Question

I have been looking for an answer but not really found what i am looking for.

I have an application and is using NSUserDefaults to store ‘currentGameStatus’ and would like to ask the following questions:

1. How do i check if the NSUserDefaults .plist exists? Need this to determine if i need to create it for the first time and if so fill it with default values

2. Where do i find it on my Mac (running simulator)? Would need to delete it to test if the first run works?

Answer 1

The way I do it is I set a BOOL flag in NSUserDefaults if it doesn’t already exist:

if(![[NSUserDefaults standardUserDefaults] boolForKey:@"firstRun"]) {
   //do initialization stuff here...

   [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"firstRun"];
}
