ios - 访问数组元素并将其与所选数据的单元格匹配

Question

我有餐厅名称、项目和价格以以下形式存储 ( { 汉堡点 ( { 项目名称 = 商品价格 = } ) } )

现在我想访问数组元素并传递给 RestaunrantViewController，当我选择具有每个餐厅名称对应名称的 collectionviewcell 时，另一个 View Controller 中有一个 UITableView，我想显示 itemName 和 ItemPrice。 但我不知道我该怎么做

我正在使用它访问 ResturantFile.plist

 let pathUrl =  Bundle.main.path(forResource: "ResturantFile", ofType: ".plist")
    print("path url is",pathUrl)

    let finalArray = NSMutableArray(contentsOfFile: pathUrl!)
    print("final Array is",finalArray)

并没有选择方法代码是:

 func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath){

    let pathUrl =  Bundle.main.path(forResource: "ResturantFile", ofType: ".plist")
    print("path url is",pathUrl)

    let finalArray = NSMutableArray(contentsOfFile: pathUrl!)
    print("final Array is",finalArray)

    let itemNames = finalArray?.sorted(by: {$0 == "ItemName"})// this is not working for me

    // pass restaurant name and image to the restaurntviewcontroller via viewcontroller
    if blockClosure != nil{ blockClosure(restaurantImageArray[indexPath.row] ,restaurantNameArray[indexPath.row] , data)
    }
}

这是我的 ResturantFile.plist

在 RestaurantViewController 中，您需要像这样使用选定的餐厅名称添加过滤器(将“selectedRestroName”替换为来自先前 Controller 的选定餐厅名称):

let pathUrl = Bundle.main.path(forResource: "ResturantFile", ofType: ".plist") print("path url is",pathUrl) 
let finalArray = NSMutableArray(contentsOfFile: pathUrl!) 
///finalArray is plish Data array, and "selectedRestroName" is the selected restaurant which is you passing from closure
    let selectedDict = finalArray.filter { (object) -> Bool in
        (object.keys).contains(where: {$0 == "selectedRestroName"})
    }.first

    let finalArraaOfSelectedRestorentData = Array(selectedDict!.values)

或者

let finalArraaOfSelectedRestorentData = selectedDict["selectedRestroName"]
