我已经阅读了所有与此相关的文章,但仍然出现错误:
'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (5) must be equal to the number of rows contained in that section before the update (5), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'
详细信息如下:
在.h
我有一个NSMutableArray
:
@property (strong,nonatomic) NSMutableArray *currentCart;
在.m
我numberOfRowsInSection
看来是这样的:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return ([currentCart count]);
}
要启用删除和从阵列中删除对象:
// Editing of rows is enabled
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
//when delete is tapped
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
[currentCart removeObjectAtIndex:indexPath.row];
}
}
我以为,通过让我的节数依赖于我正在编辑的数组的数量,可以确保适当的行数?在删除行时是否不必重新加载表就可以做到吗?
