TableView Cell Not Showing Content and Not Responding To Commands - ios

When working in the storyboard I can add labels and imageviews to a tableview cell but when I run the app they will not show. The only way I can get them to show is if they are in a stackview on a view within the cell. The cell will only not change colors on run time even if the cell's background color is changed in the storyboard. Is there any way I can fix this?

You should give us more insight to your project - that means your code, possibly your storyboard...
It's hard to tell what you did wrong when we even don't know what you did.
Did you connect your objects with outlets?
If you defined your own cells, did you selected them in storyboard?
How about your TableView Delegates?

How can I add a tableViewCell inside another TableViewCell?

the problem here is that I've got a component thats a cell, and I want to include it in a tableview with some other icons and labels in the cell. Maybe the best solution here would be to include a tableview inside of the cells, with a unique cell in it. I've tried to do it and it worked but when it came to launch another screen when selecting the cell it only worked on the margin where the inside tableview isn't included, how could this be solved? something like this Thanks!
Change the isUserInteractionEnabled property of the inner table view to false.

How do I implement the below view in iOS (Objective-C or Swift)?

Basically I'm trying to implement the feature which is attached as an image. I'm trying to create generic component. Where view can have list of items and minimum that could be shown will be two and there should be a button with 3 more options and click on should expand the view and auto adjust with the container using auto layout. Can any one help me giving brief idea how do I implement this? would be really help full.
Image and Component that I'm trying to implement is as below:
You will use UITableView with 2 UICustomCell one for default view like your image and another for expand view, use NSMutableArray to save flag value that decide to use the first cell or second cell, and in UIButton action reset this array and reload your UITableView.
I hope I help you.
1) If I right understand, the flexible solution it's creating UITableViewCell and UICollectionView as one of subviews (another - UIImageView). UICollectionView has two kinds of cells:
Cell with label - item.
Show more button.
Each time when you press Show more button just can reload UICollectionView without restrictions or insert new items.
But in this case you should manually calculate tableview's height. Implement sizeThatFits in UITableViewCell.
2) Also can add UIStackView and use it for your goal but UIStackView has bad performance.
Hope it helps you!

TableView and CollectionView in the same ViewController with Swift

I'm building my application with Swift and I want to set up TableView and CollectionView in the same ViewController.
The only answer I founded is to setup my CollectionView in the TableViewCell of the TableView.
I did it but it scrolls separately.
The solution I found is to disable CollectionView scrolling and then configure CollectionView's height constraint programmatically by summing heights of the cells. It isn't perfect at all because cells become non reusable (250+).
I'm in desperation because I have seen this setup in many other apps and I think that answer is so simple but I can not find it anywhere.
Can anyone please help me? Thank you a lot!
Another option is to set it up as a single collection view with two sections, one that looks and lays out as a tableview and the other that has the more collection view appearance.
Or set it up as a single table view with two sections, one of which displays two side-by-side images per line (this is the old school way of creating this layout.)
Lots of ways to go about it, depending on what you want to play with and what you want to learn :)
You can put a UITableView and UICollectionView inside a UIViewController, and implement UITableViewDelegate, UITableViewDataSource and UICollectionViewDataSource.
Keys:
Use AutoLayout to make sure tableView has only two rows, and
collectionView takes the rest of area.
Make sure tableView.scrollEnabled = false
Here is a sample, https://www.dropbox.com/s/v6yc40udfk8mqx5/FlexTableCellHeight.zip?dl=0
Set up a blank ViewController. Then place two ContainmentViewControllers inside of the ViewController. Size them however you want based on how much screen you want to the be tableview and how much you want to be collectionview. Then create segues from each containmentViewController to your tableviewcontroller and collectionviewcontroller using embed. This will allow both to be on screen at once and scroll separately.
If you do not need to use a TableViewController and can get away with just a tableview you can also just place one containmentviewcontroller below your tableview and create the embed segue to your collectionviewcontroller.

UITableview with Autolayout and NSFetchedResults controller cell layout bug on insert

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

Can I put 2 UITextFields in the same tableViewCell?

Check out this image below, this is what I'm trying to accomplish, but I ran into some problems. The first approach I made was to have an imageView (blue square) and 2 separate tableViews within a scrollView. Each tableViewCell would have textFields inside them. The first issue was when the keyboard came into the view, I would move the view up to make sure the bottom textFields were not covered up. I then wanted to be able to scroll up and down so I could still see the top textFields as well. This didn't work because when I nested the tableView inside the scrollView, The scrollView wouldn't scroll. I was also having a problem with setting the firstResponder to pass from textField to textField on the second table only.
I then decided it would be better to create 1 tableView, and add a custom cell to hold my imageView and two textFields. My question is, is it possible to create that custom cell that will hold my imageView and two textFields? would this be a better approach?
Thanks
Wow, I think your can do it easily by UITableView. All you need to do is customising UITableViewCell.
This is possible using subviews. However, why you aren't considering UIViewController or UIScrollViewController for this design?
