Question

我使用一个简单的导航控制器，使用IB在其上添加了一个集合视图。我在标题中声明了集合视图的委托和数据源，并在IB中将其连接起来。集合视图填充所有图像，并将滚动，但从不调用didSelectItemAtIndexPath。发生了什么事？

抱歉，在点击提交之前忘了复制代码。

- (void)viewDidLoad
{

    [super viewDidLoad];

     arryData = [[NSArray alloc] initWithObjects:@"AIMCON", @"Devotional Songs", @"Saved Devotionals", @"Resources", @"Podcasts", @"Website", @"Links",  nil];
    CALayer * l = [viewofimage layer];
    [l setMasksToBounds:YES];
    [l setCornerRadius:11];
    [l setBorderWidth:2.0];
    [l setBorderColor:[[UIColor blackColor] CGColor]];
    tableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        [self.collectionView registerClass:[CVCell class] forCellWithReuseIdentifier:@"cvCell"];

        self.collectionView.backgroundColor = [UIColor blackColor];
    }
    else {
        [self.collectionView registerClass:[CVCell class] forCellWithReuseIdentifier:@"cvCell"];

        self.collectionView.backgroundColor = [UIColor blackColor];

    }


    // Do any additional setup after loading the view.

Answer 1

正如评论中所讨论的，由于没有为delegate设置collectionView，问题就出现了。添加行

self.collectionView.delegate = self

解决问题

UICollectionView didSelectItem未调用
