nsindexpath - UICollectionView cellForRow 崩溃

Question

您好，我无法在 UICollectionView 的索引路径获取自定义对象...下面是我的代码。

我正在崩溃

[玩家名字：]：unrecognized selector sent to instance

有什么建议么？

 - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView     cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
BenchCollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:CollectionCell forIndexPath:indexPath];
[cell setFrame:CGRectMake(0, 4, 120, 50)];


    Player*homeBenchPlayer = [[self homeBench]objectAtIndex:indexPath.row];

    cell.playerName.text = homeBenchPlayer.firstName;
    cell.playerPosition .text = homeBenchPlayer.position;
    cell.playerPicture.image = [ UIImage imageWithData:homeBenchPlayer.picture];

return cell;

}

当我意外收到此错误时，我通常会返回 IB，选择导致崩溃的对象，并调查 Connections Inspector。通常，问题似乎是不正确的引用插座或发送的事件。

这可能是由于performSelector:@selector(dismissModal:)在被调用者不存在的地方调用引起的。
