我试过了：
- (IBAction)delete:(UIButton*)sender{
NSIndexPath *indexPath = [self.collectionView indexPathForCell:(TourGridCell *)[[[sender superview]superview]superview]];
}
但NSLog显示单元格存在,但indexpath为零.
解决方法
好的,这是：
- (IBAction)delete:(UIButton *)sender{
NSIndexPath *indexPath = nil;
indexPath = [self.collectionView indexPathForItemAtPoint:[self.collectionView convertPoint:sender.center fromView:sender.superview]];
}
