Question

我创建了这个集合视图控制器来显示游戏中的关卡数量我想知道用户选择的级别所以我想将所选的项目编号传递给gameviewcontroller

这是我现在在集合视图控制器中的代码

verride func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    let path = collectionView?.indexPathsForSelectedItems()
    let gamevc = GameViewController
    gamevc = segue.destinationViewController
}

这似乎不起作用，我如何将选择的项目编号传递给gameviewcontroller？

Answer 1

将var paths = [AnyObject]()作为实例变量添加到GameViewController，然后在gamevc.paths = path之后添加let gamevc = GameViewController

Answer 2

看起来这样有效

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
let path = collectionView?.indexPathsForSelectedItems()
let gamevc = GameViewController()
gamevc.paths = path!
gamevc = segue.destinationViewController as GameViewController

现在我的Gameviewcontroller中有一个标签和一个带有indexpath.row数字的图像。如何让单元格可点击，当我点击它时应该带我到GameViewController并将gamevc的lable.text更改为indexpath.row的数字？

将所选项值传递给新视图控制器swift
