Allright, I think I've read all the issues which seemed to be the same as I did.
I have a UITextView in a UITableViewCell, the cell itself contains an imageView, a UILabel as title, the UITextView and another UILabel.
Screenshot:
I believe the constraints to be correct. Currently the view does an estimate which is correct in most cases, but in my case the content is larger than the UITableViewCell's height, this is probably due to the delayed rendering of the UITableViewCell, causing other list items to draw behind this one (it only appears on top).
The code which estimates the height:
func heightForCellAtIndexPath(indexPath:NSIndexPath) -> CGFloat {
if (calculatorCell[cellIdentifier] == nil) {
calculatorCell[cellIdentifier] = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? UITableViewCell
}
if let cell = calculatorCell[cellIdentifier] {
populateCell(cell, indexPath: indexPath)
cell.setNeedsLayout()
cell.layoutIfNeeded()
return cell.contentView.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize).height
}
ErrorClass.log("Could not instantiate cell? returning 100 float value instead for listView")
return 100.0
}
This is a generic function as you see since it's handling a UITableViewCell not a custom, so the populateCell in this case, the first index returns the cell with the issue, the rest are comments which are working fine, I'm just sharing it all since people will ask for it:
if (indexPath.row == 0) {
let cellUnwrapped = cell as! ChallengeHeader
cellUnwrapped.setContent(
challenge!.content,
date: StrFormat.deadLineFromDate(challenge!.endAt),
likes: Language.countValue("challenge_count_like", count: challenge!.totalLikes),
likeController: self,
commentCount: Language.countValue("global_count_comment", count: challenge!.totalComments)
)
cellUnwrapped.like(userLiked)
cellUnwrapped.loadAttachments(challenge!.attachments)
return cellUnwrapped
} else {
let cellUnwrapped = cell as! ListItemComment
let challengeComment = items[(indexPath.row - 1)] as! ChallengeComment
var username = "Anonymous"
if let user = challengeComment.author as User? {
cellUnwrapped.iconLoad(user.avatar)
username = user.displayName
}
cellUnwrapped.setContentValues(
StrFormat.cleanHtml(challengeComment.text),
date: StrFormat.dateToShort(challengeComment.createdAt),
username: username
)
return cellUnwrapped
}
The cell's setContentvalues which parses the html string to NSAttributedString, it's wrapped in an if to prevent reloads to re-render the NSAttributedString. It won't change but it does take a while to render:
func setContent(content:String, date:String, likes:String, likeController : LikeController, commentCount:String) {
if (content != txtContent) {
self.contentLabel.text = nil
self.contentLabel.font = nil
self.contentLabel.textColor = nil
self.contentLabel.textAlignment = NSTextAlignment.Left
contentLabel.attributedText = StrFormat.fromHtml(content)
txtContent = content
}
deadlineLabel.text = date
likesLabel.text = likes
self.likeController = likeController
likeButton.addTarget(self, action: "likeClicked:", forControlEvents: .TouchUpInside)
totalComments.text = commentCount
totalComments.textColor = StyleClass.getColor("primaryColor")
doLikeLayout()
}
So TL;DR; I have a UITextView inside a UITableViewCell scaling sizes using autolayout and containing an NSAttributedString to parse html and html links. How come it does not render well, and how to fix it?

I'm writing a demo to show user's tweets.
The question is:
Every time I scroll to the bottom and then scroll back, the tweet's images and comments are reloaded, even the style became mess up. I know it something do with dequeue, I set Images(which is an array of UIImageView) to [] every time after dequeue, but it is not working. I'm confused and couldn't quite sleep....
Here is core code of my TableCell(property and Images set), which provide layout:
class WechatMomentListCell: UITableViewCell{
static let identifier = "WechatMomentListCell"
var content = UILabel()
var senderAvatar = UIImageView()
var senderNick = UILabel()
var images = [UIImageView()]
var comments = [UILabel()]
override func layoutSubviews() {
//there is part of Image set and comments
if images.count != 0 {
switch images.count{
case 1:
contentView.addSubview(images[0])
images[0].snp.makeConstraints{ (make) in
make.leading.equalTo(senderNick.snp.leading)
make.top.equalTo(content.snp.bottom)
make.width.equalTo(180)
make.height.equalTo(180)
}
default:
for index in 0...images.count-1 {
contentView.addSubview(images[index])
images[index].snp.makeConstraints{ (make) in
make.leading.equalTo(senderNick.snp.leading).inset(((index-1)%3)*109)
make.top.equalTo(content.snp.bottom).offset(((index-1)/3)*109)
make.width.equalTo(90)
make.height.equalTo(90)
}
}
}
}
if comments.count != 0, comments.count != 1 {
for index in 1...comments.count-1 {
comments[index].backgroundColor = UIColor.gray
contentView.addSubview(comments[index])
comments[index].snp.makeConstraints{(make) in
make.leading.equalTo(senderNick)
make.bottom.equalToSuperview().inset(index*20)
make.width.equalTo(318)
make.height.equalTo(20)
}
}
}
}
Here is my ViewController, which provide datasource:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let tweetCell = tableView.dequeueReusableCell(withIdentifier: WechatMomentListCell.identifier, for: indexPath) as? WechatMomentListCell else {
fatalError("there is no WechatMomentList")
}
let tweet = viewModel.tweetList?[indexPath.row]
for i in tweet?.images ?? [] {
let flagImage = UIImageView()
flagImage.sd_setImage(with: URL(string: i.url))
tweetCell.images.append(flagImage)
}
for i in tweet?.comments ?? [] {
let flagComment = UILabel()
flagComment.text = "\(i.sender.nick) : \(i.content)"
tweetCell.comments.append(flagComment)
}
return tweetCell
}
The Images GET request has been define at ViewModel using Alamofire.
The firsttime is correct. However, If I scroll the screen, the comments will load again and images were mess up like this.
I found the problem in your tableview cell. in cell you have two variables like this.
var images = [UIImageView()]
var comments = [UILabel()]
Every time you using this cell images and comments are getting appended. make sure you reset these arrays every time you use this cell. like setting theme empty at initialization.
I tried to copy only the necessary code to show my problem. I have a tableview with dynamic content. I created a prototype cell and it has a user name and 10 stars (it's a rating page). People in the group are allowed to rate other people. Everything is working ok, but I have a problem when I scroll down. If I rate my first user with 8 stars, when I scroll down then some user that was in the bottom area of the tableview, appears with the rate that I gave to my first user. I know that tableview reuse cells. I tried many things but with no success. Hope someone can help me on that.
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let model = users[indexPath.row]
let cell = tableView.dequeueReusableCellWithIdentifier("RatingCell") as! RatingTableViewCell
cell.tag = indexPath.row
cell.playerLabel.text = model.name
cell.averageView.layer.borderWidth = 1
cell.averageView.layer.borderColor = Color.Gray1.CGColor
cell.averageView.layer.cornerRadius = 5
cell.starsView.userInteractionEnabled = true
cell.averageLabel.text = "\(user.grade)"
for i in 0...9 {
let star = cell.starsView.subviews[i] as! UIImageView
star.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(starTap)))
star.userInteractionEnabled = true
star.tag = i
star.image = UIImage(named: (i + 1 <= grade ? "star-selected" : "star-empty"))
}
return cell
}
func changeRating(sender: UIImageView) {
let selectedStarIndex = sender.tag
let cell = sender.superview?.superview?.superview as! RatingTableViewCell
let model = users[cell.tag]
let stars = sender.superview?.subviews as! [UIImageView]
cell.averageLabel.text = "\(selectedStarIndex + 1)"
for i in 0...9 {
let imgName = i <= selectedStarIndex ? "star-selected" : "star-empty"
stars[i].image = UIImage(named: imgName)
}
}
func starTap(gesture: UITapGestureRecognizer) {
changeRating(gesture.view as! UIImageView)
}
The way to solve this problem is by updating the model that holds all the information for the uitableviewcell. Whenever a rating is updated fora particular cell, make sure you reflect that update in the respective object / dictionary in an array. Furthermore, if you have a customuitableviewcell, it might be a good idea to reset the stars in the "prepareForUse" function, so that way when a cell is reused it doesn't use old data.
In your comments, you said that you have an array with selected rates.But you did not show that in your code.
In my opinion, you need record indexPath too, because indexPath.row is binding with your rate data(may be grade?).The best way to do so is that #Jay described up.And you should not write the code of configuring cell data and cell's logic in your view controller.If your business logic is complex, you will find that it is a nightmare.^=^
I am having some serious trouble getting my multiline label to show all of its lines. Often, the last line of the label simply does not appear, but it is apparent that the dynamically calculated cell height has taken in to account that it should have appeared, leaving around the appropriate amount of white space left over in my cell.
The affected label can display 1-7 lines depending on the data. I have played around with many various constraints to try and get it to display but regardless of what is on the last line, it just won't display.
The weird thing is, sometimes it will display when I segue in to the VC, but then when I use the segmented controller inside the VC to display different data and then go back again, the last line will again not display. The opposite happens frequently too (last line of label cutting off when I segue in to the VC, but then using the segmented controller inside the VC to change the displayed data and then go back, it will then display fine).
Things I have ensured: The label is set to word wrap, has line count of 0, has a height greater than or equal to the height of one of it's lines, its resistance and vertical content hugging is set to the highest of anything in the cell, and the width is set appropriately.
The below code is how I determine how many lines the label will have:
let descString = NSMutableAttributedString()
let bountyStart = NSMutableAttributedString(string: "Bounty: ", attributes: [NSFontAttributeName : UIFont.boldSystemFontOfSize(15)])
let bountyDesc = NSMutableAttributedString(string: bounty.description)
descString.appendAttributedString(bountyStart)
descString.appendAttributedString(bountyDesc)
let bLine = NSMutableAttributedString(string: "\n\n", attributes: [NSFontAttributeName : UIFont.systemFontOfSize(2)])
descString.appendAttributedString(bLine)
if !(bounty.turtles == 0.0){
let turtleStart = NSMutableAttributedString(string: "Your turtle count: ")
let turtleAmount = NSMutableAttributedString(string: bounty.turtleCount.description)
descString.appendAttributedString(turtleStart)
descString.appendAttributedString(turtleAmount)
}
descriptionLabel.attributedText = descString
In the screen shot below, you can see that the height of the cell is being calculated appropriately but for some reason, the last line of the label just refuses to show. It should appear after the "is for noobs" line. I've manipulated the white space to appear after the line instead of elsewhere by setting the problem labels bottom to constraint to be greater than or equal, and all other top to bottom constraints as equal to.
Constraints of the problem label:
I've been stumped for quite a while on this one, and I'm starting to think it's not the constraints I've set but something much deeper. All though I would love to be proven wrong.

This seems like a IB thing, very likely constraints.
Make sure that any component's top constraint placed under this multiline UILabel is set to the bottom of said UILabel.
For example, in this project of mine, both the TitleView and TimeAndDetailsView contain UILabels that span multiplelines. In order to allow autolayout to properly space things all constraints need to be in order, also notice how the top constraint of TimeAndDetails is the bottom of TitleView
Edit note:
Before you tableView.reloadData() type the following 2 lines, or if uncertain, put it inside viewDidLoad
tableView.estimatedRowHeight = 60 //Type your cell estimated height
tableView.rowHeight = UITableViewAutomaticDimensionhere
Went to sleep last night, ok so I decided to add your code to my details label from the storyboards picture I had posted before, and it seems to have displayed just fine. I have a few questions and pointers below.
let descString = NSMutableAttributedString()
let bountyStart = NSMutableAttributedString(string: "Bounty: ", attributes: [NSFontAttributeName : UIFont.boldSystemFontOfSize(15)])
let bountyDesc = NSMutableAttributedString(string: "this would be 'bounty.description and is set to size 40", attributes: [NSFontAttributeName : UIFont.boldSystemFontOfSize(40)])
descString.appendAttributedString(bountyStart)
descString.appendAttributedString(bountyDesc)
let bLine = NSMutableAttributedString(string: "\n\n", attributes: [NSFontAttributeName : UIFont.systemFontOfSize(10)])
descString.appendAttributedString(bLine)
let turtleStart = NSMutableAttributedString(string: "Your turtle count: ")
let turtleAmount = NSMutableAttributedString(string: "random number 1234 goes here")
descString.appendAttributedString(turtleStart)
descString.appendAttributedString(turtleAmount)
detailsLabel.attributedText = descString
Sadly, this is in a scrollview and not in a cell, so there is the first difference. My first question; is your descriptionLabel.attributedText supposed to display different fontscolors or fonttypes/sizes?, if not then I would say to just use descriptionLabel.text instead of descriptionLabel.attributedText.
Now the fact that there is white space but nothing showing us makes me wonder if bounty.turtleCount.description was previously set to color white somewhere else, or you are simply seeing the newlines you added \n\n and nothing is there because if !(bounty.turtles == 0.0) doesnt execute. Are you sure the that if statement is executed? place a breakpoint and follow along to make sure the values are appended to descString
If this is all correct, then my guess would still be on constraints.
Could you elaborate on, quote from you; "sometimes it will display when I segue in to the VC, but then when I use the segmented controller inside the VC to display different data and then go back again, the last line will again not display." what are you doing different in the seg control when loading the values and reloading the tableview that makes it not display, and under what conditions does it work properly when you segue.
I updated xcode and now this doesn't happen anymore.
I am having a problem creating UILabels to insert into my tableview cells. They insert fine and display fine, the problem comes in when I go to scroll. The ordering of the row's goes haywire and looses it's initial order. For instance, at the beginning, the idLabel's cell text, goes from 0 > 14, in sequential order. After scrolling down and back up, the order could be anything, 5, 0, 10, 3 etc.
Any ideas on why this is happening? I am presuming my attempts to update the label's after cell creation is wrong.
var idArr: NSMutableArray!
// In init function
self.idArr = NSMutableArray()
for ind in 0...14 {
self.idArr[ind] = ind
}
// Create the tableview cells
internal func tableView( tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath ) -> UITableViewCell {
if cell == nil {
let id = self.idArr[indexPath.row] as Int
cell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "cell" )
// Id
let idLabel: UILabel = UILabel( frame: CGRectZero )
idLabel.text = String( id )
idLabel.textColor = UIColor.blackColor()
idLabel.tag = indexPath.row
idLabel.sizeToFit()
idLabel.layer.anchorPoint = CGPointMake( 0, 0 )
idLabel.layer.position.x = 15
idLabel.layer.position.y = 10
idLabel.textAlignment = NSTextAlignment.Center
cell?.addSubview( idLabel )
}
// Update any labels text string
for obj: AnyObject in cell!.subviews {
if var view = obj as? UILabel {
if view.isKindOfClass( UILabel ) {
if view.tag == indexPath.row {
view.text = String( id )
}
}
}
}
// Return the cell
return cell!
}
Thanks for any assistance, I can't see the wood for the trees anymore.
The logic in your cell updating looks off. You are checking that a tag you set at initialization is equal to the index path's row but because the cells should be reused this will not always be the case. If you just remove that tag checking line in the for loop it should work fine.
Also, I'm not sure why you are checking ifKindOfClass after you have optionally cast the view as a label anyway.
To prevent accidentally updating Apple's views you would be better off adding a constant tag for the label and pulling the label by that tag instead of looping through all of the subviews.
This is clearly not the actual code you are running since the id variable is not in the proper scope and there is no definition of cell. I've added proper dequeueing and move the id variable to something that works. I'm assuming you are doing those in your actual code.
internal func tableView( tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath ) -> UITableViewCell {
let labelTag = 2500
let id = self.idArr[indexPath.row] as Int
var cell = tableView.dequeueReusableCellWithIdentifier("cell")
if cell == nil {
cell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "cell" )
// Id
let idLabel: UILabel = UILabel( frame: CGRectZero )
idLabel.text = String( id )
idLabel.textColor = UIColor.blackColor()
idLabel.tag = labelTag
idLabel.sizeToFit()
idLabel.layer.anchorPoint = CGPointMake( 0, 0 )
idLabel.layer.position.x = 15
idLabel.layer.position.y = 10
idLabel.textAlignment = NSTextAlignment.Center
cell?.addSubview( idLabel )
}
// Update any labels text string
if let view = cell?.viewWithTag(labelTag) as? UILabel {
view.text = String( id )
}
// Return the cell
return cell!
}
i have a TableView with a customCell. I set the values of the customCell Elements inside cellForRowAtIndexPath:. No problem. But i want to change some customCell Element Values outside of the cellForRowAtIndexPath: Scope. For example after a Swipe i want to change the Value of a cell element inside my swipe function
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
let cell:customCell = self.tableView?.dequeueReusableCellWithIdentifier("customCell")! as customCell
let rowData: NSDictionary = self.tableData[indexPath.row] as NSDictionary
let imageSwipeLeft = UISwipeGestureRecognizer(target: self, action: "imageSwiped:")
imageSwipeLeft.direction = .Left
let urlString: NSString = rowData["testImage"] as NSString
self.indexPathArray += [indexPath]
cell.testLabel.text = "Test Label"
cell.testImage.image = image
cell.testImage.tag = indexPath.row
cell.testImage.addGestureRecognizer(imageSwipeLeft)
cell.testImage.userInteractionEnabled = true
ImageLoader.sharedLoader.imageForUrl(urlString, completionHandler:{(image: UIImage?, url: String) in
cell.testImage.image = image
cell.testImage.layer.borderWidth = 6;
cell.testImage.layer.borderColor = UIColor.whiteColor().CGColor
cell.testImage.clipsToBounds = true
cell.placeholderLoading.stopAnimating()
})
return cell
}
func imageSwiped(recognizer: UISwipeGestureRecognizer) {
let testData: NSDictionary = self.tableData[recognizer.view.tag] as NSDictionary
let imageSlide = recognizer.view as UIImageView
var imageURL = testData["image"] as String
ImageLoader.sharedLoader.imageForUrl(imageURL, completionHandler:{(image: UIImage?, url: String) in
UIView.transitionWithView(imageSlide,
duration:0.44,
options: .TransitionCrossDissolve,
animations: { imageSlide.image = image },
completion: nil)
})
let indexPath = self.indexPathArray[recognizer.view.tag] as NSIndexPath
let cell = self.tableView?.cellForRowAtIndexPath(indexPath)as customCell
cell.testLabel.text = "Test"
}
UITableView follows the Model-View-Controller pattern. According to this pattern, all your changes need to be done to the model - in other words, to the data structure that stores the information from which you populate your cell data. Once you made the change to the model, you tell the view that the data has changed, which would then show the new data.
Let's say that your cellForRowAtIndexPath function reads from an array. Your imageSwiped function should then locate the item that has been swiped, modify its entry in the array, and call either reloadData or reloadRowsAtIndexPaths.
That's it! Once you notify the table view of the reload, it would go back to the array, find the modified data, and call your cellForRowAtIndexPath to display it.
Specifically, in your code add an array called swipedCells to the same class where you declared tableData array:
var swipedCells = Boolean[](count:self.tableData.count, repeatedValue: false)
Now replace
cell.testLabel.text = "Test Label"
line with
if self.swipedCells[indexPath.row] {
cell.testLabel.text = "Swiped!"
} else {
cell.testLabel.text = "Test Label"
}
Finally, change the imageSwiped as follows:
let indexPathRow = self.indexPathArray[recognizer.view.tag] as Int
self.swipedCells[indexPathRow] = true
self.tableView?.reloadData()
This way the cells that you have swiped would continue to have a label "Swiped!" even after you scroll.
Ok after a huge amount of hours :D i solved my problem.
let indexPath = self.priceObjects[recognizer.view.tag] as NSIndexPath
let cell = self.tableView?.cellForRowAtIndexPath(indexPath)as customCell
i call this inside my imageSwipe function. Inside the cellForRowAtIndexPath function where i set the initial cell element values i store the indexPath inside an array. An i tag the Images to get a Index if the Swipe Events happens. I think it is far away from the ideal way...but works for me. I hope someday someone post the good way ;) cause this is very quick n' dirty.
