Question

在Objective-C或Swift中，如何通过搜索单词的一部分来获取单词？

例如：“我没有 w一切”

搜索键：“否”

结果：知道

要查找的任何方法吗？

Answer 1

使用 Swift 2 ，我们可以使用“containsString”和“filter”：

let fullString = "I know everything"
let stringToFind = "no"

let wordsFound = fullString.componentsSeparatedByString(" ").filter { $0.containsString(stringToFind) }

print(wordsFound)

结果：

[ “知道”]

如果你给它一个包含多个匹配单词的句子，它会返回所有匹配项：

let fullString = "I know everything, nothing else"

结果：

[“知道”，“没有”]

与 Swift 3 相同：

let wordsFound = fullString.components(separatedBy: " ").filter { $0.contains(stringToFind) }

Answer 2

NSString *fullString = @"I know everything";
NSString *stringToFind = @"no";

NSArray *components = [fullString componentsSeparatedByString:@" "];

for (NSString *word in components)
{
  NSRange range = [word rangeOfString:stringToFind options:NSCaseInsensitiveSearch];
  if (range.location != NSNotFound)
  {
    NSLog(@"word we are looking for: %@", word);
  }
  else
  {
    NSLog(@"word %@ not contains substring", word);
  }
}

Answer 3

let testString = "I know everything, nothing else"
let testWord = "no"
var wordsContainingTestWord = [String]()

let words = testString.componentsSeparatedByString(" ")

for word in words {
    if word.containsString(testWord) {
        wordsContainingTestWord.append(word)
    }
}

print(wordsContainingTestWord)

打印[＆＃34;知道＆＃34;，＆＃34;没有＆＃34;]

通过搜索单词
