如何在Swift3中更改NSIndexPath初始化？ [英] How has the NSIndexPath initialization changed in Swift3?

问题描述

我正在尝试跟随Apple的开始开发iOS应用程序（Swift）教程并几乎完成了它。我不得不修改教程的几个部分，因为我正在使用Xcode 8（我认为使用Swift 3而不是Swift 2）。但是，我遇到了以下编译器错误，我不知道原因：

I'm trying to follow along with Apple's Start Developing iOS Apps (Swift) tutorial and have almost completed it. I have had to amend several parts of the tutorial as I'm using Xcode 8 (which I think uses Swift 3 instead of Swift 2). However, I am running into the following compiler error and I don't know why:

参数标签（forRow：，inSection）不匹配以下函数中的任何可用重载

：

@IBAction func unwindToMealList(sender: UIStoryboardSegue) {

    if let sourceViewController = sender.sourceViewController as? MealViewController, meal = sourceViewController.meal {
        // Add a new meal
        let newIndexPath = NSIndexPath(forRow: meals.count, inSection: 0)
        meals.append(meal)
        tableView.insertRows(at: newIndexPath, with: .bottom)
    }

}

我猜测NSIndexPath有一个不同的初始化程序，它在Swift 3中已经改变但我找不到它。我做错了吗？

I'm guessing that there is a different initialiser for NSIndexPath that's changed in Swift 3 but I can't find it. Am I doing something wrong?

谢谢，

推荐答案

NSIndexPath 已更改为 IndexPath

尝试 IndexPath（row：Int，section：Int）

API参考：indexpath
