Answer 1

In your application delegate’s -applicationWillTerminate:, save the info by e.g.

....
NSUserDefaults* defs = [NSUserDefaults standardUserDefaults];
[defs setObject:myFirstTextField.text forKey:@"firstTextField"];
[defs setObject:mySecondTextField.text forKey:@"firstTextField"];
...

And in -applicationDidFinishLaunching: or -application:didFinishLaunchingWithOptions:, restore the info by

....
NSUserDefaults* defs = [NSUserDefaults standardUserDefaults];
myFirstTextField.text = [defs stringForKey:@"firstTextField"];
mySecondTextField.text = [defs stringForKey:@"firstSecondField"];
...

In general, whatever you want to save and restore can be placed into NSUserDefaults.
