本人超级小小白,现在是这样的,我安装了Eureka开源框架并且用它创建了3行text row,用户填入内容后,我需要app里调用这3行text row里用户输入的值,试了很久都不行。
以下是代码:
import UIKit import Eureka class ViewController: FormViewController{ override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. //Set title for Navi Bar self.title="Data Manager" //Add one Section without title form +++ Section ("") //Add Text Row <<< TextRow("FirstTag"){ row1 in row1.title = "Project code" row1.placeholder = "Enter Project Code here" }.onChange { row1 in print(row1.value)} <<< TextRow("SecondTag"){ row2 in row2.title = "Username" row2.placeholder = "Enter Username here" }.onChange { row2 in print(row2.value)} <<< TextRow("ThirdTag"){ row3 in row3.title = "Password" row3.placeholder = "Enter Password here" }.onChange { row3 in print(row3.value)} // add "Log on" button let myFirstButton = UIButton() myFirstButton.setTitle("Log In", for: .normal) myFirstButton.setTitleColor(UIColor.white, for: .normal) myFirstButton.backgroundColor = UIColor.blue myFirstButton.frame = CGRect(x: 65, y: 260, width: 250, height: 50) myFirstButton.addTarget(self, action: #selector(self.pressed), for: .touchUpInside) self.view.addSubview(myFirstButton) } func pressed() { let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert) let okAction = UIAlertAction(title: "OK", style: .default, handler: nil) alertController.addAction(okAction) self.present(alertController, animated: true, completion: nil) print(TextRow.init(tag: "FirstTag").value) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. }
}
在viewLoad函数里面的onChange函数是可以的,可以print出返回值。但是我试图加了一个Alert message,目的是出现这个message 的时候可以print返回值,也就是这段代码,就报错了
print(TextRow.init(tag: "FirstTag").value)
不知道有人知道吗?小妹在此谢过了!!
付费偷看金额在0.1-10元之间
想了一下 是不是第一个函数没有返回值让第二个函数调用呀
