ios - 将数组中的特定对象保存到新数组中

Question

我有一个名为 teamArray 的数组，其中包含一个带有 ID、名称和短名称的 teamObject。这些名称循环并填充到 tableView 中。所有这些单元格都可以被选中，当一个单元格被选中时，indexPath 被插入到一个 cellSelected 数组中。我想将 teamArray 中选定的单元格 ID 保存到一个新数组中。所以我想我需要将 cellSelected 数组 indexPath 与 teamArray 进行比较？我该怎么做？

数组

var teamArray = Array<Team>()
var cellSelected = NSMutableArray()

didSelectRowAtIndexPath

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    tableView.deselectRowAtIndexPath(indexPath, animated: true)

    if (self.cellSelected.containsObject(indexPath)) {
        self.cellSelected.removeObject(indexPath)
    } else {
        self.cellSelected.addObject(indexPath)


    }

    tableView.reloadData()
}

团队对象

class Team: NSObject{
    var id: Int!
    var name: NSString!
    var shortname: NSString!

    init(id: Int, name:NSString, shortname: NSString) {
        self.id = id
        self.name = name
        self.shortname = shortname
    }
}

Answer 1

var teamSelected = [团队]()

在您的 didSelectRowAtIndexPath 函数中:

let team = self.teamArray[indexPath.row] as Team
var removed = false

for (index, value) in enumerate(self.teamSelected) {
    if (value == team) {
        self.teamSelected.removeAtIndex(index)
        removed = true
    }
}

if (!removed) {
    self.teamSelected.append(team)
}

在您的 cellForRowAtIndexPath 函数中:

let team = self.teamArray[indexPath.row] as Team
var removed = false

for (index, value) in enumerate(self.teamSelected) {
    if (value == team) {    
        cell.accessoryView = cell.accessoryCheck
        removed = true
    }
}

if (!removed) {
    cell.accessoryView = cell.accessoryUncheck
}

当您想要访问所选 Team 的 ID 时，您可以循环遍历 teamSelected

编辑:将 cellSelected 的名称更改为 teamSelected
