推荐答案

假设您有以下数组，

    var txtArray:[UITextField] = [UITextField]()

    for i in 0...4 {
        let txtField = UITextField(frame: .zero)
        txtField.text = "\(i)"
        txtField.tag = i
        txtArray.append(txtField)
    }

要获取值，您必须执行以下操作

To get values you have to do following,

    let sorted = txtArray.sorted { $0.tag < $1.tag }
    let values = sorted.map { return $0.text! }
    let test = values.joined(separator: " ")

    print(test)

输出将为

0 1 2 3 4
