打印附加结构 (swift4) [英] Print appended struct (swift4)

问题描述

我有三个文本文件，用于将数据附加到结构中.如何打印我附加的内容?现在我收到一条错误消息.

I have three textifleds that I am using to append data into a struct. How can I print what I appended? Right now I am getting a error message.

import UIKit

class ViewController: UIViewController {
    @IBOutlet var c: UITextField!
    @IBOutlet var a: UITextField!
    @IBOutlet var b: UITextField!
    var contacts: [Person] = []

    @IBAction func press(_ sender: Any) {
        contacts.append(Person(name: a.text!, surname: b.text!  , phone: Int(c.text!)!))
        print(ViewController.Person)
    }

    struct Person {
        var name: String
        var surname: String
        var phone: Int
    }
}

推荐答案

我已经修改了你的代码，你可以使用它，它会给你你想要的结果.

I have modified your code, you can use it it will give you result what you want.

import UIKit

class ViewController: UIViewController {
@IBOutlet var c: UITextField!
@IBOutlet var a: UITextField!
@IBOutlet var b: UITextField!
var contacts: [Person] = []
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.


}
@IBAction func press(_ sender: Any) {
    contacts.append(Person(name: a.text!, surname: b.text!  , phone: Int(c.text!)!))
    print(self.contacts.description)
}

struct Person {
    var name: String
    var surname: String
    var phone: Int

}}

我刚刚对打印语句进行了一项更改.作为您查看控制器本身中的联系人数组，您可以直接使用它并使用函数描述来打印联系人的更新值.

I have just made one change in print statement. As your contacts array in you view controller itself so you can directly use it by self and use function description for printing updating values of contacts.
