RefreshControl issue on tableView

[perage]

Hi,

I have a viewController with a tableView (not UITableViewController) and a FUINavigationBar. When adding refreshControll, the animations doesn't work like they should, e.g the NavigationBar doesn't always move back up, and the loading indicator is just blinking for a split second. When changing the NavigationBar back to UINavigationBar, it works like it should.

Any suggestions on how to fix this for FUINavigationBar? Also, any idea why the whitespace on the top is there - it came with xcode 12 I believe..

@IBOutlet weak var table: UITableView!
let refreshControl = UIRefreshControl()
refreshControl.addTarget(self, action: #selector(refresh), for: .valueChanged)
refreshControl.tintColor = .white //this is needed as it is grey/black by default
table.refreshControl = refreshControl

On a side note it seems to me that there is some custom code here, trying to mimic Apple's animation from large title to small title for example. When scrolling down on a NB with large title on UINavigationBar it transitions to small very smooth, but with FUINavigationBar, it kind of jumps from large to small.

Hi Per Age,

Could you provide an xcode project to reproduce this problem so that we can take a look and try to fix the problem.

Thanks.

jan-hua.chu Please clone this repo

It seems likeit happens for one or two reasons:

1. See first tab - searchController is present, making the refresh being part of the navBar somehow. If you remove the searchController, it seems to work.

2. Second tab - largeTitleDisplayMode = always for first view, making it not work. In second view (navigate to "all", largeTitleDisplayMode = .never making it work, the same way as for pt. 1 if searchController is removed.

Thanks for looking into this 🙂

jan-hua.chu Have you had a chance to look into this?

Not yet. I am on vacation this week. Will look at this next week.

Please let me know the SAPFiori framework version to be used for your test project.

Thanks.

In your case, please change the search bar to tableview header. i.e., change the following line

`navigationItem.searchController = searchController`

to

`tableView.tableHeaderView = searchController.searchBar`

Also, since this change will move the loading indicator to the table view header instead of the nevigation bar, the `refreshControl1.tintColor` you should change the color to a more noticable color than white, or just use the default color.

BTW, it is recommended to use `FUINavicationController` instead of `UINavigationController` to make the status bar text the correct color for iOS 13.4 and later. Note that simulators may display different color than the desired color, you need to use the real device to see the correct behavior.
