Przeglądam przykłady w książce WatchOS 2 By Tutorial zespołu RayWenderlich, w szczególności rozdział 18. Wszystkie działają poprawnie. W mojej własnej aplikacji próbuję wysłać naciśnięcie przycisku z zegarka, aby uruchomić przycisk na aplikacji na iPhone'a. Oto odpowiedni kod w Swift z zegarka i telefonu:Porada dotycząca debugowania dla WatchOS2

replyHandler(reply)
}
if let status = message["status"] as? String {
if status == "Start" {
let reply = ["status":"Quorum"]
meetingStartedButtonPressed(self)
replyHandler(reply)
}
if status == "Quorum" {
let reply = ["status": "Finish"]

replyHandler(reply)
}
if status == "Finish" {

dostaję komunikaty wypalania porządku na zegarku i zobacz je w dzienniku debugowania ... Ale nie wydają się strzelać przez telefon. Telefon pomyślnie wysyła wiadomości do zegarka.
Testowałem ten kod zarówno w symulatorze, jak i na moim własnym zegarku i telefonie iPhone. Zauważ, że wiadomości z iPhone'a do Watch są wykonywane za pomocą via updateApplicationContext a wiadomość wysyłania, której próbuję użyć, aby wysyłać wiadomości z zegarka na iPhone'a. Oto przykładowy kod iPhone dla wysyłającego kontekstu:
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: ")
}
}
}
Czy oddanych do 'Double' sukces? Licznik brzmi, jakby to był "Int". – stkent
Rzucanie do Doublea kończy się sukcesem. –
Po stronie oglądania, czy zaimplementowałeś 'func session (session: WCSession, didFinishUserInfoTransfer userInfoTransfer: WCSessionUserInfoTransfer, error: NSError?)'? Czy otrzyma jakiekolwiek wywołania zwrotne z błędami? – ccjensen
