iOS 9 constraint issue while playing video in full screen #174

Open AlphaBetaDebug opened 8 years ago

AlphaBetaDebug commented 8 years ago

I am seeing "Unable to simultaneously satisfy constraints" error in Xcode console when running app on iOS9 device/simulator when videos are playing in full screen. I didn't see this issue on iOS8.

Update: It seems like a iOS 9 bug from apple where fullscreen videos played from UIWebView shows these warnings in console.

I have the same issue, but warnings are a lot longer. Is it good to leave as it is?

Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it. 
    (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Issue while i try to exit from full screen mode on landscape when my app supports only portrait mode. Appears while using YTPlayerView and iframe embeded in HTML on WKWebView.

See the same issue when exiting from full screen mode on landscape while the previous view controller is portrait only

I see this with iOS 10
