Simplest iPhone persistence

NSUserDefaults is ludicrously simple:


//load defaults
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

//persist value
[defaults setObject:@"felix" forKey:@"Username"];

//retrieve value
[[NSUserDefaults standardUserDefaults] stringForKey:@"Username"];

NameError (uninitialized constant ApplicationController):


Fix was simple:


rake rails:update
