我想将firstVC数据传递给secondVC。
但是我不知道如何通过编程。
Class FirstVC: ViewController {
var firstText: String = "hello"
func goToSecondVC {
var vc: SecondVC = SecondVC()
vc.secondText = firstText
self.show(vc, sender:nil)
}
}
class SecondVC: ViewController {
var secondText: String = ""
override func viewDidLoad() {
print(secondText)
}
}
我在堆栈中搜索并找到以下答案。
还有没有故事板,segue,delegate和NSUserDefaults的答案?这个答案使用情节提要。
let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "newViewController") as! NewViewController
newViewController.stringVariable = stringVariable
self.present(newViewController, animated: true, completion: nil)
答案 0 :(得分:0)
在第一个ViewController中,
<?php
namespace App\Models\Admin;
use Illuminate\Database\Eloquent\Model;
class Payment extends Model
{
protected $table = "payments";
public $timestamps = false;
protected $cast = ["payDate"=> "DATE"];
}
在第二个ViewController中, //只需定义字符串
@IBAction func Some_Button(_ sender: Any) {
let secndVC = self.storyboard?.instantiateViewController(withIdentifier:
"SecondViewControllerID") as! SecondViewController
let someString = "this is my string" //Whatever You Want to pass.
secndVC.SomeString=someString
self.navigationController?.pushViewController(secndVC, animated: true)
}
您将在viewDidLoad中获取数据
var SomeString = ""
//that's it.
