ABPeoplePickerNavigationController + predicateWithBlock | crash

Question

ABPeoplePickerNavigationController + predicateWithBlock | crash

I have my own PeoplePicker controller that is ported from ABPeoplePickerNavigationController

. I am trying to install NSPredicate

for self.predicateForEnablingPerson

using preidcateWithBlock

as follows:

self.predicateForEnablingPerson = [NSPredicate predicateWithBlock:^BOOL(id evaluatedObject, NSDictionary *bindings) {
        return YES;
    }];

and it crashes with an error:

** Application terminated due to uncaught exception "NSInvalidArgumentException", reason: "NSBlockPredicate could not be encoded or decoded"
