如何从 UICollectionViewCell 访问 UICollectionView 中 Cell 的 indexPath [英] how to access from UICollectionViewCell the indexPath of the Cell in UICollectionView

问题描述

我想在调用操作时为 UICollectionViewCell 设置动画.
我已经在 Interface Builder 中完成了 UICollectionViewCell，UICollectionView 也是如此.现在我想在我的 actionBtnAddToCard 方法中获得正确的 indexPath.

i want to animate the UICollectionViewCell when action is called.
i have done UICollectionViewCell in Interface Builder, the UICollectionView also. Now i want to get the correct indexPath at my actionBtnAddToCard method.

这就是我现在尝试的方式(ProduktViewCell.m 中的方法):

thats the way i try it now (method in ProduktViewCell.m):

- (IBAction)actionAddToCart:(id)sender {
    XLog(@"");

    // see this line
    NSIndexPath *indexPath = ??** how can i access the correct indexPath**??;
    SortimentViewController *svc = [[SortimentViewController alloc] initWithNibName:@"SortimentViewController_iPad" bundle:[NSBundle mainBundle]];
    [svc.collectionViewProdukte cellForItemAtIndexPath:indexPath];

    [svc collectionView:svc.collectionViewProdukte didSelectItemAtIndexPath:indexPath];
} 

SortimentViewController 是继承 UICollectionView 的 viewController.
如何访问正确的 indexPath?

SortimentViewController is the viewController which inherits the UICollectionView.
how to acces the correct indexPath?

推荐答案

如果你知道视图层次结构就很容易了.

if you know the view hierarchy it is easy.

UIButton *button = (UiButton *) sender;

如果按钮是这样的-> UITableViewCell->按钮

那么你可以得到这样的单元格

then you can get cell like this

UITableViewCell *cell = (UITableViewCell *)[button superview];

如果按钮是这样的-> UITableViewCell -> 内容视图-> 按钮

UITableViewCell *cell = (UITableViewCell *)[[button superview] superview];

最后可以像这样提取索引路径

and finally index path can be extracted like this

NSIndexPath *indexPath = [self.table_View indexPathForCell:cell];
