Question

I have an apps that load a json from a remote server, using a NSURLConnection. Once it has finished loading (calling connectionDidFinishLoading), I want to record if it was the first launch of the application.
So in connectionDidFinishLoading I did that :

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
BOOL firstLaunch = [defaults boolForKey:@"screen_firstLaunch"];
NSLog(@"First launch : %d",firstLaunch);
[defaults setBool:YES forKey:@"screen_firstLaunch"];

And it displays “First launch : 0” every time ….

So I thought it might be because it’s on another thread, so I try to deport the code into a function that I call in connectionDidFinishLoading using performSelectorOnMainThread, but I get the same result …

Please someone help me, I’m going mad !

Remember to call [defaults synchronize]; after setting your key in the defaults.
