我想知道如何在UITextfield中输入内容然后通过UIButton将其发送到变量?
当我尝试使用此代码时,应用会自动崩溃并向我显示此错误:
线程:1信号SIGABRT
以下是代码:
import UIKit
import Foundation
class ViewController: UIViewController {
@IBOutlet weak var LabelHeure: UILabel!
@IBOutlet weak var Heure: UITextField!
@IBAction func Send(sender: AnyObject) {
var one = String(Heure.text)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
LabelHeure.text = NSDateFormatter.localizedStringFromDate(NSDate(),dateStyle:NSDateFormatterStyle.MediumStyle,timeStyle: NSDateFormatterStyle.NoStyle)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
答案 0 :(得分:0)
您不需要将Heure.text强制转换为字符串,因为它已经是字符串。

这是我使用的代码,它起作用。按下按钮后,变量将使用文本字段中的文本进行更新。我用println来验证。
import UIKit
import Foundation
class ViewController: UIViewController {
@IBOutlet weak var LabelHeure: UILabel!
@IBOutlet weak var Heure: UITextField!
@IBAction func Send(sender: AnyObject) {
var myVariable = Heure.text
println(myVariable)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
