Product:iOS SDK Product Version:10
Classification: Reproducible:Always
 
Summary:
Using a UIRefreshControl with custom tintColor (blue) in a UITableViewController inside a UINavigationController.

If -[UIRefreshControl beginRefreshing] is called on viewDidLoad or viewWillAppear, the table's content offset is changed to show the refresh control but the view is blank, the refresh control does not show.

If called from viewDidAppear, the table's content offset is unchanged. A slight scroll up reveals the refresh control, but it has the default black tintColor. After manually refreshing it the tintColor is correct.

Steps to Reproduce:
Run the attached sample project and tap on the appropriated buttons.

On the viewDidAppear option, scroll up very slightly.

Expected Results:
If called from viewDidAppear and programmatically changing the table's content offset, the refresh control appears and has the desired tintColor.

This should be the behavior wether beginRefreshing is called from viewDidLoad, viewWillAppear or viewDidAppear.

Actual Results:
refreshControl appears blank or doesn't appear at all

Version:
iOS 10.0 (14A5309d)

Notes:
The bug also occurs when building with the iOS 9 SDK.

Configuration:
iPhone 6s 64gb

Still broken in the iOS10 GM

Unfortunately there has been no change in the GM, and I'm yet to find any workarounds!

For some reason, not just UIRefresControls, but also some UIActivityIndicatorViews are affected in my codebase.
