我无法存储或读取NSUserDefaults

Question

It seems something is going wrong, I can't store or read NSUserDefaults in my code:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

NSArray * defaultKeys = [NSArray arrayWithObjects:
                                    @"FirstViewComposer",
                                    @"ProfileNickname",
                                    @"ProfileGender",
                                    @"ProfileDateOfBirth",
                                    @"ProfileFavoriteColor",
                                    @"ProfileHeight",
                                    nil];


NSArray * defaultValues = [NSArray arrayWithObjects:
                                    @"YES",
                                    @"Me",
                                    @"Male",
                                    @"08 Dec 1983"
                                    @"Red",
                                    @"183",
                                    nil];

 NSDictionary *appDefaults = [NSDictionary dictionaryWithObject:defaultValues forKey:defaultKeys];


 [defaults registerDefaults:appDefaults];

 NSLog(@"%@", [defaults stringForKey:@"FirstViewComposer"]); //null

thanks

UPDATE : Now I'm synchronized, actually they are stored but I'm probably not retrieving them correctly:

You have to synchronize your data before retrieve them from disk. To do so you should use synchronize method.

UPDATE: You should change the way you try to store your appDefaults NSDictionary. Try:

#define kAppDefaultEnty @"AppDefaultsEntry"
[defaults setObject:appDefaults forKey:kAppDefaultEnty];

And then synchronize it:

[defaults synchronize];
