cocoa-touch - uicollection view 数据视图

Question

我是iphone新手。我的应用程序中有一个集合视图，它工作正常，但现在我想在另一个图像视图的下一个视图控制器中选择一个图像和我想要的那个图像。- (NSInteger)collectionView:

我使用以下代码：

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return recipeImages.count;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *identifier = @"Cell";

    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];

    UIImageView *recipeImageView = (UIImageView *)[cell viewWithTag:100];
    recipeImageView.image = [UIImage imageNamed:[recipeImages objectAtIndex:indexPath.row]];

    return cell;
}

Answer 1

实施collectionView:didSelectItemAtIndexPath:：

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
    UIImage *image = [UIImage imageNamed:[recipeImages objectAtIndex:indexPath.item]];
    // go on...
}
