Question

模型

使用代码：

class News: Object {
dynamic var ExternalId: String?
dynamic var Title: String?
dynamic var Preview: String?
dynamic var Description: String?
dynamic var PublicationDate: Date?
dynamic var ExternalUrl: String?
dynamic var ImageUrl: String?
dynamic var ViewTypeName: String?
dynamic var Status: Bool = true
dynamic var Like: Bool = false
dynamic var AuthorizedOnly: Bool = false

override static func primaryKey() -> String? {
    return "ExternalId"
}

错误：

***由于未捕获的异常终止应用＆＃39; NSInvalidArgumentException＆＃39;，原因：＆＃39;无法解析格式字符串＆＃34;赞= = YES＆＃34;＆＃39;

我试试：

self.news = try! Realm().objects(News.self).filter("Like == YES").sorted(byProperty: "PublicationDate", ascending: true)

但它没有用！

请帮忙！

似乎NSPredicate将Like视为关键字而不是属性名称。作为一种解决方法，您可以使用类似的东西：

.filter(NSPredicate(format: "%K == true", "Like"))

无法解析RealmSwift中的格式字符串
