Question

我在UIViewController中有一个tableview，我想删除tableview的一行并更新一个sqlite db。在删除单元格的边缘时，我的应用程序会随机终止。

以下是相关代码：

NSMutableArray * FeedArr;
NSString *query,*sid;
sid=[[FeedArr objectAtIndex:indexPath.row]objectForKey:@"feedId"];
DB *dbobj=[[DB alloc]init];
query=@"DELETE FROM FEED_MASTER WHERE feedId=?";
[dbobj deleteFromDatabase:sid Query:query];

query=@"DELETE FROM ITEMS_MASTER WHERE feedId=?";
[dbobj deleteFromDatabase:sid Query:query];

[FeedArr removeObjectAtIndex:indexPath.row];

[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
 withRowAnimation:UITableViewRowAnimationFade];

能帮助我吗？

提前致谢....

这是我的代码

NSMutableArray * FeedArr; NSString * query，* sid; sid = [[FeedArr objectAtIndex：indexPath.row] objectForKey：@“feedId”]; DB * dbobj = [[DB alloc] init]; query = @“DELETE FROM FEED_MASTER WHERE feedId =？”; [dbobj deleteFromDatabase：sid查询：查询];

        query=@"DELETE FROM ITEMS_MASTER WHERE feedId=?";
        [dbobj deleteFromDatabase:sid Query:query];

        [FeedArr removeObjectAtIndex:indexPath.row];

        [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
         withRowAnimation:UITableViewRowAnimationFade];

删除UIViewController中的行
