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中表现得非常奇怪，saveInBackground声称自己不是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()

显然这应该有效，也许这是Xcode 6.0.1或Yosemite GM3（或组合）的问题。为了清楚起见，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.

还有其他人遇到过这个或类似奇怪的错误吗？

Has anyone else experienced this or a similarly weird bug?

推荐答案

在标头中声明 saveInBackground 方法以返回 BFTask * 对象，这是Bolts框架的一部分。确保您的项目链接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>

到你的桥接头。

这个为我解决了Swift中的一些缺失API（这个，以及 PFAnalytics.trackAppOpenedWithLaunchOptions 在这里提到：为什么我的PFAnalytics没有trackAppOpeneWithLaunchOptions功能？（IOS SWIFT）

This solved a few "missing" APIs in Swift for me (this one, as well as PFAnalytics.trackAppOpenedWithLaunchOptions mentioned here: Why does my PFAnalytics not have trackAppOpeneWithLaunchOptions function? (IOS SWIFT)
