问题
I want to know if there is anyway to keep my WatchKit app running in the background, or if I can possibly program it to launch (i.e. transfer from inactive state to active state) once a certain condition is fulfilled?
My app is running perfectly while the WK App is open and active, and it even runs fine when the iPhone is asleep, or when the parent iOS app is in BG mode. However, I really need my app to continue running in the background on the watch itself. Is this possible?
回答1:
Not possible. Because Apple Document for watchkit clearly mentions that "WatchKit extensions do not support background execution modes,they run only while the user is interacting with the corresponding app on Apple Watch.".
You can refer apple document Link to Apple Doc
