Question

需要过滤数组的帮助。

let array = [pair: "TZS_SFDT", pair: "TZFD_TG", pair: "G_TDDD"]

我如何在两个对象中分隔字母组，如：

arraySeperated1 = [part1: "TZS", part1:"TZFD", part1: "G"]
arraySeperated2 = [part2: "SFDT", part2: "TG", part2: "TDDD"]

感谢您的帮助！

最好我可以处理你的非法代码（致命错误：字典文字包含重复的密钥），而不是将其视为/解释为字符串数组：

let array = ["TZS_SFDT", "TZFD_TG", "G_TDDD"]

然后分开它：

let arraySeparated1 = array.map { $0.substring(to: $0.range(of: "_")!.lowerBound) }
let arraySeparated2 = array.map { $0.substring(from: $0.range(of: "_")!.upperBound) }

好的，在评论澄清之后，你确实得到了：

let array = [[pair: "TZS_SFDT", description: "", Value: 0],
             [pair: "TZFD_TG", description: "", Value: 0],
             [pair: "G_TDDD", description: "", Value: 0]]

所以你分成：

let arraySeparated1 = array.map { ["part1":$0.pair.substring(to: $0.pair.range(of: "_")!.lowerBound)] }
let arraySeparated2 = array.map { ["part2":$0.pair.substring(from: $0.pair.range(of: "_")!.upperBound)] }
