当我尝试在请求的成功块中删除 UITableViewCell 时出现问题.

There is a problem when I try to delete UITableViewCell in success block of the request.

在我的

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

我正在通过AFNetworking进行请求

I am making request with AFNetworking

- (NSURLSessionDataTask *)POST:(NSString *)URLString parameters:(id)parameters success:(void (^)(NSURLSessionDataTask *task, id responseObject))success failure:(void (^)(NSURLSessionDataTask *task, NSError *error))failure

在此之后，我通过关闭SVProgressHUD并删除单元格来更新UI:

After that in success block I am updating UI by dismissing SVProgressHUD and deleting cell:

NSUserDefaults *usd = [NSUserDefaults standardUserDefaults]; [usd removeObjectForKey:@"payViaCreditCard"]; selectedCardID = nil; [[CreditCardManager sharedCreditCardManager] removeCreditCard:creditCardToDelete]; [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade]; [self.tableView reloadData];

最后，我的用户界面没有更新并且应用程序冻结，当我重新启动应用程序时，NSUserDefaults中的数据已更改.

In the end my UI not updating and app freezes, when I relaunch the app the data in NSUserDefaults changed.

推荐答案

如果您执行deleteRowsAtIndexPaths:withRowAnimation或tableView reloadData，那会很好.

It would be good if you do either deleteRowsAtIndexPaths:withRowAnimation or tableView reloadData.

[[CreditCardManager sharedCreditCardManager] removeCreditCard:creditCardToDelete]; [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade]; OR [[CreditCardManager sharedCreditCardManager] removeCreditCard:creditCardToDelete]; [self.tableView reloadData];
