PFObject 在 Xcode 6.0.1、Yosemite GM3 中没有名为“saveInBackground"的成员 [英] PFObject does not have a member named 'saveInBackground' in Xcode 6.0.1, Yosemite GM3

问题描述

Parse 在 Yosemite 中表现得很奇怪，saveInBackground 声称不是 PFObject 的成员.

Parse is acting very strangely in Yosemite, saveInBackground claims to not be a member of PFObject.

var score = PFObject(className: "score")
    score.setObject("Mo", forKey: "name")
    score.setObject(1, forKey: "scoreCount")
    score.saveInBackground()

显然这应该可行，也许这是 Xcode 6.0.1 或 Yosemite GM3(或组合)的问题.需要明确的是，使用 saveInBackgroundWithBlock 工作正常.

Clearly this should work, perhaps it's an issue with Xcode 6.0.1 or Yosemite GM3 (Or a combination). To be clear, using saveInBackgroundWithBlock works fine.

有没有其他人遇到过这个或类似的奇怪错误?

Has anyone else experienced this or a similarly weird bug?

推荐答案

saveInBackground 方法在头中声明，返回一个 BFTask * 对象，它是螺栓框架.确保你的项目链接了 Bolts 框架，然后添加

The saveInBackground method is declared in the header to return a BFTask * object, which is part of the Bolts framework. Make sure your project is linking the Bolts framework, and then add

#import <Bolts/Bolts.h>

到您的桥接头.
