在Apple Watch中调用URL的最佳做法是什么？

Question

What is the best practice to call API from Apple watch

1. use sendMessage "watchConnectivity" from Apple watch to iPhone to call the API

or

2. use NSURLSession to call the API from the watch itself ?

Answer 1

Using the NSURLSession API, the device that performs the request is abstracted from the developer. If the phone is available, it will perform the request on the phone and return it to your watch app as if the watch itself performed the request. If the phone is not available, the watch can perform request on its own if there is a known 2.4 GHz network available.

The answer is NSURLSession. That way you don't have to worry about passing info between the phone and watch with the WatchConnectivity framework, NSURLSession does it for you

Answer 2

苹果公司在WWDC实验室中建议直接从手表使用NSURLSession，所以我建议＃2。
