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

我希望在调用操作时为 UICollectionViewCell 设置动画。

i已完成 UICollectionViewCell 在 Interface Builder 中， UICollectionView 也是。
现在我想在我的 actionBtnAddToCard 方法中获得正确的 indexPath 。

这就是我现在尝试的方式（ProduktViewCell.m中的方法）：

   - （IBAction ）actionAddToCart：（id）sender {
 XLog（@）; 
 
 //看到这一行$​​ b $ b NSIndexPath * indexPath = ?? **如何才能访问正确的indexPath ** ?? 
 SortimentViewController * svc = [[SortimentViewController alloc] initWithNibName：@SortimentViewController_iPadbundle：[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？

解决方案

如果您知道视图层次结构很容易。

  UIButton * button =（UiButton *）发件人;如果按钮是这样的  - > UITableViewCell  - >按钮 
 
 
 
那么你可以得到这样的单元格
  UITableViewCell * cell =（UITableViewCell *）[按钮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
  NSIndexPath * indexPath = [self.table_View indexPathForCell：cell]; 
  
 
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.

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 is the viewController which inherits the UICollectionView.

how to acces the correct indexPath?

解决方案
if you know the view hierarchy it is easy.
UIButton *button = (UiButton *) sender;
if the button is like this  - > UITableViewCell - > button

then you can get cell like this 
UITableViewCell *cell = (UITableViewCell *)[button superview];
if the button is like this  - > UITableViewCell - > content view -> button
UITableViewCell *cell = (UITableViewCell *)[[button superview] superview];
and finally index path can be extracted like this 
NSIndexPath *indexPath = [self.table_View indexPathForCell:cell];
