Delete row from table and sqlite database

Question

I still need your help.
I have this piece of code that doesn\'t want to work.

-(void)tableView:(UITableView *)_tableView commitEditingStyle:(UITableViewCellE         


        

Answer 1

You might want to swap around

[tableView reloadData];
[tableView endUpdates];

to make it

[tableView endUpdates];
[tableView reloadData];

Alternatively please tell us what the error message for the SIGABRT is.

Answer 2

i hope shoppingListItems array contains Dictinaries . so have that Object In Array u can Directly Delete that particular object From Array. TRY LIKE THIS.....

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

if (editingStyle == UITableViewCellEditingStyleDelete) {

    NSDictionary *rowVals = (NSDictionary *) [shoppingListItems objectAtIndex:indexPath.row];
    NSString *keyValue = (NSString *) [rowVals objectForKey:@"key"];
    sqlite3 *db;
    int dbrc; //Codice di ritorno del database (database return code)
    DatabaseShoppingListAppDelegate *appDelegate = (DatabaseShoppingListAppDelegate*) [UIApplication sharedApplication].delegate;
    const char *dbFilePathUTF8 = [appDelegate.dbFilePath UTF8String];
    dbrc = sqlite3_open(dbFilePathUTF8, &db);
    if (dbrc) {
        NSLog(@"Impossibile aprire il Database!");
        return;
    }

    sqlite3_stmt *dbps; //Istruzione di preparazione del database

    NSString *deleteStatementsNS = [NSString stringWithFormat: @"DELETE FROM \"shoppinglist\" WHERE key='%@'", keyValue];
    const char *deleteStatement = [deleteStatementsNS UTF8String];
    dbrc = sqlite3_prepare_v2(db, deleteStatement, -1, &dbps, NULL);
    dbrc = sqlite3_step(dbps);


    //faccio pulizia rilasciando i database
    sqlite3_finalize(dbps);
    sqlite3_close(db);
    [shoppingListItems removeObjectAtIndex:indexPath.row];
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

    [tableView reloadData];
}
}
