I want to implement a list containing several images grouped together like in the following mockup. The number of images to display in each section is dynamic and may vary. I also all images in a section to be always visible (without having to scroll horizontally or vertically).
What is the best approach to achieve this? I was making some tests with UICollectionView inside UITableViewCell but I can't make UICollectionView/UITableViewCell size expand automatically depending on the number of images inside.
Is UICollectionView/UITableViewCell the way to go or is there a simpler approach?
You don't need the UITableView to achieve this, here is the link for the implementation of Sticky Header for the UICollectionView.

You need to implement collectionView delegate and dataSource methods inside uitableViewCell. Look it:https://contentpedlar.wordpress.com/2016/10/22/uicollectionview-in-uitableview/
This in Swift, but you easy understand it in Objective-c

I want to customize my tableview. I want to add another tableview in cell. Can we add tableview in cell of another tableview?
Please give me some ideas.
You can embed a UITableView into another UITableView's cell, but due to potential issues with the embedded UIScrollViews it is not recommended.
If you feel like you need a table in a table, first consider if it is not possible to achieve the desired behavior by using sections and cells in the sections (a section in a table might represent the top tableView's cell, and cells in the given section would represent the embedded tableView's cells).
There is no problem with adding a UITableView into a a UITableViewCell, since both of them are UIViews its simply would be translated to adding a subview to a view...
However, keep in mind to consider the following issues:
1- From a user experience perspective, that would be a vertical scroll view inside another vertical scroll view (are you ok with that?).
2- For each cell -in the main container table view-, you would need to handle the table view delegates/datasources. For understanding the logic of how this could be done, you might want to check:
Is it possible to add UITableView within a UITableViewCell.
Putting a UICollectionView in a UITableViewCell in Swift: although it is about adding a UICollectionView inside the cell, it helps to gain the logic of how to achieve such a task.
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!
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.
As seen in the image of my design that i have attached, i want to merge(don't know wether thats the correct word) the first three cells so that i can display an image at the right side in the table itself. Is it possible?
No it's not possible. Instead, you can create first three as one cell(type1), other cells are other type(type2).
Update: see this tutorial for how to create custom cell.
You can create a UIView with fixed dimensions(say, 200x200) having 3 textfields (number, name & uom) to left and add UIImageView to right. Create IBOutlet of this view and name it. Add this view to the header of your UITableview.
self._table.tableHeaderView = yourview;
You should use a UICollectionView instead and apply a custom layout to achieve this.
Collection views provide the same general function as table views
except that a collection view is able to support more than just
single-column layouts. Collection views support customizable layouts
that can be used to implement multi-column grids, tiled layouts,
circular layouts, and many more. You can even change the layout of a
collection view dynamically if you want.
There are many tutorials on the Internet:

Another option is to use UITableView and a custom UITableViewCell.
Example:
http://www.idev101.com/code/User_Interface/UITableView/customizing.html
add it in the first cell.The size of you imageview shoud be greater than the cell height.Make sure cell.cliptobounds is set false.Make sure you set the zpositon of imageview to 1 by imageView.layer.zPosiziton = 1.
Actually, you can add your imageView as subview of tableView, so your didSelectRowAtIndexPath: will working as usual
I'm designing a layout for my app that is going to take advantage of UICollectionView. I have created some moderately complex collectionView-based apps before, but I may need to subclass the layout class for this one. The main point I'm trying to figure out is whether I can have different sections of the same collectionView scroll in different directions.
Based on what I have read and tried so far, the only way to have one section scroll horizontally and another vertically would be by using multiple nested instances of UICollectionView.
This is a basic idea of my layout. My guess is that even with subclassing, a single UICollectionView would not be able to handle it. Or would it?
I think you could do it with a custom UICollectionViewLayout but I'd use the default flow layout with one cell containing something like a SwipeView for the section 0 and other cells in your section 1.
