Question

I save a bool value in NSUserDefaults like this:

[[NSUserDefaults standardUserDefaults]setBool:NO forKey:@"password"];

And then I synchronize defaults like this:

[[NSUserDefaults standardUserDefaults]synchronize];

But when my app enters background and then enters foreground my bool changes value to YES

Why does that happen ? I set my bool to YES only in one place in program, which is not managing when my app leaves/enters foreground.

Thanks!

Just perform a simple test where you are saving your bool as

[[NSUserDefaults standardUserDefaults]setBool:NO forKey:@"password"];
[[NSUserDefaults standardUserDefaults]synchronize];
NSLog(@"%d",[[NSUserDefaults standardUserDefaults] boolForKey:@"password"]);

see what’s the value..
