1.获取某个Cell
CGPoint subviewPosition = [sender convertPoint:CGPointZero toView:self.cartTableView];
NSIndexPath* indexPath = [self.cartTableView indexPathForRowAtPoint:subviewPosition];
CartViewCell * cell = (CartViewCell *)[self.cartTableView cellForRowAtIndexPath:indexPath];
// CartViewCell * cell = (CartViewCell *)[[[sender superview] superview] superview];
checkIndexPath = [self.cartTableView indexPathForCell:cell];
DLog(@"%@",checkIndexPath);
SNm8CartModel *cartModel = self.yoShopingModel.m8ShopsListArray[checkIndexPath.section];
2.刷新某个Cell
//一个section刷新
NSIndexSet *indexSet=[[NSIndexSet alloc]initWithIndex:2];
[tableview reloadSections:indexSetwithRowAnimation:UITableViewRowAnimationAutomatic];
//一个cell刷新
NSIndexPath *indexPath=[NSIndexPath indexPathForRow:3inSection:0];
[tableView reloadRowsAtIndexPaths:[NSArrayarrayWithObjects:indexPath,nil]withRowAnimation:UITableViewRowAnimationNone];
