我尝试在我的 iPhone 应用程序中使用 AVAudioPlayer 播放音频文件，我希望在手表上调用此函数.

I try to play an audio file with AVAudioPlayer in my iPhone app and I expect that this function will be called on watches.

也许我应该做一些额外的调用来触发这个功能?除了苹果文档中所说的之外，我找不到有关此方法的任何其他信息.

Maybe I should make some additional call to trigger this function? I cannot find any additional information about this method except what is said in the apple documentation.
