swift - 从未知长度的字符串 SWIFT 中删除一个单词

Question

我正在尝试从未知长度的字符串中删除一个单词，这是我的代码。

if (newService.range(of: serviceStr) != nil){

    // I should remove selected word here

    print("remove selected")
}else{
    print("add select")
    let space = " , "
    newService = newService + space + serviceStr            
}

我已经尝试了很多方法，但是，我应该指定我不知道的每个代码的 offsetBy，因为它的用户按钮选择。

你可以写

import Foundation

var sentence = "This is a simple sentence"
let wordToRemove = "simple"


if let range = sentence.range(of: wordToRemove) {
   sentence.removeSubrange(range)
}

print(sentence) // This is a  sentence

If you also want to remove the additional space after the simple word replace this

let wordToRemove = "simple"

with this

let wordToRemove = "simple "
