The problem is that I'm getting too much of it in relation to line length and text-wrapping.
Here is the code I added to the view controller's viewDidLoad():
tableView.estimatedRowHeight = 80
tableView.rowHeight = UITableViewAutomaticDimension
Here's the code I added to the Message Cell's configureCell() function to try to solve the problem:
self.sizeToFit()
self.layoutIfNeeded()
And finally, here's a screen-shot of the constraints I've applied.
Message Label constraints
Despite all of these attempts to solve the problem, my cells keep ballooning geometrically as I add more text. Any suggestions on a fix?
Edit: Here's what the problem looks like:

I'm having this weird issue with UITableView that can't calculate it's content's height properly.
I have custom UITableView class that is embedded in another custom UITableView, I want it to auto-adjust it's height to fit content so I have already:
override var contentSize: CGSize {
didSet {
self.invalidateIntrinsicContentSize()
}
}
override var intrinsicContentSize: CGSize {
self.layoutIfNeeded()
return self.contentSize
}
And now when I use:
self.estimatedRowHeight = UITableView.automaticDimension // non-zero value like 40 isn't working either
self.rowHeight = UITableView.automaticDimension
the output is the frame that is not full height, when I turn "Scrolling enabled" in this TableView it's scrollable with full content (don't want that):
Now when I change
self.estimatedRowHeight = UITableView.automaticDimension
to:
self.estimatedRowHeight = 0
the output is exactly what I would want to have except the content text is cut...
Here's my CommentCell:
Console isn't showing any errors with autolayout in any case.
Do you maybe know what's going on? I have spent literally days trying to get those comments to work and that's the last thing I need.
If you need any more info please just tell me.
Edit:
If i change estimatedRowHeight to a large number for example 500 I get loads of empty space under cells:
So it looks like TableView can't fix the cell height to content. Maybe this will help someone.
Maybe it's about the textfield inside the CellView. Did you set it's Layout to wraps?
Also I would try to set it's intrinsic size value to 'placeholder' inside the Size Inspector.
I'm trying to place a table view inside of a basic view controller without any padding on the top and nothing I've tried has worked, no matter what I do there is a gap up top. I placed the following code in my viewDidLoad() for the view controller:
if #available(iOS 11, *) {
tableView.contentInsetAdjustmentBehavior = .never
} else {
self.automaticallyAdjustsScrollViewInsets = false
}
I've gone into storyboard and disabled those settings as well manually:
I do have custom cells I'm not sure if that matters, I do add insetting to the cells but even when I remove that code I have that gap.
Here's the code I customized for my cells:
override func layoutSubviews() {
super.layoutSubviews()
contentView.frame = UIEdgeInsetsInsetRect(contentView.frame, UIEdgeInsetsMake(cellSpacingHeight, 0, 0, 0))
}
I've spent a couple hours googling around and I can't figure it out. I'm using the latest swift and Xcode to build this. I even tried to print the values for the tableView's content inset and it came up as all 0s. Does anyone know why I still have the offset or inset up top in my table view?
Wow okay so I finally figured it out, I had set the table view style to Grouped at some point instead of Plain. Once I made it plain, everything worked, I hope this might help someone else in this position!
I am making an IOS app where the main layout is a UITableView, and cells are completely dynamic and loaded from server. Each tableview item is a different layout.
For example, lets take first item of the tableview:
Server tells it should have a label, 2 buttons and a textbox, it should be created by code. I figured out how to create those elements themselves, the problem is how do I position them?
Ideally I would like to add each layout item under the previous one. And tableviewcell should wrap those, grow or collapse according to views.
I am fairly new to IOS/Swift. Is there any way to implment this easily? In android I just used a linearlayout and added views one by one. Does IOS have something like that? Or do I have to manually set heights, widths, and coordinates of all items?
Thanks in advance.
Here is some code:
if let Actions = AppData["Forms"][0]["AvailableActions"].array{
for var i = 0 ; i < Actions.count ; ++i {
if Actions[i].int == 1{
let actionButton1 = UIButton(frame: CGRectMake(0, 0, 96, 30))
actionButton1.setTitle("View", forState: .Normal)
actionButton1.setTitleColor(UIColor.redColor(), forState: .Normal)
cell.actionsLayout.addSubview(actionButton1)
}
}
}
You can do with self-sizing cells, in this case you just need to
Give proper constraints to your table view cell subviews,(i.e all
your subviews should be connected to each other and topmost
subview should have top-space constraints and bottommost subview should have bottom-space constraints).
Specify the estimatedRowHeight of your table view.
Set the rowHeight of your table view to UITableViewAutomaticDimension
For step 2-3 steps mentioned above,just add following code in your viewDidLoad -
tableView.estimatedRowHeight = 44.0
tableView.rowHeight = UITableViewAutomaticDimension
For understanding of self-sizing cells you can follow this link

I have a tableView with the bottom of low hanging characters (g, p, q, etc) in detailTextView being cut off. Changing the font size and cell height doesn't seem to fix the problem. I can't set values of the cells labels so I am out of ideas. Any help?
Here is a pic of an example.
EDIT: I found that using fontawesome is what is causing this. I have no idea why fontawesome is doing this but removing this line of code in my cellForRowAtIndexPath removes the problem
cell.detailTextLabel!.font = UIFont(name: "FontAwesome", size: 16)
Now I have no idea why changing the font is causing this issue, nor how to fix it.
You have to add these two lines of code to your UITableView set up:
tableView.rowHeight = UITableViewAutomaticDimension // 1
tableView.estimatedRowHeight = 50 // 2
// 1 This tells the UITableView that its cells should be as height as their content
// 2 This is needed by the UITableView to calculate its scroll bar height and position. This value does not have to be 100% correct, an estimation on your average cell height is enough.
I am trying to make a table view with a dynamic cell containing an image view and 3 labels in Interface Builder, but for some reason the table view row height isn't being set properly and all the content is being cut off. This is the only code for it:
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 100.0
}
And my interface builder constraints are almost similar to the ones shown below from a Ray Wenderlich tutorial (http://www.raywenderlich.com/87975/dynamic-table-view-cell-height-ios-8-swift)
Here is a sample of the simulator output:
If anyone has any insight on how I can fix this, I'd be more than happy to hear you out. As you probably guessed, I am trying to make it so that the cell height expands according to the subtitle length (a la Twitter) but to no avail :( Thanks!
Update: It looks a bit better now but still not expanding as the UILabel expands :(
In the UIViewController which has your UITableView as a child view(or it can be UITableViewController) make your table view cell height "100" too.I think it is 44 now?
Also if it not set already, set your subtile's "Lines" property to "0" in Interface Builder to make it self-sizing.
You are using the estimatedrow height. There is an another delegate method for height that you have to use. It is just rowheight delegate. Use heightForRowAtItem index version of objective c in swift.
Solved it! My constraints were correct but for some odd reason the tableView wasn't updating. Adding the following code seemed to make it fine:
override func viewDidAppear(animated: Bool) {
tableView.reloadData()
}
If you have any better suggestions feel free!
