如何在Swift 3.0中从字符串中提取单词（英语）和名称？

我把这个类拼凑在一起，它是真实代码和伪代码的混合体。我将为名字和姓氏创建一个单例类。有关详细信息，请参见代码中的注释。这不是全部，但它应该可以解决您的大多数问题。

更新cleanUpString使用switch语句调整了该方法。

更新2添加了此功能以照顾所有UITextChecker不想要的东西...

return UIReferenceLibraryViewController.dictionaryHasDefinition(forTerm: self)

无论您从何处获取OCR文本，都可以像这样使用它：

let stringParser = StringParser()
let cleanedUpText = stringParser.cleanUpString(yourOCRText)

这是课程：

import UIKit // need this so UITextChecker will work
import Foundation

class StringParser: NSObject {

    // TODO: You'll need to create a singleton class for your first and last names
    // https://krakendev.io/blog/the-right-way-to-write-a-singleton

    func cleanUpString(_ inputString: String) -> String {

        // chuck stuff separated by a space into an array as an invdividual string
        let inputStringArray = inputString.characters.split(separator: " ").map(String.init)

        var outputArray = [String]()

        for word in inputStringArray {
            // Switch to check if word satisfies any of the desired conditions...if so, chuck in outputArray

            switch word {
            case _ where word.isRealWord():
                outputArray.append(word)
                break
            case _ where word.isFirstName():
                outputArray.append(word.capitalized)
                break
            case _ where word.isLastName():
                outputArray.append(word.capitalized)
                break
            default:
                break
            }
        }

        // reassemble the cleaned up words into an output array and return it as a single string
        return outputArray.joined(separator: " ")
    }
}

extension String {

    func isFirstName() -> Bool {
        let firstNameArray = ["Andrew", "Sharon"] // FIXME: this should be your singleton

        return firstNameArray.contains(self.capitalized)
    }

    func isLastName() -> Bool {
        let lastNameArray = ["Webster", "Hazelwood"] // FIXME: this should be your singleton

        return lastNameArray.contains(self.capitalized)
    }

    func isRealWord() -> Bool {
        // adapted from https://www.hackingwithswift.com/example-code/uikit/how-to-check-a-string-is-spelled-correctly-using-uitextchecker
        let checker = UITextChecker()
        let range = NSRange(location: 0, length: self.utf16.count)
        let misspelledRange = checker.rangeOfMisspelledWord(in: self, range: range, startingAt: 0, wrap: false, language: "en")

        if misspelledRange.location == NSNotFound {
            // cleans up what UITextChecker misses
            return UIReferenceLibraryViewController.dictionaryHasDefinition(forTerm: self) // returns yes if there's a definition for it
        }
        return false
    }
}
