核心數據單元未正確更新

Question

我在創建的UITableViewCell中顯示數據時遇到問題。

我有一個CoreData模型，我有一個自定義Cell，我從Xib加載。佈局加載正確，並生成正確數量的單元格。更新button.titleLabel.text和說明時出現問題。

這是我的UITableView和UITableViewCell的相關代碼：

#pragma mark - UITableViewDatasource Methods. 
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    return [pointsHistoryItems count]; 
} 

// Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier: 
// Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls) 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    NSString *CellIdentifier = [NSString stringWithFormat:@"Cell%d",indexPath.row]; 
    PointsHistoryItemCell* cell = (PointsHistoryItemCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    return [self createCustomCell:cell cellForRowAtIndexPath:indexPath]; 
} 

- (PointsHistoryItemCell *)createCustomCell:(PointsHistoryItemCell *)cell cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    if (cell == nil) 
    { 
     cell = (PointsHistoryItemCell *)[[[NSBundle mainBundle] loadNibNamed:@"PointsHistoryItemCell" owner:self options:nil] objectAtIndex:0]; 
    } 

    AwesomePointsHistoryItem *aphi = (AwesomePointsHistoryItem *)[pointsHistoryItems objectAtIndex:indexPath.row]; 

    cell.description.text = aphi.description; 

    NSString* pointsText = [NSString stringWithFormat:@"%@ Points", [aphi.points stringValue]]; 
    [cell.button.titleLabel setText:pointsText]; 


    NSLog(@"is reaching createCustomCell"); 
    NSLog(@"points %@", cell.button.titleLabel.text); 

    return cell; 
} 

日誌打印：

is reaching createCustomCell 
points 600 Points 

不過。該cell.button.titleLabel.text不更新！

我在做什麼錯？使用

Answer 1

[cell.button setTitle: pointsText forState: UIControlStateNormal]; 

代替

[cell.button.titleLabel setText:pointsText]; 

注：希望cell.button是UIButton
