In table view with many rows, is it possible to have the top row (row[0]) "frozen",
while the rest of the rows 'scroll' up an down.. If you have any hints about this, it would be appreciated..
The only way to do this would be to use a section header as the top row. Otherwise, do the top row as a separate UI element.

How to design and code this in swift(IOS) AND Xcode.If we tap on down button it should display items and vice-versa like this:
You need a Collapsable TableView. In order to achieve that, in your TableView you must keep track of which sections are collapsed (contracted) and which of them are expanded. For this you need to maintain a set of indices of sections that are expanded, or a boolean array where the value of each index indicates if the corresponding section is expanded or not. Check for the values at the specific index while assigning height to a certain row. Check this link for more help.
Refer ans by #Cristik.Refer my previous ans for more info.
You need expandable table view. Basically, you need to control the open and close of sections of your table view.
Here is an good example with working code & animation written in swift 3.0
I'm trying to build an accordion style ( expand/collapse ) list in IOS/Swift 3. Was confused on which approach to follow like a static UITableView ( since my sub divisions have different types of Ui Controls in the cells ie some have checkbox ,spinner, textview etc. with labels to show configure a list of different Valves) , UIView with nested UIViews sections with an option to clip views . But both have been messed up with without any success.

Any other approach without UITableView?
Please help . Thanks in advance .
Static vs dynamic table will depend on your data source. Does your data source for your table change? If so you'll want a dynamic table, if not then you can design it out in a static one.
As for the accordion feature, what I've done in the past is to add a tap gesture recognizer to the header view of each section. When the tap is detected I change my datasource and reload the table view. What happens is that number of rows for section is called on reload, and I return 0 so that none of the rows show. When tapped again you can go back to showing the normal number of rows.
To get the animation you need to use delete rows with index paths and animate it.
I have a requirement where UIPickerView should be customised. The picker view should look adjacently like this!
[https://docs.google.com/drawings/d/1CHCBvB1IEebj82Xt1ZGBYTKhCUMBmeAeQBV5fvbI-6s/edit?usp=sharing
Any ideas on how to achieve this feat?
Don't use a picker view, you will break your head attempting to get it right.
Use a pair of ui table views, the left table cells correspond to right table sections. The right table sections are hidden until their respective, parallel row is selected
Sorry about formatting, on iPhone
I have three different kind of objects that I want to display in collection view.
But if in section 0 is only 1 element, next section starts from new column.
Can I tell to the layout that it should show items in different sections one after the other with no breaks?
Sure, but if that never changes, why not make two side-by-side sub views?
The left one contains the one element, the right one contains the collection view you originally planned to use.
That way the layout doesn't need to know how to work around the left element.
Additionally, you can use one data source. Make datasource[0] the left one,
And use datasource[indexPath.row +1] for the whole cellForRow..... method.
Just remember to set total cells in the collection view to [datasource count] -1
My solution is to use 1 section and create methods for determinate abstract sections.
In addition, I add -infoItemsCount, -visibleItemsCount and -hiddenItemsCount and same methods for generating cells and other.
Is it possible to add columns to a table view in ipad?
If yes, please tell me how to do that.
You can put anything you like in a cell. But cells are essentially rows, so no, there's no built-in support for table columns.
