Question

我有6个UITextfields，我想将它们全部放入一个字符串中，这样我就能得到输入到UItextField的内容。

示例：在UItextfield1中，我输入了数字＆＃34; 3＆＃34;，然后在UItextfield2中，我输入了数字＆＃34; 5＆＃34;，依此类推。我想把它放到一个字符串中，所以它读取＆＃34; 35＆＃34; ....

以下是我的代码。任何帮助都会很棒！

class EnterUsersCode: UIViewController {

    var textField1: UITextField! = {
        let tf = UITextField()
        tf.text = ""
        return tf
    }()

    var textField2: UITextField! = {
        let tf = UITextField()
        tf.text = ""
        return tf
    }()

    var textField3: UITextField! = {
        let tf = UITextField()
        tf.text = ""
        return tf
    }()

    var textField4: UITextField! = {
        let tf = UITextField()
        tf.text = ""
        return tf
    }()

    var textField5: UITextField! = {
        let tf = UITextField()
        tf.text = ""
        return tf
    }()

    var textField6: UITextField! = {
        let tf = UITextField()
        tf.text = ""
        return tf
    }()

    var textFieldArray: [UITextField] {
        return [textField1!, textField2!, textField3!, textField4!, textField5!, textField6!]

}

Answer 1

你可以尝试

 let str = "\(textField1.text)\(textField2.text)"

或者将所有字符串连接成一个字符串

let str = textFieldArray.compactMap{$0.text}.joined()

Answer 2

使用textFieldArray获取文本字段，并通过循环将text属性中的字符串附加到变量：

func getConsolidatedString() -> String {
    var finalString = ""
    for textField in textFieldArray {
        finalString += textField.text ?? ""
    }
    return finalString
}

Answer 3

您可以使用+如下所示连接字符串：

let str = textField1.text + textField2.text + textField3.text + textField4.text + textField5.text + textField6.text

如何在Swift 4上将多个UITextField放入一个字符串？
