ios - Swift:将 UITextField 输入转换为字符串并在特定字符处分割字符串

Question

我正在尝试将 UITextField 内的文本转换为字符串，以便我可以在字符串上使用方法“componentsSeperatedByString(".") 将其转换为数组。但我不断收到 UITextField 的错误没有成员“componentsSeperatedByString”。有什么建议吗？谢谢

import UIKit
import Parse

class ViewController: UIViewController {


    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }




    @IBOutlet weak var username: UITextField!



    @IBOutlet weak var password: UITextField!



    //Login function. Drag Down keyboard after clicking login
    @IBAction func Login(sender: AnyObject) {
        username.resignFirstResponder()
        password.resignFirstResponder()

        var username_array: [String] = username.componentsSeperatedByString(".")


}
}

Answer 1

用户名是一个UITextField而不是String。试试这个:

var username_array: [String] = username.text.componentsSeperatedByString(".")
