arrays - 错误 SIGABRT - 无法在我的 TableViewController 中加载多个数组

Question

我正在尝试将多个食物菜单数组加载到一个 TableViewController 中。主菜单显示 2 个按钮，1:早餐菜单 2:面包菜单。每次我按下它们时，模拟器都会崩溃并显示 SIGABRT 错误。在自己尝试了一个不眠之夜之后，我联系你来看看它......我用 segues 检查了所有的连接和按钮，一切都检查好了......

我的单元格有 3 个标签和一个图像，每个都有自己的数组。我划分了按钮以选择不同的内容模式。内容模式 1:早餐 & 内容模式 2:面包店..

对不起大家真的很想学习如何做到这一点!

按钮菜单 Controller :

import UIKit

类 foodMenuController: UIViewController {

@IBOutlet weak var mainMenuButton: UIButton!

var contentMode = 0

//Breakfast mode
@IBAction func breakfastButton(sender: AnyObject) {
    contentMode == 1

}

//Bakery mode
@IBAction func bakeryButton(sender: AnyObject) {
    contentMode = 2
}


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.


    //Hide navigation bar
        self.navigationController?.navigationBarHidden = true


     func viewWillAppear(animated: Bool) {
        self.navigationController?.navigationBarHidden = true
    }

}

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

    }

}

Answer 1

一般来说，将数据向前传递到下一个 View Controller 比从前一个 View Controller 获取数据更容易。因此，将 contentMode 移动到 BreakfastFoodControllerTableViewController(这是有道理的；它决定了 TVC 的“模式”)。

var contentMode = 0

然后将 foodMenuController().contentMode 的每个引用修改为 contentMode。

接下来，修改 FoodMenuController 以在 BreakfastFoodControllerTableViewController 的 segue 之前设置正确的值。执行此操作的位置是在 FooodMenuController 的 prepareForSegue 方法中:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let breakfastVC = segue.destinationViewController as! BreakfastFoodControllerTableViewController
    if segue.identifier == "showBreakfast" {
        breakfastVC.contentMode = 1
    } else if segue.identifier == "showBakery" {
        breakfastVC.contentMode = 2
    }
}

您需要确保每个 segue 在您的 Storyboard中都有正确的标识符:

不再需要 IBAction 方法 breakfastButton 和 bakeryButton。
