Я просматривал примеры в WatchOS 2 По учебнику книги, написанной командой RayWenderlich, в частности главе 18. Все они работают нормально. В моем собственном приложении я пытаюсь отправить кнопку с часами, чтобы запустить кнопку в приложении iPhone. Вот соответствующий код в Swift с вахты и телефона:Отладочный совет для WatchOS2

Я получаю сообщение стрельбу штрафа на Watch и посмотреть их в журнале отладки ... Но они, похоже, не срабатывают на телефоне. Телефон успешно отправляет свои сообщения на часы.
Я тестировал этот код как в симуляторе, так и на собственных часах и iPhone. Обратите внимание, что сообщения с iPhone на Watch выполняются с помощью via updateApplicationContext и отправляемого сообщения, которое я пытаюсь использовать для отправки сообщений с часовых телефонов на iPhone. Вот пример кода iPhone для отправки контекста:
if WCSession.isSupported() {
if session.watchAppInstalled {
let UserInfo = ["waste":Float((wastedAmount.text! as NSString).floatValue), "cost":Float((totalAmount.text! as NSString).floatValue), "counter":Float((peopleInMeeting.text! as NSString).floatValue), "status":"Start"]
do {
try session.updateApplicationContext(UserInfo as! [String : AnyObject])
} catch {
print("Updating the context failed: ")
}
}
}
ли приведение к 'Double' успех? Счетчик звучит так, будто это может быть 'Int'? – stkent
Приведение к двойному успеху. –
На стороне часов вы внедрили 'func session (session: WCSession, didFinishUserInfoTransfer userInfoTransfer: WCSessionUserInfoTransfer, ошибка: NSError?)'? Получает ли он какие-либо обратные вызовы с любыми ошибками? – ccjensen
