What's the best way to get a value from NSUserDefaults on app load and store it in a global variable?

NSUserDefaults caches the information to avoid having to open the user’s defaults database each time you need a default value NSUserDefaults Class Reference However, if you really want to have this 'constant' (it won't be a true constant though) do something like this pch: extern NSString *themeString AppDelegate. M: NSString *themeString = nil; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // ... themeString = NSUserDefaults standardUserDefaults objectForKey:@"Theme" copy; // ... }.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
