ios - 双击CollectionViewCell时如何进行事件？

Question

当我双击collectionview单元格时，我想创建一个事件
UIGestureRecognizer是解决此问题的唯一方法吗？

我要解决的代码很长而且很困难...
UICollectionView或UICollectionViewCell有什么支持吗？

Answer 1

在您的-cellForRowAtIndexPath中:

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(doubleTapped:)];
    tap.numberOfTapsRequired = 2;
    [cell addGestureRecognizer:tap];

而这种方法:

    -(void)doubleTapped:(UITapGestureRecognizer*)tap{
        UICollectionViewCell *doubleTappedCell = tap.view;
        NSIndexPath *indexPath = [self.collectionView indexPathForCell:doubleTappedCell];
}
