我有一个这样的课

class FoundItem : NSObject {

var id : String!
var itemName : String!
var itemId : Int!
var foundBy : String!
var timeFound : String!

init(id: String,
    itemName: String,
    itemId: Int,
    foundBy: String,
    timeFound: String)

{
    self.id = id
    self.itemName = itemName
    self.itemId = itemId
    self.foundBy = foundBy
    self.timeFound = timeFound

}

我把它引用到我的身上

class MapViewVC: UIViewController, MKMapViewDelegate {

var found = [FoundItem]()

var filterItemName : String()

}

我FoundItem是从我的类中FoundItem的一个字典数组生成的firebase查询.然后我得到一个itemName从另一个视图控制器生成的字符串,该控制器是didSelection函数的集合视图.我想获取该字符串,然后使用与我之前itemName的itemName …

您好，我有一个包含多个值的数组，我想尝试过滤掉搜索栏的索引。英语术语的一个例子就像。给我名称“Name2”的索引，并通过检查每个索引的第一个值中的所有字符串来执行此操作。

代码：

 // Multiple Errors 

 var receivedList = [["Name1","Apple","Fresh"],["Name2","Orange","Rotten"],["Name3","Pear","Fresh"],["Name4","Grape","Rotten"]]


 filteredData = data.filter({$0 == searchBar.text})
 filteredData = receivedList.filter({$0 receivedList[1] == searchBar.Text})


 //Im not really sure how to use this or if it's even useful 

 let searchPredicate = NSPredicate(format: "Orange CONTAINS[C] %@", searchText)

 let array = (receivedList as NSArray).filtered(using: searchPredicate)
