iphone - 从 UItableview 中删除一行时崩溃

Question

当使用 commitEditingStyle 从 Uitableview 中删除一行时，我的应用程序崩溃并出现此错误。

Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit_Sim/UIKit-1912.3/UITableView.m:1046 .Terminating app due to uncaught exception NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (2) must be equal to the number of rows contained in that section before the update (1), 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).

这是我的代码:

- (void)tableView:(UITableView *)tv commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    // If row is deleted, remove it from the list.
    if (editingStyle == UITableViewCellEditingStyleDelete) {
      order *OrderObj= [appDelegate.orderArray objectAtIndex:[indexPath row]];
       [appDelegate removeitem:OrderObj];

        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }   }

Answer 1

尝试更改这些行:

order *OrderObj= [appDelegate.orderArray objectAtIndex:[indexPath row]];
[appDelegate removeitem:OrderObj];

到:

[appDelegate.orderArray removeObjectAtIndex:[indexPath row]]; // assuming orderArray is NSMutableArray
