iOS - Load only visible cells

[cosminstirbu]

Hi,

I am using Appium 1.6.0 and XCUITest automation name and I am trying to check if the first visible cells have a given property.
The issue is that my table view is paginated - this means that when

open func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath)

is called for the last cell in my data set I make an API call to load more data, even though the table isn't scrolled at all.

I use the following approach to retrieve the elements:

@iOSFindBy(accessibility = "MyCellAccessibilityId")
List<MobileElement> cells

The problem is that Appium or WebDriverAgent triggers open func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) and there fore the data pagination and the list retrieval of cells takes forever.

Is there a way to prevent Appium to trigger open func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) and query just for the visible cells?

On Android the exact same approach doesn't trigger the data load.

Thank you,
Cosmin

i made such workaround in controller TableView for Simulator:

    #if DEBUG
    // workaround for automated simulator build to ask ALL
    if InSimulator {
        let cellInTableView = tableView.rectForRowAtIndexPath(indexPath)
        let cellInSuperview = tableView.convertRect(cellInTableView, toView: tableView.superview)
        guard cellInSuperview.center.y < UIScreen.mainScreen().bounds.height else {
            return
        }
    }
    #endif

My solution turned out to be to move the pagination trigger in the func scrollViewDidScroll(_ scrollView: UIScrollView) delegate method.

I do that in the actual production code so I haven't added any Debug / Simulator checks.
