ios - -[__NSCFNumber 行] : unrecognized selector sent to instance

Question

我已经检查了其他答案，但他们似乎没有正确回答我的问题。如果有明显的我没见过的，请帮我把它放在评论中:)

我有一个 tableView，它有一个 Realm 数据库作为数据源。我希望能够从源中删除已删除的单元格。

代码如下:

func objectsForSection(section: UInt) -> RLMResults {
    let categoryName = (Category.allObjects()[section] as Category).name
    return Product.objectsWhere("productCategory.name == '\(categoryName)'")
}


override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if editingStyle == .Delete {
        // Delete the row from the data source
        var realm = RLMRealm.defaultRealm()
        let productsForSection = objectsForSection(UInt(indexPath.section)) // This returns an RLMResults
        let product = productsForSection[UInt(indexPath.row)] as Product
        realm.beginWriteTransaction()
        realm.deleteObject(product)
        realm.commitWriteTransaction()
        tableView.deleteRowsAtIndexPaths([indexPath.row], withRowAnimation: .Fade)
    } else if editingStyle == .Insert {
        // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
    }    
}

当我滑动并按下删除时，它崩溃了。我做错了什么？

提前致谢!

你有一行内容是:

tableView.deleteRowsAtIndexPaths([indexPath.row], withRowAnimation: .Fade)

它传递一个带有行号的数组，而不是 NSIndexPath。

我相信你的意思是:

tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
