[4] == "1" {
            StepPortInvert = "00000010"
        }

拆分字符串不符合条件[Swift]
