WCSession蘋果手錶無法正常工作

Question

我的XCode 7，iPhone6與iOS 9.1，蘋果手錶WatchOS 2.0（現在我更新到2.0.1）

我儘量讓觀看和iPhone之間的通信。

在iPhone上我初始化我單身

- (instancetype)init { 
    self = [super init]; 
    if (self.isConnectivityAvailable) { 
     session = [WCSession defaultSession]; 
     session.delegate = self; 
     [session activateSession]; 
    } 
    return self; 
} 

- (BOOL)isConnectivityAvailable { 
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"9.0")) { 
     return [WCSession isSupported]; 
    } else { 
     return NO; 
    } 
} 

中的AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    //custom code 
    (void)[AppConnectivityHandler instance]; //start App connectivity with Apple Watch 
    return YES; 
} 

它就是這樣

- (void)session:(WCSession *)session didReceiveMessage:(NSDictionary<NSString *,id> *)message replyHandler:(void (^)(NSDictionary<NSString *,id> * _Nonnull))replyHandler { 
    LOG(@"receive message"); 
    NSString *request = message[kRequestKey]; 
    __block NSDictionary *reply = @{}; 
    dispatch_sync(dispatch_get_main_queue(), ^{ 
     if ([request isEqualToString:kRequestDayInfo]) { 
      //formirate reply dictionary 
     } 
    }); 
    LOG(@"send reply"); 
    replyHandler(reply); 
} 

在我的收藏都是不錯

我處理消息我開始loa在我的主接口控制器

- (void)willActivate { 
    [super willActivate]; 
    if ([WatchConnectivityHandler instance].isConnectivityAvailable) { 
     [[WatchConnectivityHandler instance] loadDayInfoWithCompletion:^(NSError * _Nullable error, WatchDayInfo * _Nullable dayInfo) { 
      //code 
     }]; 
    } else { 
     //error 
    } 
} 

我的手錶單身調用函數時d

+ (nonnull instancetype)instance { 
    static WatchConnectivityHandler *instance; 
    static dispatch_once_t onceToken; 
    dispatch_once(&onceToken, ^{ 
     instance = [WatchConnectivityHandler new]; 
    }); 
    return instance; 
} 

- (instancetype)init { 
    self = [super init]; 
    if (self.isConnectivityAvailable) { 
     session = [WCSession defaultSession]; 
     session.delegate = self; 
     [session activateSession]; 
    } 
    return self; 
} 

- (BOOL)isConnectivityAvailable { 
    return [WCSession isSupported]; 
} 
- (void)loadDayInfoWithCompletion:(void(^ _Nonnull)(NSError * _Nullable error, WatchDayInfo * _Nullable dayInfo))completion { 
    [session sendMessage:@{kRequestKey : kRequestDayInfo} replyHandler:^(NSDictionary<NSString *,id> * _Nonnull replyMessage) { 
     NSLog(@"reply"); 
     dispatch_sync(dispatch_get_main_queue(), ^{ 
      NSLog(@"%@", replyMessage); 
      //custom code 
      completion(nil, /*custom object*/); 
     }); 
    } errorHandler:^(NSError * _Nonnull error) { 
     NSLog(@"error"); 
     dispatch_sync(dispatch_get_main_queue(), ^{ 
      NSLog(@"%@", error); 
      completion(error, nil); 
     }); 
    }]; 
} 

因此，在第一次工作得很好，我也得到答覆。但後來我開始有很多錯誤的像

Error Domain=WCErrorDomain Code=7007 "WatchConnectivity session on paired device is not reachable." 


Error Domain=WCErrorDomain Code=7014 "Payload could not be delivered." 

我的觀察測試，這是經常的問題得到答覆，形成我的iPhone，它等待很長。但在iPhone上測試時，當它收到來自Watch的消息時，它會很快發送回覆，但我在Watch上看不到該回復。

每當手錶啓動我的應用時，我都需要更新我的信息。什麼問題？也許我使用不正確的功能？

使用transeruserinfo方法而不是sendmessage並使用didreceiveuserinfo方法而不是didreceiveapplicationcontext。
