Swift xcode 6：滚动动态表超出范围时字体大小发生变化

当行滚动出视图时，使用动态表的ViewController中TextView的字体大小会发生变化。静态表不会发生这种情况。脚本中的字体大小设置正确

我必须在自定义类中显式更改字体大小吗

以下是一些代码（按照@neo的要求）：

另一篇帖子指出，通过选择UITextView，问题得以解决。这对我有用

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> CREWBasicSuppliesCell {
    let cell = tableView.dequeueReusableCellWithIdentifier(cellName) as! CREWBasicSuppliesCell
    //        NSLog("section %d", indexPath.section)
    if indexPath.section == 1 {
        var row = 0
        row = indexPath.row
        var fetchRequest = NSFetchRequest(entityName: "Switch")
        var predicate = NSPredicate(format: "(viewName = %@)",viewName)
        fetchRequest.predicate = predicate
        // Execute the fetch request
        var error: NSError? = nil
        if var fetchResults = managedObjectContext?.executeFetchRequest(fetchRequest, error: &error) as? [Switch] {
            var recordCount = 0
            recordCount = fetchResults.count
            if recordCount > 0 {
                var appConfig  = fetchResults [row]
                cell.mySwitch.on = appConfig.switchValue.boolValue
                cell.myTextView.text = appConfig.switchDescription
            }
        }
     } else { // section 0
        cell.mySwitch.hidden = true
        var fetchRequest = NSFetchRequest(entityName: "View")
        var predicate = NSPredicate(format: "(viewName = %@)",viewName)
        fetchRequest.predicate = predicate
        // Execute the fetch request
        var error: NSError? = nil
        if var fetchResults = managedObjectContext?.executeFetchRequest(fetchRequest, error: &error) as? [View] {
            var row = 0
            row = indexPath.row
            var recordCount = 0
            recordCount = fetchResults.count
            if recordCount > 0 {
                var appConfigView  = fetchResults [row]
                cell.myTextView.text = appConfigView.viewDescription
            }
        }
    }
    //        NSLog("section %d", indexPath.section)
    return cell
}
