I am making a iWatch app where I need to show data from healthkit. is it possible to access healthkit APIs from iWatch extension?
推荐答案
否. HealthKit框架参考:
您可以做的是调用 openParentApplication:reply:与iPhone应用程序本身进行对话并检索该数据.搜索该方法名称，您将找到一些有关如何调用该方法并将其从其中返回数据的示例.
What you can do is call openParentApplication:reply: to talk to the iPhone app itself and retrieve that data. Search around for that method name and you'll find some examples on how to call it and get data back to the Watch from it.
更新:正如下面其他人提到的，watchOS 2的情况已更改.该文档尚未更新，但请查看 WWDC 2015视频(适用于HealthKit)和观看部分可用于Xcode 7 Beta的代码段.
UPDATE: As others have mentioned below, this has changed for watchOS 2. The documentation has not been updated yet, but check out the WWDC 2015 videos for HealthKit and the Watch for some snippets of code you can use with the Xcode 7 beta.
