在 SWIFT 中遇到逗號時將字符串換行 (Break string to newline when meeting a comma in SWIFT)

問題描述

在 SWIFT 中遇到逗號時將字符串換行 (Break string to newline when meeting a comma in SWIFT)

我正在從 Web 服務接收字符串。我將我的標籤文本設置為該字符串的文本。但是，字符串包含逗號，我想將字符串分隔為新行，用逗號分隔。

示例：

var exampleString = "street Number,  City"

需要為

var wantedString = "street Number
                    City"

這就是我當前設置標籤文本的方式：

   self.AdresseLabel.text = self.SpillestedAdresse as String

任何想法如何拆分字符串？

謝謝！

參考解法

方法 1:

You don't need anything fancy, just replace comma with new lines:

let wantedString = exampleString.stringByReplacingOccurrencesOfString(", ", withString: "\n")

方法 2:

If your intention is to replace a comma (followed by zero, one or more space characters) by a newline character, then a string replacement with a regular expression pattern is an option:

let exampleString = "street Number,  City"
let wantedString = exampleString.stringByReplacingOccurrencesOfString(",\\s*",
    withString: "\n",
    options: .RegularExpressionSearch)

print(wantedString)

Output:

street Number
City
