Sharing parameters between setting view and application view

Question

Hi there, Simple question : I've got an iPhone app with 2 views with each a separated xib files. one view holds the settings of the app one view holds the app using the settings made in previous view.

How should I implement the sharing of setup parameters between the 2 views ? should I manage those parameters in the app delegate ?

Answer 1

You can save the settings in the user defaults using

[[[NSUserDefaults] standardUserDefaults] setObject:blah forKey:@"blah"];

Then in the other view, just get the values from the user defaults with

[[NSUserDefaults] standardUserDefaults] objectForKey:@"blah"];

The NSUserDefaults class keeps the objects in memory and writes them out to disk at certain periods. So you don't have to worry about hitting the disk too often.
