I am currently working on a grails project. What I am trying to do now is to create an application that can store values of the user input without saving it on a database, and later access that stored values for further processes. Is there a way on how to realize this?
Please help. Thanks!
Update:
Sorry for the vague question..through further reading I have come to a solution that putting the user data input in a file is the solution to this query. It would be saved in a non-volatile storage, but not in the database perse..Thank you so much!
The options are almost endless.
You could just keep the data in memory, if it doesn't need to survive a restart.
Otherwise, you could write it to file, etc.
But it all comes down to pretty much the same thing as using a database.
Just curious - why don't you want to use a database?

I need to add unlockables to my application, but the problem is that I don't want to have to send out an update every time that I want to add something new. I have read a bit about servers and JSON and XML. I just wanted to check to see if anybody else had a better idea?
If you are talking about something like a logo change then, short of an app update, the only option you have is getting it from an outside source such as a server transmission. But now you are talking about in-app purchases which, if you have not already, should read up on.

Server based image and/or text transmissions are easily done and if I understand your last comment correctly, these updates would not be very frequent anyway.

Is there a way to make an app compile data from a website? I need to make an app that will display a name, address and some short details - but I need this information to be regularly updated and contributed to by admins, without requiring me to continually add the new information into the app.
I have not done an app of this kind before so any help or assistance would be most appreciated!
Mainly two types of web service available
SOAP
REST.
Use the parsing technique (XML parsing,JSON parsing) depends on the type of web service to parse the data.
The information will be updated automatically in your application when ever some change in the web service happens.
I hope you will get some idea.

In a different question I was suggested to use SSKeychain, and after searching the web it seems that SSKeychain is the preferred method for working with Keychain.
It is very hard to find code examples, and the ones there is just stores a string, which is a password.
How would you go about saving and retrieving a NSArray with SSKeychain, when you have several keys you wanna store in the keychain.
Thanks.
Have a look here: http://github.com/granoff/Lockbox. It's a project I built to store data securely in the keychain, which has the added advantage of surviving an app being deleted and re-installed.
This is drop in class. It just works.
EDIT: Now it just works. I think something about Xcode 4.5 got more strict than when I originally developed Lockbox. Thanks to a contribution from a forked version, it is again simply a "drop and go" solution.

we have an app where the user get there own userspace an can create entries without login.
we generate an dynamic link
Like
localhost://apps/{owncode}/userspace
The owncode is calculated by us an the code will saved into the database
The user can add entries for his userspace.
localhost://apps/{owncode}/entries/new
How can I compare (check is its correct} the {owncode} from the database with the url. Because we want to catch if someone call the url by try and error.
You can't check that without forcing the user to log in. You should also not be using anything in the URL to identify their "userspace." It should all be tucked away in the session, associated with the logged in user's account.
If you at least want to make owncode hard to guess, you could generate a ridiculously long hashed string. But this is not recommended, it would not guarantee any security, and users could still try and guess the strings for other "userspaces" without your app being able to do anything about it.

I want to create an app where I have a table view and when I select a row where inside is written a name (at example "house") it give me in a textView the explanation of its meaning. What's the approach to do this app? I sould use a database as core data? but what's the way to take the text for every word? Can I use txt file or what? Can you help me?
If you want to store the data locally, I'd go either for core db, or xml file, depending on the kind of data. When you create a project in XCode with core data enabled, you can see how the crud is done.
