user preferences and maintaining state

[potem...@googlemail.com]

Hello,

first I want to say that I really enjoy the tutorials!
The point about Iphone development I am left most puzzled about is how
best to store user preferences and how to maintain the state of an app
when it is forced to quit by the OS.

Should I store everything in a "plist" file?

It would be great if someone could post some sample code.

Thank you very much.
Phil

Hello,

thank you for the tutorials - great job! I have a question regarding
the invoking of the preferences within an app, but I will ask it in
the comments sections.

Back to the second part of the question of this thread on how to
maintain state. Is it possible to dump an object to memory when the
app is quitting or should
I always store the current content and data of the app in a XML file
or something similar as the application might be killed rather
aprupt?

Thanks,
Phil

Hi Phil,

You can implement "applicationWillTerminate" method in your
application delegate implementation file. Which will be called if you
app is shutting down for any reason.

It depends, you store the state in the database, application
preferences, I think it would depend on the data.

I know Apple said that we could store the status of the app in their
cloud and get it again when the application is launched.

Thanks,
