AX ERROR when using Accessibility Inspector for iOS app.

Question

I'm testing an iPhone app with the simulator. Whenever I click on certain elements, I receive this error in console:

AX ERROR: Could not find my mock parent, most likely I am stale.

This error does not seem to cause any side-effects. I can use the app and examine the elements freely. Any idea what it may be caused by?

Change made to fix issue, you might need to pull changes and update your library.

Answer 2

For me the problem was that the code path eventually called

[tableView beginUpdates]
[tableView endUpdates]

within the tableView:cellForRowAtIndexPath: method.

Removing the call got rid of these AX Error log messages as well as a bunch of other UI glitches.

Cool!

I just have this strange error when using MJPopupBackgroundView. After checking its codes for a while, I noticed that, the author added a UITableView to another UIViewController's view as a sub view, but he didn't add the table's view controller to the other UIViewController as a child view controller.

So the solution is quite easy, after adding a sub view like this:

[parentViewController.view addSubview:childViewController.view];

You only need to add one more line like this:

[parentViewController addChildViewController:childViewController];

Voila!
