我一直在使用WCSession的NatashaTheRobot單例，但無法使sendMessage正常工作。sendMessage問題 - WatchConnectivity
我的目標是從Watch應用程序發送消息到iOS應用程序，並從iOS應用程序傳送字典到應用程序。
這是我在ExtensionDelegate代碼
import WatchKit
import WatchConnectivity
class ExtensionDelegate: NSObject, WKExtensionDelegate, WCSessionDelegate {
var session:WCSession!
var boolCheck = Int()
func applicationDidFinishLaunching() {
WatchSessionManager.sharedManager.startSession()
print("Here i am")
}
func applicationDidBecomeActive() {
print("I AWOKE")
}
func applicationWillResignActive() {
}
}
class WatchSessionManager: NSObject, WCSessionDelegate {
static let sharedManager = WatchSessionManager()
private override init() {
super.init()
}
private let session: WCSession = WCSession.defaultSession()
func startSession() {
session.delegate = self
session.activateSession()
if WCSession.isSupported(){
self.session.sendMessage(["b":"peek"], replyHandler: nil, errorHandler: nil)
print("works")
} else {
print("don't work")
}
func session(session: WCSession, didReceiveMessage message: [String : AnyObject]) {
let sweetN = message["b"]! as? String
dispatch_async(dispatch_get_main_queue(), {
if sweetN == "insertData1" {
NSNotificationCenter.defaultCenter().postNotificationName("sweetData1", object: nil)
})
}
func sendMessage(message: [String : AnyObject],
replyHandler: (([String : AnyObject]) -> Void)? = nil,
errorHandler: ((NSError) -> Void)? = nil)
{
session.sendMessage(message, replyHandler: replyHandler, errorHandler: errorHandler)
print("this is message \(replyHandler)")
var pretty = replyHandler
}
這是我在WCSingleton iOS應用程式碼（單獨從AppDelegate中）
import WatchConnectivity
@available(iOS 9.0, *)
class WatchSessionManager: NSObject, WCSessionDelegate {
static let sharedManager = WatchSessionManager()
private override init() {
super.init()
}
private let session: WCSession? = WCSession.isSupported() ? WCSession.defaultSession() : nil
private var validSession: WCSession? {
if let session = session where session.paired && session.watchAppInstalled {
return session
}
return nil
}
func startSession() {
session?.delegate = self
session?.activateSession()
}
func session(session: WCSession, didReceiveMessage message: [String : AnyObject]) {
//receieve messages from watch
print(message["b"]! as? String)
let sweetN = message["b"]! as? String
dispatch_async(dispatch_get_main_queue(), {
if sweetN == "peek"{
NSNotificationCenter.defaultCenter().postNotificationName("giveMeInfo", object: nil)
}
}
})
}
@available(iOS 9.0, *)
extension WatchSessionManager {
func sendMessage(message: [String : AnyObject],
replyHandler: (([String : AnyObject]) -> Void)? = nil,
errorHandler: ((NSError) -> Void)? = nil)
{
session!.sendMessage(message, replyHandler: replyHandler, errorHandler: errorHandler)
}
}
，這裏是我使用的方法在ViewController（從NSNotificationCenter發射）。然而，這部分代碼永遠不會被執行（這很奇怪，因爲當我使用applicationContext時它可以完美地工作）。
func giveMeInfo(){
let linesAdd1 = linesAdd as! AnyObject
WatchSessionManager.sharedManager.sendMessage(["a":linesAdd1])
}
任何有關如何讓所有這些零件一起工作的見解非常受歡迎！
