我有UICollectionView
:
class BoatMatchingGame: UICollectionViewController, UICollectionViewDelegateFlowLayout, UICollectionViewDataSource {
我还有一个针对不同ViewController
的课程,我试图将其划分为:
class GameOutcome: UIViewController {
@IBOutlet var gameOutcomeLabel: UILabel!
var boatMatchingGame: BoatMatchingGame!
override func viewDidLoad() {
super.viewDidLoad()
gameOutcomeLabel.text = gameOutcomeText
}
}
在BoatMatchingGame
课程中,我有prepareForSegue
方法:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let gameOutcome = segue.destinationViewController as GameOutcome
gameOutcome.boatMatchingGame = self;
}
在didSelectItemAtIndexPath
方法中,我想执行segue
:
switch indexPath.item {
case 14:
self.performSegueWithIdentifier("Quit Matching Game", sender: self)
我在故事板中设置了标识符"Quit Matching Game"
。当我运行该程序并在cell
14处选择indexPath
时,我在以下错误中遇到以下错误:Thread 1: EXC_BREAKPOINT (code=EXC_1386_BPT, subcode=0x0)
:0x202ebd8: popl %ebp
注意:我确实有一个标签在这个单元格中每秒都在变化。
谢谢!

答案 0 :(得分:0)
您似乎还没有真实地声明或初始化gameOutcomeText
GameOutcome
{\ n} viewDidLoad
中使用的gameOutcomeText
变量。
如果在BoatMatchingGame
类中设置BoatMatchingGame
,则可以使用传递到GameOutcome
视图控制器的override func viewDidLoad() {
super.viewDidLoad()
gameOutcomeLabel.text = boatMatchingGame.gameOutcomeText
}
实例访问它,如下所示:
{{1}}
