I have 15 sections with dynamic height sections and rows. By default all sections are closed. After scrolling to end of tableview, I am tapping on last section and it opens properly but when I click again to close section at that time my tableview scroll to top.
This issue occurs when some of the sections are scrolled and after that when click on any visible section.
Please anyone knows what exactly the issue.

I am creating an expandable UITableView. It works fine but the issue I am running into is when a given row is expanded and the user scrolls up, the opened section row scrolls up to the top of the visible table and stick.
In the below image, the detail row material and the succeeding section rows scroll OVER the opened section row.
I would expect that the section row would scroll off the top of the visible table view.
Am I missing something that would allow the section row to scroll up rather than stick?
I am working on a UITableView which has 2 sections, both of which have exactly 1 row which is a custom cell. This custom cell has a collection view which is used to display various products.
Specific to my issue, the two collection views have 6 cells(three rows in the collection view). However when I load the page, the second section only displays 4 cells (two rows in the collection view). I am using UITableViewAutomaticDimension for the tableview which has the cells that contain these collection views.
I have tried using setLayoutNeeded and layoutIfNeeded, I am calling reload data on the tableView in a number of places. I am reloading the second section specifically as well. However the only way the cell's dimensions get fixed is if I scroll down to the second section, then scroll up to the first and then go back to the second.
I have been stuck on this for the past 3 days and absolutely any help would be greatly appreciated.

According to this, I think you should reload your collection views firstly. And then reload your table view.
I know the title is confusing. So I explain what I expect.
I have 3 sections in my table view. The first section has one or more rows. And second and third sections has only one row. When the first section has more than 4 rows the next sections going to be visible by scrolling table view bottom.
But I need these sections be visible in this case.
Actually I need show these sections at the bottom of the visible frame when first section has more than 4 rows!
Is it possible ?
The thing you can do it to display only the 3 first rows of the first section and then when the user starts scrolling, you add the additional cells to the first section while he is scrolling until you've added all of your cell.
Do the opposite when scrolling to top.
You can use two different TableView instead of one.
declare first TableView with only one section & seconds TableView with two section with one row each.
for that you need to use UIViewController instead of UITableViewController.
in this way your bottom TableView Cell always stay visible while first TableView can scroll with more cells.
I am using a UITableview with dynamic height rows, and in content I have "Read more" type button. On tapping the button, I append data in a row and call reloadSections:withRowAnimation: for that section.
Everything works as expected, with just one problem - that the tableview automatically scrolls to some other cell after reloadSections:withRowAnimation:. Can anyone help me to find out why it is happening ?
I have a UITableView where I have section headers that can be tapped to expand or collapse the section. In my particular example each section only has one row, which is either visible (section expanded) or hidden (section collapsed). (I have a UITapGestureRecognizer on the section headers which I use to expand or collapse the sections) here the process of my actions:
I'm tap on the section (this is UITableViewHeaderFooterView custom view) and i see the cell that appears under the section header. At this moment everything is going OK. But when i scrolling down my tableview, cell goes behind header (like in Contacts application , header is first letter of contact). And finally when i scroll enough to don't see that section with that cell on, and when i scroll up - to return to my display that section - i want to make this section automatically known that when i return(from scrolling away that section from view) to it - i want that section already was closed with 0 cells in it.
Maybe i must use -(void) prepareForReuse at my custom UITableViewHeaderFooterView, or scroll methods ? or any tableView methods?
Thank you
You can implement the scroll view delegate methods and use them to check the scroll position (contentOffset) and / or the visible cells (indexPathsForVisibleRows). Once you know that you can collapse any sections that are no longer visible. You should probably use one of the scroll methods that means the scrolling has stopped (maybe scrollViewDidEndScrollingAnimation:) because changing the table view content size (which changing the number of rows will do) during a scroll animation could cause it to stop abruptly.
