Hello all,
Since I updated to 5.5, I cannot launch my application by opening an
email attachment or such methods, for file extensions that have been
registered for my app in info.plist
I can open the documents only if the app is already running.
I can see in the app's log the following message:

The full story is that I override QIOSApplicationDelegate to be able to
manage didFinishLaunchingWithOptions and openUrl methods, but even if I
remove my implementations and let Qt regular QIOSApplicationDelegate
load, I get the same crash. I can see that main.cpp reaches the point
where it calls qApp->exec() and stays stuck there until a timeout of
some sort occurs. I can see that didFinishLaunchingWithOptions is called
if I activate my own delegate, as you can read from the log. But anyway
with or without my own delegate, I get this crash when I launch the app
through a file opening. What is this message about CoreAnimation taking
too long that I don't get when I launch the app normally?
If I launch the application by clicking on the icon, it works and takes
less than 2secs to load, and it will even accept all incoming files
through openUrl. didFinishLaunchingWithOptions is called at startup too,
but with no url as expected.
I am sure that was working before with qt 5.4.2.
What should I do to make this working? And btw what is the recommended
way to override QIOSApplicationDelegate in order not to be annoyed each
time a new qt version is released, and still be able to handle openUrl
and such?
Thanks in advance
Philippe Lelong
