Parse.com-从Cloud Code函数返回多个值

Question

I'm trying to create a Cloud Code function which will return multiple values. Now what I'm doing is

response.success({val1 : scores1, val2: scores2});

And according to the Cloud Code logs everything going well. But what I don't know is what kind of object I should cast it when I handle function in my Swift code.

    PFCloud.callFunctionInBackground("myFunction", withParameters: ["value" : 1) { (object:AnyObject?, error:NSError?) -> Void in
       //what I should cast object for
    }

I also have a thought it my mind that it can be a wrong approach as of I'm basically trying to find Swift equivavelnt to a javascript object. If so, is there any other way of returning multiple values from Cloud Code function?

I have the following in my console log when I println the object.

Optional({
poetry = 1;
rap = 9;
})

Answer 1

Just return one object that has properties for each return value or an array of values or a dictionary (or whatever floats your boat ;)) and deserialize it on the client. This way you only have one return value that contains all the data you need conveniently massaged in to an object/list/dictionary/whatever...

PFCloud.callFunctionInBackground("myFunction", withParameters: ["value" : 1) { (object:AnyObject?, error:NSError?) -> Void in
    if let values = object as! [String:Int] {
    // Do something
    }
}

should work

Answer 2

Ok, then your Object is an Dictionary Optional... You can use this Code:

if let responseJSON: [String: Int] = object as? [String: Int] {
      let poetryValue: Int = object["poetry"] as Int
      let rapValue: Int = object["rap"] as Int
}
