NSPredicate 与领域中的任何

Question

我在 Realm 中使用 NSPredicate 时出现异常：

Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: 'Unable to parse the format string "ANY phones.number CONTAINS %@)"'

人 class:

class Person: RLMObject {
    ...
    dynamic var phones = RLMArray(objectClassName: Phone.className())
}

Phone class:

class Phone: RLMObject {

    dynamic var number = ""
    dynamic var formattedNumber = ""

}

和phone构造的谓词：

func phonesPredicate(#searchString:String) -> NSPredicate {

    let searchPredicate = NSPredicate(format: "ANY phones.number CONTAINS %@)", searchString)

return searchPredicate
}

您的格式字符串中有一个错误的右括号。
