Dynamic number of uibuttons in uitableviewcell with sections swift4 - uitableview

dynamic number of uibuttons in uitableviewcell with sections
Hey guys I want to implement a UI like the one in the link above. The tableview has cells with sections and each section has a different number of uibuttons from the other. The number of sections and the text on the buttons are got from server data. Each section can either have one or two or three buttons at each cell depending on the number of data return and the length of the text. I'm implementing this without the use of storyboard or interface builder using Swift4.2 and Xcode10.

Please use collectionView in tableViewCell.
Set the collection view cell count according to the button count.
It may helps you. Thank you.

Collectionview inside tableview cell with dynamic height cells and dynamic content swift 4

I am working with collectionview inside tableviewcell in Swift 4. I get the content from server which is all dynamic. I have to show different types of collectionview behaviours.
For example, in the first tableview row should be collectionviewcell with screenwidth and scrollable. In the second row, collectionview with 3 sections and each section has different content different number of items.
Here I got stuck I am unable to show 3 sections one below other it is showing besides horizontally. I have calculated collectionview flow layout size.
Also in last row I have collectonviewcell with scrollable content,here when i scoll the content is repeating from bottom row or top row. I want the smoth scrolling and to stop repeating the content.
I am new to Swift. Can anybody help me out of this . Thanks in advance.
The smooth way is to create tableview with its cell xib and inside its cell add collection view and create another xib for collection view cell. This method is helpful when accessing collection view for different tableview cell. Rather using without loading Xib's may mixup your code.
You have to set tableview cell height as UITableViewAutomaticDimension. This will handle your cell height as per your dynamic content.
For each tableview cell you have to set collection view's property by using cell's index path as per your requirement.

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.

Each cell with different layout in TableView, how is scroll optimised?

If I have a UITableView with each cell having a different layout. For example, cell 1 has one text field, cell two has two text fields and so on, in this case height of tableview cell varies based on how many text fields it has one below the other. For this specific scenario, will I be able to make use of reuseIndetifier and reuse the cell.
Is tableView reuseIdentifier useful only when layout of each cell is same? Or can I still reuse cells by making use of single identifier but adding textfields in cellForRowAtIndexPath dynamically?
I experimented a bit. I can do some basic reuse of cells by having a cell with empty template/blank cell. But in the cellForRowAtIndexPath I can dynamically create text fields and add. This works perfectly fine, allowing me to add as many number of views required to be added to TableView cell. I am using blank cell, which will be reused on scroll. However I am not sure that will be the impact on performance when I create and add UI elements dynamically to the cell in cellForRowAtIndexPath. Any ideas there?

iOS: Hide all lines for specific section in UITableView

I have UITableView with two sections, and I want the first section to appear without lines.
is it possible to hide all lines (top and bottom lines and cell separators) for only one section ?
No, separatorStyle is a property of UITableView, so there is no way to change it for specific sections / rows.
But it's not hard to implement yourself, with a custom UITableViewCell subclass

iOS how to name cell IDs?

I am confronted with the same issue as this post Iphone - cellForRowAtIndexPath behaving weirdly when scrolling down and up. I am confused how I should be using different cell IDs for different cells. I have a variety of cells:
cells with switches
cells with checkmarks
groups of cells such that only one is checkmarked
cells that change text after tapping them
cells with indicators
cells with no accessory type
Should I be using a different cell ID for each of these different types of cells?
I would use different reuse identifiers for each different type of cell. That would make it so you won't have to do things like take a checkmark cell and change it to a switch cell. You'll dequeue each type of cell and get back what you expect. Does that make sense?
