尝试执行两个 Parse PFQueries 但出现错误 - SWIFT

Question

我目前正在同时执行两个 PFQueries，一个是 PFUser.query，另一个是标准对象查询。它们都试图大致同时执行。在代码运行之前，我没有收到任何错误：

'Cannot do a comparison query for type: Swift._NSSwiftArrayImpl'

我只能假设这是因为我试图同时执行两个不同的查询？

有人可以进一步了解它的含义以及如何克服它吗？

我用于这两个查询的代码是：

    var query = PFQuery(className: "Traits")
            query.whereKey("name", equalTo: self.names)
            var waveUsers = query.findObjects()

            if waveUsers != nil {

                self.profile.waves.removeAll(keepCapacity: true)

            for waveUser in waveUsers{


                    self.profile.waves.append(waveUser["waves"] as Int)
                    }
                }

和 PFUser 查询：

 var query = PFUser.query()
                query.whereKey("location", nearGeoPoint:geopoint)
                query.limit = 20
                var users = query.findObjects()

                if users != nil {

                    self.profile.names.removeAll(keepCapacity: true)
                    self.profile.images.removeAll(keepCapacity: true)
                    self.profile.genders.removeAll(keepCapacity: true)
                    self.profile.locations.removeAll(keepCapacity: true)
                    self.profile.status.removeAll(keepCapacity: true)
                    self.profile.rStatus.removeAll(keepCapacity: true)
                    self.profile.age.removeAll(keepCapacity: true)


                    for user in users {

                       {
                            self.profile.names.append(user["name"] as Int)
                            self.profile.images.append(user["image"] as NSData)
                            self.profile.genders.append(user["gender"] as NSString)
                            self.profile.locations.append(user["location"] as PFGeoPoint)
                            self.profile.rStatus.append(user["relationship"] as NSString)
                            self.profile.age.append(user["age"] as NSInteger)
                            self.profile.status.append(user["status"] as NSString)

                            self.appsTableView.reloadData()

                            user.save()
                    }
                }

如果您想测试 "name" 列是否可以在您的 self.names 数组中找到，请使用 containsAllObjectsInArray:

equalTo 对单个对象进行操作（它可以测试单个对象是否存在于数组类型列中，但您正在尝试相反的方法）。

EDIT - 假设您有一个字符串数组，您想要查找其字符串列可在该数组中找到的对象...

// find people in the People class who were SNL cast members
var array = ["belushi", "akroyd", "radner"];
var queries = [];

// assume underscorejs
_.each(array, function(name) {
    var query = new Parse.Query("People");
    query.equalTo("lastName", name);
    queries.push(query.find());
});
Parse.Query.or(queries).then(function() {
    var snlCastMembers = _.toArray(arguments);
});
