私は5つのセクションを持っています。セクション 0 を通過した後、cellForRowAtIndex がセクション 1 をループし続ける理由がわかりません。以下にコードとログを示します。ありがとう

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    numberOfSections = 0;

    if ([pastSevenDayArray count] > 0) numberOfSections++;
    if ([pastFourteenDaysArray count] > 0) numberOfSections++;
    if ([pastThirtyDaysArray count] > 0) numberOfSections++;
    if ([pastSixtyDaysArray count] > 0) numberOfSections++;
    if ([pastNinteyDaysArray count] > 0) numberOfSections++;
    if ([pastArray count] > 0) numberOfSections++;

    NSLog (@"numberofSections %i", numberOfSections);

    [self numberOfCells];

    return numberOfSections;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    if (section == 0)
    {
        return sectionZeroCellCount;
    }

    else if (section == 1)
    {
        return sectionOneCellCount;
    }
    else if (section == 2)
    {
        return sectionTwoCellCount;
    }
    else if (section == 3)
    {
        return sectionThreeCellCount;
    }
    else if (section == 4)
    {
        return sectionFourCellCount;
    }
    if (section == 5)
    {
        return sectionFiveCellCount;
    }
}

あなたが変わるなら、私は信じています：

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

に：

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

セルの indexPath も指定する必要があると思わない限り、機能します。
