how to save bool value in KeychainItemWrapper

I want to store bool value in KeychainItemWrapper, how to store ?

I have tried this code, but it gives me error.

 [keychain setObject:YES forKey:(__bridge BOOL)kSecAttrIsInvisible];
Solution

  • The BOOL is a primitive type and the setObject:forKey: only excepts classes that derive from NSObject.

    So use NSNumber it has a special method for it + numberWithBool::

    [keychain setObject:[NSNumber numberWithBool:YES] forKey:@"someKey"];

    And if you need to bool again:

     NSNumber *value = [keychain objectForKey:@"someKey"];
 BOOL boolValue = [value boolValue];
