SRM*_*RMR 3 iphone ios swift watchkit
我已经在模拟器和设备上进行了测试,不知何故手表连接停止工作在使用一次后。
我正在从Watch -> iPhone传递数据,它只能工作一次,然后停止。
有任何想法吗?
苹果手机ViewController:
var session: WCSession?
override func viewDidLoad() {
super.viewDidLoad()
if WCSession.isSupported() {
session = WCSession.default()
session?.delegate = self
session?.activate()
}
}
func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) {
// Received Application Context from Watch
let type = applicationContext["watchType"]
print("Type iPhone: \(type)")
DispatchQueue.main.async {
self.type.text = "Type: \(type)"
}
}

观看InterfaceController:
let session = WCSession.default()
override func awake(withContext context: Any?) {
super.awake(withContext: context)
if WCSession.isSupported() {
session.delegate = self
session.activate()
}
}
@IBAction func startPressed() {
saveEverything()
}
func saveEverything() {
let watchContextType = ["watchType" : "Boxing/Running"]
do {
print("Type Watch: \(watchContextType)")
try session.updateApplicationContext(watchContextType)
} catch {
print("Didn't work")
}
}

使用的时候updateApplicationContext(),每次调用都需要修改参数,否则msg不会投递。我相信这是为了节省电池。
无论如何,尝试使用sendMessage()或发送您的消息sendMessageData(),然后每次都会发送消息,即使它们具有相同的内容。而且,它们的优先级高于updateApplicationContext所以这是双赢的:)
