I'm trying to find a way of making the height of a UITableView change depending on how many rows are in the table being displayed.
I've gone through the site for previous questions but none really come to any conclusion.
Language being used is Swift on iOS 8.
Thanks,
Anthony
Use tableFooterView to pin content to the bottom of a UITableView
EDIT:
The tableFooterView (and tableHederView) can be modified directly in Interface Builder by dragging a view below (or above) the prototype cell(s) in your table view.
I wanted to do this within the IB. The way around it was to drag a new view underneath the prototype cell that was already showing in the IB. Then I could change the size to suit my footer content and then just add the footer parts of the layout to that new view within the Table View.

I have a UICollectionView with custom UICollectionViewCells. I used Interface Builder (via XCode 8) to size the collection view and cells when first making it.
Now, I'm trying to adjust the size of the cells and I'm unable to do so in Interface Builder (using XCode 9). I cannot adjust the width or height of the cells on either the collection view itself or on the custom cell. The up/down arrows don't do anything and neither does typing in a value. It just stays set at 145.
I saw some answers about not being able to do this with a UICollectionViewController via Interface Builder, only a UICollectionView, but it is a collection view and not UICollectionViewController.
I'm sure there's some new setting/config in XCode 9 that I'm missing, but I can't figure out why I can't adjust the custom value.
I ran into the same problem.
Turned out that the item size was defined by the contained flow layout. So editing the item size in the flow layout, and the parent collection view had its item size changed accordingly.
I tried Jonny's answer, but I use a custom FlowLayout and couldn't edit it's cell size either. I had to manually edit the size of the collection view, the cell and the layout in the storyboard source code (right-click on the storyboard in project view and select "open as / source code").
Now the size is correct but still not editable from the UI ¯_(ツ)_/¯
Same problem, width would not change. But I changed the height to something different and it then let me edit the width.
Xcode 12.3. I had the same issue and what fixed it for me was changing the collection view scroll direction from vertical to horizontal to make the change, then obviously reverting back to vertical (my intended direction) once I was done editing the values.
I would like to construct a view controller where one section of the view controller would be still and one section scrollable.
Both sections have headers where as well, one is still and one is moving along with the content in the section.
I do not want the cells in the section to be scrolled separately. All cells should move at the same time along with the header.
I have added an image to make my point little more clearer.
Use UICollection View for both view and disable scrolling for one view and enable scrolling for another view
you can probably add to your UIViewController view a UITableView on the left with fixed size (for example 150px) and vertical scroll disabled and a UICollectionView with horizontal flow and ,if needed a, with custom UICollectionViewLayout (but i think that you just need the classic UICollectionViewFlowLayout) for the right part that fits the remaining space.
Here you can find the component's documentation:

I seem to be having a very strange problem with my UITableview cells and autolayout. So my tableview is set up as follows:
I have a UITableView within a UIViewController that I created via Interface builder using Autolayout
My tableview is using UITableViewAutomaticDimension so that the cells can resize based on the text within them.
Each cell has 2 subviews within it. A front view and a back view. The back view contains the buttons for my slide-able cells
I am using NSFetchedResults controller to update the tableview
The problem occurs when I tap on a cell and am taken to the next view. Then I create a core data item within that view and save so that it is inserted into my tableview (now behind the current view controller).
What happens is that the newly inserted cell seems to lose all autolayout constraints and all view elements are on top of each other in the top left of the cell. It also looks like they are not even contained within the front view for the cell (or the front view has a width and height of 0).
Example:
It gets even stranger. If I refresh the tableview by pulling down and the cells are reloaded it corrects itself. However, if I refresh the tableview again then the problem appears again but on a different cell. This bug does not happen consistantly which is rather frustrating.
Any help would be appreciated as I only have a few remaining hairs on my head to pull out at this stage.
Thanks in advance!
So I found out what the issue was. The issue was that I was using size classes in Interface builder but I was only using the iPhone Portrait size class and did all my work in there instead of the "any" size class. Disabling size classes and setting the project to iPhone only fixed all these problems.
Weird I know
I am building a simple iOS application using Swift.
One of my views, displays a list of comments (cells in a PFQueryTableViewController...I am using Parse.com for my database).
My cells resize happily in order to fit the possible multiple-lines of the comments. This is MAGIC! (if you ask me)
What I am having trouble doing, is making the UIView which is at the top of the TableView resize based on multiple lines worth of content for the Label in that top view (see below).
Instead of doing multiline and resizing the view (I have set up constraints and set lines of text to 0), the label only shows one line, truncating it at the edge of the screen with "..."
Does anyone have any suggestions or solution for how to cause my top UIView to resize based on the content of the UILabel?
I was also thinking this could maybe better be done using a Container View at the top of the TableViewController?
There is a delegate method in UITableViewDelegate that lets you return the height of the head view (heightForHeaderInSection). You have to implement it making sure you return the proper height.
If you have a nib with constraints already, you can load the nib in a #property, and use the method systemLayoutSizeFittingSize that should give you enough height.
For more details checkout this post I wrote a while ago: Customize the UITableview with different height of cells like Facebook feeds in iOS
Is there a way for a table view header section to have a bigger width then the actual table? Here's a simple picture that shows what I mean:
Basically, I need to make the header section to extend beyond the small table view.
Is it even possible?
Thanks!
What worked for me is subclassing UITableCell and overriding setFrame method.
