Question

我正在使用parse.com作为数据库。我的tableViewController，它是一个类PFQueryTableViewController，如下所示：

// Override to customize what kind of query to perform on the class. The default is to query for
// all objects ordered by createdAt descending.
- (PFQuery *)queryForTable {
    PFQuery *exerciciosQuery = [PFQuery queryWithClassName:self.parseClassName];
    [exerciciosQuery includeKey:@"exercicios"];
    [exerciciosQuery findObjects];
    _exerciciosArray = [exerciciosQuery findObjects];
    NSLog(@"teste %@", _exerciciosArray);

    // If no objects are loaded in memory, we look to the cache first to fill the table
    // and then subsequently do a query against the network.
    if ([self.objects count] == 5) {
        exerciciosQuery.cachePolicy = kPFCachePolicyCacheThenNetwork;
    }

    return exerciciosQuery;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath   *)indexPath object:(PFObject *)object {
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }

    // Configure the cell
    PFObject *exercicios = [_exerciciosArray objectAtIndex:indexPath.row];
    [cell.textLabel setText:[exercicios objectForKey:@"Title"]];

    return cell;
}

我的桌子没有显示任何内容。当我记录_exerciciosArray时，它看起来像这样：

{\ n cep = \“25553-555 \”; \ n cidade = \“Rio de Janeiro \”; \ n email = \“blabla@globo.com \”; \ n endereco = \“Rua Oscar 100/500 \“; \ n \ n \ testado \ \”里约热内卢\“; \ n exercicio1 = \”\“; \ n exercicios =（\ n \”{\ n Title = \\“Rosca no Pulley \\” ; \ n} \“，\ n \”{\ n标题= \\“Rosca no Pulley \\”; \ n} \“\ n）; \ n nascimento = \”12/02/1888 \“; \ n nome = Jorge; \ n pais = Brasil; \ n sobrenome = Junior; \ n telefone = \“（21）9999-9999 \”; \ n username = \“blabla@globo.com \”; \ n}“

如果您正在使用PFQueryTableViewController，则不需要执行findObjects queryForTable会自动将每个对象发送到- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {，因此您不需要PFObject *exercicios = [_exerciciosArray objectAtIndex:indexPath.row];已经在方法中接收PFObject。

只是做：

[cell.textLabel setText:[object objectForKey:@"Title"]];

并从此queryForTable中删除：

[exerciciosQuery findObjects];
_exerciciosArray = [exerciciosQuery findObjects];
