/// 通过代理控制选择的联系人或联系人属性
weak public var delegate: CNContactPickerDelegate?

1.3 Predicates For Selecting Contacts

/// 晒选联系人
@NSCopying public var predicateForEnablingContact: NSPredicate? // e.g. emailAddresses.@count > 0

/// 可选得联系人
@NSCopying public var predicateForSelectionOfContact: NSPredicate? // e.g. emailAddresses.@count == 1

/// 可选的联系人属性
@NSCopying public var predicateForSelectionOfProperty: NSPredicate? // e.g. (key == 'emailAddresses') AND (value LIKE '*@apple.com')
