151886 2015-12-04 14:41:15 -0800 Background state not being tracked correctly for PDFs on iOS 2015-12-04 15:10:05 -0800 1 1 1 Unclassified WebKit WebKit2 Other Unspecified Unspecified RESOLVED FIXED P2 Normal --- 1 barraclough barraclough oldest_to_newest 1146410 0 barraclough 2015-12-04 14:41:15 -0800 The problem here is that when viewing a PDF we don't have an ApplicationStateTracker. (While we do have a content view - which normally holds the ApplicationStateTracker - the content view is not in a window, and only has an ApplicationStateTracker while in a window). For now, let's give the WKPDFView an ApplicationStateTracker of its very own. In the future we may want to refactor ownership of the ApplicationStateTracker up to the WKWebView. 1146415 1 266663 barraclough 2015-12-04 14:46:33 -0800 Created attachment 266663 Fix 1146416 2 266663 andersca 2015-12-04 14:53:14 -0800 Comment on attachment 266663 Fix View in context: https://bugs.webkit.org/attachment.cgi?id=266663&action=review > Source/WebKit2/UIProcess/API/Cocoa/WKWebView.mm:756 > + return ((WKPDFView *)_customContentView.get()).isBackground; For RetainPtr we don't use property syntax because it looks bad.

I'm already checking _isDisplayingPDF, which does exactly that (and other methods checking via _isDisplayingPDF then cast without an additional ASSERT). Guessing you missed the _isDisplayingPDF check, & thought I was just checking _customContentView - as such going to leave as is for now, but let me know you strongly disagree. Have made the other requested property syntax change. 1146424 4 barraclough 2015-12-04 15:10:05 -0800 Committed revision 193481. 266663 2015-12-04 14:46:33 -0800 2015-12-04 14:53:14 -0800 Fix
