json - Swift - JSON 数组值

Question

我在输出中得到以下 JSON 值:

[["category_title": Shelly], ["category_title": Thaddeus],
["category_title": Chantale], ["category_title": Adara],
["category_title": Mariko], ["category_title": Felicia]]

但我想要如下所示:

["Shelly","Thaddeus","Chantale", "Adara","Mariko","Felicia"]

我有以下 Swift 代码。请帮助我获得以上输出。

func successGetTermsData(response: Any){
    var UserRole : String = ""
    var arrayOfDetails = response as? [[String: Any]] ?? []

    UserRole = arrayOfDetails as? String ?? ""
    print(arrayOfDetails)
}

Answer 1

您必须将Dictionary arrayOfDetails数组映射到String数组。 flatMap 忽略丢失的键。

if let arrayOfDetails = response as? [[String: String]] {
    let userRole = arrayOfDetails.flatMap { $0["category_title"] }
    print(userRole)
}
