Question

我有以下两个模型（用户和项目）：

class User: Object {    // Users that logged in app in specific device atleast once
    @objc dynamic var serverId: Int = 0
    @objc dynamic var firstName: String = ""
    @objc dynamic var lastName: String = ""
    @objc dynamic var email: String?
    @objc dynamic var company: String?
    @objc dynamic var phoneNumber: String = ""
    @objc dynamic var syncBaseTime: String = ""

    let projects = LinkingObjects(fromType: Project.self, property: "user")

    convenience init(_serverId: Int, _firstName: String, _lastName: String, _phoneNumber: String) {
        self.init()

        self.serverId = _serverId
        self.firstName = _firstName
        self.lastName = _lastName
        self.phoneNumber = _phoneNumber
    }

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

class Project: Object {
    @objc dynamic var serverId: Int = 0
    @objc dynamic var name: String = ""
    @objc dynamic var stateId: Int = 0
    @objc dynamic var stateName: String = ""
    @objc dynamic var cityId: Int = 0
    @objc dynamic var cityName: String = ""

    @objc dynamic var user: User?
    @objc dynamic var isOwner: Bool = false
    @objc dynamic var isActive: Bool = false
    @objc dynamic var compoundKey: String = ""
    @objc dynamic var syncDetailTime: String = ""

    let accountTitles = LinkingObjects(fromType: AccountTitle.self, property: "project")
    let notes = LinkingObjects(fromType: Note.self, property: "project")

    convenience init(_serverId: Int, _name: String, _stateId: Int, _stateName: String,
                 _cityId: Int, _cityName: String, _user: User, _isOwner: Bool, _isActive: Bool) {
        self.init()

        self.serverId = _serverId
        self.name = _name
        self.stateId = _stateId
        self.stateName = _stateName
        self.cityId = _cityId
        self.cityName = _cityName

        self.user = _user
        self.isOwner = _isOwner
        self.isActive = _isActive
        self.compoundKey = "\(self.user!.serverId)-\(self.serverId)"
    }

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

当我想对它们执行查询并获取当前用户正在使用它们的项目，但当前未选择它们时，会出现问题：

self.realm.objects(Project.self).filter(NSPredicate(format: "user.serverId == %@ && isActive == true && serverId != %@", self.currentUser.serverId, self.currentProject.serverId))

我收到此错误，没有来自Xcode的更多信息：

Thread 1: EXC_BAD_ACCESS (code=1, address=0x11)

我找不到我的错误在哪里，对此我将不胜感激。

您在格式字符串中使用了错误的说明符，local对于对象仅，而%@不是Int < / p>

将NSPredicate用于%ld

Int

注意：这是Swift。请不要在下划线字符前使用难看的 objective-c-ish 变量名。 self.realm.objects(Project.self).filter(NSPredicate(format: "user.serverId == %ld && isActive == true && serverId != %ld", self.currentUser.serverId, self.currentProject.serverId))确实可以编译。

快速获取领域查询中的线程1：EXC_BAD_ACCESS（代码= 1，地址= 0x11）
