这是glitch。正如您所看到的那样，当我将自定义UITableViewCell SummaryCell推出应用视图时，单元格会出现故障并且不会将UILabels dayOfTheWeek和totalAmountSpent放在适当的位置。但如果你点击毛刺细胞，它会恢复正常。
以下是我用于创建自定义单元格UITableViewController SummaryTableViewController的{{1}}的一些方法：
summaryCell这是the nib file & its constraints，对应于我的自定义override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//Create day of week cell
let cell = tableView.dequeueReusableCellWithIdentifier("summaryCell", forIndexPath: indexPath) as! SummaryCell
let day = dayOfWeek[indexPath.row]
let height = CGFloat(55)
let dayOfWeekWidth = CGFloat(80)
cell.dayOfWeek.text = day.rawValue.uppercaseString
cell.dayOfWeek.frame = CGRectMake(0, 0, dayOfWeekWidth, height)
cell.dayOfWeek.backgroundColor = colorOfDay[day]
cell.totalAmountSpent.text = "$\(totalSpentPerDay[indexPath.row])"
cell.totalAmountSpent.frame = CGRectMake(cell.dayOfWeek.frame.maxX + 1, 0, view.bounds.width - dayOfWeekWidth, height)
cell.totalAmountSpent.backgroundColor = colorOfDay[day]
cell.totalAmountSpentView.backgroundColor = colorOfDay[day]
cell.heightOfMainView.constant = normalCellHeight
//^I have this to make sure the height of the cell is the same as
//the height of the mainView in the nib file `summaryCell` so that
//when the table loads intially, only the mainView of the `summaryCell` shows up.
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if expandedCellPaths.contains(indexPath){
let index = expandedCellPaths.indexOf(indexPath)
expandedCellPaths.removeAtIndex(index!)
}else{
expandedCellPaths.append(indexPath)
}
//old trick to animate cell expand/collapse
tableView.beginUpdates()
tableView.endUpdates()
}
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
let expandedCellHeight = normalCellHeight*2
if expandedCellPaths.contains(indexPath){
return expandedCellHeight
}else{
return normalCellHeight
}
}
我最好猜测为什么会发生这种情况（1）我的nib文件UITableViewCell SummaryCell或（2）中的约束summaryCell：
如果有人能告诉我如何解决这个故障，我们将不胜感激！ tableView.beginUpdates（） tableView.endUpdates（）
答案 0 :(得分：0)
其实没关系！我意识到自己的错误！我只需要在tableView(:cellForRowAtIndexPath:)中删除这些行：
let height = CGFloat(55)
let dayOfWeekWidth = CGFloat(80)
cell.dayOfWeek.frame = CGRectMake(0, 0, dayOfWeekWidth, height)
cell.totalAmountSpent.frame = CGRectMake(cell.dayOfWeek.frame.maxX + 1, 0, view.bounds.width - dayOfWeekWidth, height)
