如何检查特定的string: String 是否包含特定的character: Character？

【问题讨论】：

我发现在 2020 年解决它的最简单方法是：。 s = "hello" 然后s.contains("e")。

标签： string swift character contains

【解决方案1】：

let char: Character = "e"

let string: String = "William"

let result = string.rangeOfString("\(char)")

if let result = result {
    //The string contains the character
    print("It contains")
}else{
    //The string doesn't contain the character
    print("It doesn't contain")
}

【解决方案2】：

string.characters.contains(character)

例子：

let string = "Hello, World!"
let character: Character = "e"

if string.characters.contains(character) {
    print("\(string) contains \(character).")
} else {
    print("\(string) doesn't contain \(character).")
}
