Closed iomark closed 12 years ago

iomark commented 12 years ago

Environment: Xcode 4.2, iOS SDK 5.0, iPad 5.0 Simulator, CoconutKit 1.1.1

Steps for reproducing: 1) start CoconutKit-dev in iPad Simulator; 2) select HLSPlaceholderViewController; 3) tap "Hide with modal" 4) tap "Close" in appeared modal controller.

Actual result: two pairs viewWillAppear/viewDidAppear. Expected result: one viewWillAppear and one viewDidAppear.

This is a known iOS 5 issue (documented in the HLSStackController header and in the README file). I already filed a bug report for it: http://openradar.appspot.com/10822029. Thanks for the feedback anyway.

Fixed in commit 5bd12e8ad0ec9e79c710909ca9b7bf858c4b46b4

This was not an iOS 5 bug, but a hidden behavior of addChildViewController:. I should file a radar for lack of documentation, I think :-)
