Question

我有一个ABPeoplePickerNavigationController，如下所示

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
    picker.peoplePickerDelegate = self;

我需要禁用从ABPeoplePickerNavigationController的列表视图中选择的一些联系人。

在浏览时，有这样的想法

// Predicate to enable only the contacts having a mail id atleast.
picker.predicateForEnablingPerson = [NSPredicate predicateWithFormat:@"emailAddresses.@count > 0"];

所以我实现了一个类似下面的谓词，以排除我所拥有的第一个名字的联系人选择。

NSString *firstName = @"Kate";

// Predicate to disable selection of the contacts with the first name given.
    picker.predicateForEnablingPerson = [NSPredicate predicateWithFormat:@"firstName != %@",firstName];

不幸的是它没有用。
