ios - 在 Parse Cloud Code 中为对象设置 PFFile

Question

是否可以直接将 Swift 中的 PFFiles 传递给 Cloud Code 并将其设置在对象上？

我有一个 PFFile，

let imageData = UIImageJPEGRepresentation(self.imageView.image!, 0.1)
let imageFile = PFFile(data: imageData!)

我正尝试在用户对象上设置它，然后像这样在云代码中注册它:

Parse.Cloud.define("createNewUser", function(request, response) {

    var theimage = request.params.image
    var username = request.params.username
    var pw = request.params.password

    var user = new Parse.User();
    user.set("username", username);
    user.set("password", pw);

    theimage.save().then(function(){
        user.set("image",theimage)
        user.signUp(null, {
        success: function(user) {       
            response.error("working");
        },
        error: function(user, error) {
            response.error("Sorry! " + error.message);
        } });

    }, function(error) {
        response.error("Sorry! " + error.message);
    });

});

调用云代码的iOS代码:

 PFCloud.callFunctionInBackground("createNewUser", withParameters: 
 ["username": username, "password": password, "image": imageFile], 
 block: { (result, error) -> Void in
    // UI stuff
 })

我收到这个错误:

TypeError: Cannot read property 'format' of undefined
at e.a.value (Parse.js:13:25673)
at main.js:40:14 (Code: 141, Version: 1.10.0)

我试着看这个:http://parse.com/docs/js/api/classes/Parse.File.html而且我仍然不确定如何将我的图像从 Swift 获取到云代码，以便我可以注册新用户...

我没有将图像作为 PFFile 传递，而是将图像作为 NSData 传递，随后将结果转换为 Parse.File 对象。然后我保存它并注册了用户。效果不错!

JS

var parseFile = new Parse.File("prof",theimage)

parseFile.save().then(function(){
    user.set("image",parseFile)
    user.signUp(null, {
    success: function(user) {       
        response.success("working");
    },
    error: function(user, error) {
        response.error("Sorry! " + error.message);
    } });

}, function(error) {
    response.error("Sorry! " + error.message);
});
