NSNumber numberWithBool changing the value of boolean from plist file - ios

Question

I have a plist file with the a key APICalls of type boolean set to NO.
I then retrieve this value in my code like this:
NSString *destinationPath= [doumentDirectoryPath stringByAppendingPathComponent:#"DefaultSettings.plist"];
NSMutableDictionary *defaultPreferences = [NSMutableDictionary dictionaryWithContentsOfFile:destinationPath];
NSLog(#"SETUP %#", defaultPreferences);
[[NSUserDefaults standardUserDefaults] registerDefaults:defaultPreferences];
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSMutableArray *tmp = [data objectForKey:#"user"];;
user.email = [tmp valueForKey:#"email"];
user.userId = [tmp valueForKey:#"id"];
user.username = [tmp valueForKey:#"username"];
user.APICall = [NSNumber numberWithBool:[defaults objectForKey:#"APICalls"]];
NSLog(#"API Call Value: %#", user.APICall);
My first log returns :
SETUP {
APICalls = 0;
TrackingTimer = 15;
VoiceMessages = 0;
}
Showing me the value of APICalls is 0.
But when I log user.APICall, I get
API Call Value: 1
Also user.APICall is of type NSNumber.

Answer 1

The problem is that objectForKey: of NSUserDefaults returns a cocoa object - in this case, it is probably an NSNumber. When you pass it to numberWithBool: method, it treats nil as NO, and everything else as YES.
If APICalls is set as a boolean, you can use it directly, like this:
user.APICall = [defaults objectForKey:#"APICalls"];
If APICalls is a number that you would like to re-interpret as a boolean, you can use this line instead:
user.APICall = [NSNumber numberWithBool:[[defaults objectForKey:#"APICalls"] intValue] != 0];

Don't forget to call [userDefaults synchronise].
