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:

您无法从扩展程序(例如今日"视图)或WatchKit应用程序访问HealthKit."

"You cannot access HealthKit from extensions (like the Today view) or from a WatchKit app."

您可以做的是调用

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

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.
