是否有可能有一个UITableView细胞不同的高度，当我使用的显示单元的几种不同的方式？ [英] Is it possible to have differing heights in a UITableView Cell when I use several different ways of displaying the cell?
问题描述
我花了好几天试图弄清楚这一点，但似乎没有成为一个解决方案。我有它两个标签一个非常基本的UITableView单元。其中一人将是一条线，第二个为多。第二个将在高度是变化的。这里是什么我试图制造（UIStackViews内部UITableViewCells）的一个例子：
I've spent several days trying to figure this out, but there doesn't seem to be a solution. I have a very basic UITableView cell with two labels in it. One of them will be one line, the second will be multiline. The second one will be varying in heights. Here is an example of what I'm trying to produce ( UIStackViews inside of UITableViewCells ) :

从阅读数百SO帖子，数百名博客，精练的苹果开发者网站，似乎是一种方式可以写一个无限量的。数百个不同的方式尝试有后，我仍然无法管理要显示的文本，像这样。我觉得有些麻烦来自于一个事实，我使用的 3 在一个不同的UITableView细胞的UITableView变化。
From reading hundreds of SO posts, hundreds of blogs, scouring the Apple Developer sites, there seems to be an unlimited amount of ways one could write this. After having experimented with hundreds of different ways, I still can't manage to display the text like so. I think some of the trouble comes from the fact that I'm using 3 different UITableView cell variations in one UITableView.
下面是我的code从我的最新尝试的cellForRowAtIndexPath ：
Here is my code from my latest attempt cellForRowAtIndexPath :
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell : UITableViewCell!
let (parent, isParentCell) = self.findParent(indexPath.row)
if !isParentCell {
let categories = ["words", "translation","commentary"]
if categories[parent] == "words" {
cell = tableView.dequeueReusableCellWithIdentifier(childWordsCellIdentifier, forIndexPath: indexPath) as UITableViewCell
// Reset content
for subview in cell.contentView.subviews {
subview.removeFromSuperview()
}
cell.prepareForReuse()
let words = self.page.valueForKey("words")!.allObjects as! [Word]
let wordsInOrder = words.sort({Int($0.order!) < Int($1.order!) })
let word = wordsInOrder[indexPath.row - 1]
let labelWidth = (self.view.frame.width - 80) / 2
let wordLabel = UILabel(frame: CGRectZero)
wordLabel.text = word.valueForKey("sanskrit") as? String
wordLabel.font = UIFont(name: "EuphemiaUCAS-Bold", size: 16)
wordLabel.numberOfLines = 0
wordLabel.translatesAutoresizingMaskIntoConstraints = false
wordLabel.layer.borderColor = UIColor.greenColor().CGColor
wordLabel.layer.borderWidth = 1.0
let widthWordConstraint = wordLabel.widthAnchor.constraintEqualToConstant(labelWidth)
widthWordConstraint.priority = 300
widthWordConstraint.active = true
let englishWordLabel = UILabel(frame: CGRectZero)
englishWordLabel.text = "Foobar don't want to play my game with my anymore."
englishWordLabel.font = UIFont(name: "STHeitiTC-Light", size: 16)
englishWordLabel.numberOfLines = 0
englishWordLabel.preferredMaxLayoutWidth = labelWidth
englishWordLabel.translatesAutoresizingMaskIntoConstraints = false
let englishWordConstraint = englishWordLabel.widthAnchor.constraintEqualToConstant(labelWidth)
englishWordConstraint.priority = 300
englishWordConstraint.active = true
englishWordLabel.layer.borderColor = UIColor.blueColor().CGColor
englishWordLabel.layer.borderWidth = 1.0
let stackView = UIStackView()
stackView.axis = .Horizontal
stackView.distribution = .FillProportionally
stackView.alignment = .FirstBaseline
stackView.spacing = 15
stackView.layoutMargins = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 20)
stackView.layoutMarginsRelativeArrangement = true
stackView.addArrangedSubview(wordLabel)
stackView.addArrangedSubview(englishWordLabel)
stackView.translatesAutoresizingMaskIntoConstraints = false
englishWordLabel.topAnchor.constraintEqualToAnchor(stackView.topAnchor).active = true
englishWordLabel.bottomAnchor.constraintEqualToAnchor(stackView.bottomAnchor).active = true
cell.contentView.addSubview(stackView)
cell.contentView.layoutIfNeeded()
} else {
cell = tableView.dequeueReusableCellWithIdentifier(childCellIdentifier, forIndexPath: indexPath) as UITableViewCell
// Reset content
cell.textLabel!.text = ""
for subview in cell.contentView.subviews {
subview.removeFromSuperview()
}
cell.prepareForReuse()
cell.textLabel!.text = self.page.valueForKey(categories[parent]) as? String
cell.textLabel!.textColor = UIColor(red: 35/255.0, green: 31/255.0, blue: 32/255.0, alpha: 1.0)
cell.textLabel!.font = UIFont(name: "STHeitiTC-Light", size: 16)
}
}
else {
// Parent
cell = tableView.dequeueReusableCellWithIdentifier(parentCellIdentifier, forIndexPath: indexPath)
cell.textLabel!.text = self.dataSource[parent].title
cell.textLabel!.textColor = UIColor(red: 66/255.0, green: 116/255.0, blue: 185/255.0, alpha: 1.0)
cell.textLabel!.font = UIFont(name: "STHeitiTC-Light", size: 20)
}
cell.selectionStyle = .None
cell.textLabel!.translatesAutoresizingMaskIntoConstraints = false
cell.textLabel!.numberOfLines = 0
cell.textLabel!.lineBreakMode = .ByWordWrapping
return cell
}
这会产生这样的：

推荐答案
表视图单元格的HIGHT是根据的rowHeight 属性，或者在桌子上决定可选FUNC的tableView的返回值（_的tableView：UITableView的，heightForRowAtIndexPath indexPath：NSIndexPath） - GT; CGFloat的从表视图委托。
The hight of a table view cell is decided by the table based on the rowHeight property, or on the return value of optional func tableView(_ tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat from the table view delegate.
这可以由程序员为的UITableViewCell通过它的框架属性进行设置的HIGHT被忽略！
The hight that may be set by the programmer for the UITableViewCell through it's frame property is ignored!
因此，您需要编程计算出每个单元的预期HIGHT。然后，你需要实施可选FUNC的tableView（_的tableView：UITableView的，heightForRowAtIndexPath indexPath：NSIndexPath） - GT; CGFloat的从每个细胞的表视图代表
Hence you need to figure out the desired hight of each cell programatically. Then you need to implement optional func tableView(_ tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat from the table view delegate for each of the cells.
如果一个单元格的大小变化而显示的表视图，您需要为：
If the size of a cell changes while the table view is displayed, you need to either:
- 重新装入表
reloadData（）从的UITableView或 - 更新
FUNC reloadRowsAtIndexPaths细胞（_ indexPaths：[NSIndexPath]，withRowAnimation动画：UITableViewRowAnimation）从的UITableView
- reload the table with
reloadData()fromUITableView, or - update the cell with
func reloadRowsAtIndexPaths(_ indexPaths: [NSIndexPath], withRowAnimation animation: UITableViewRowAnimation)fromUITableView.
修改
事实上，因为你正在使用的限制在你认为它应该在不使用``工作。
Actually since you are using constraints in you view it should work without using ``.
尝试更换code在如果类别[家长] ==改为{..} 与
cell = tableView.dequeueReusableCellWithIdentifier(childWordsCellIdentifier, forIndexPath: indexPath) as UITableViewCell
// Reset content
for subview in cell.contentView.subviews {
subview.removeFromSuperview()
}
cell.prepareForReuse()
let words = self.page.valueForKey("words")!.allObjects as! [Word]
let wordsInOrder = words.sort({Int($0.order!) < Int($1.order!) })
let word = wordsInOrder[indexPath.row - 1]
let wordLabel = UILabel(frame: CGRectZero)
wordLabel.text = word.valueForKey("sanskrit") as? String
wordLabel.font = UIFont(name: "EuphemiaUCAS-Bold", size: 16)
wordLabel.numberOfLines = 0
wordLabel.translatesAutoresizingMaskIntoConstraints = false
wordLabel.layer.borderColor = UIColor.greenColor().CGColor
wordLabel.layer.borderWidth = 1.0
let englishWordLabel = UILabel(frame: CGRectZero)
englishWordLabel.text = "Foobar don't want to play my game with my anymore."
englishWordLabel.font = UIFont(name: "STHeitiTC-Light", size: 16)
englishWordLabel.numberOfLines = 0
let stackView = UIStackView()
stackView.axis = .Horizontal
stackView.distribution = .FillProportionally
stackView.alignment = .Fill // EDIT
stackView.spacing = 15
stackView.layoutMargins = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 20)
stackView.layoutMarginsRelativeArrangement = true
stackView.addArrangedSubview(wordLabel)
stackView.addArrangedSubview(englishWordLabel)
stackView.translatesAutoresizingMaskIntoConstraints = false
cell.contentView.addSubview(stackView)
cell.contentView.leadingAnchor.constraintEqualToAnchor(stackView.leadingAnchor).active = true
cell.contentView.topAnchor.constraintEqualToAnchor(stackView.topAnchor).active = true
cell.contentView.trailingAnchor.constraintEqualToAnchor(stackView.trailingAnchor).active = true
cell.contentView.bottomAnchor.constraintEqualToAnchor(stackView.bottomAnchor).active = true
cell.contentView.layoutIfNeeded()
此外，我会用不同的细胞类这一任务而不是删除的内容查看的意见。
Also I would have used to different cells classes for this task rather than removing the views in the contentView.
