Ios 从Apple Watch应用程序到其他设备的本地网络连接可以在模拟器上工作，但不能在手表上工作

我正在尝试为我的Apple Watch构建一个应用程序，用于远程控制覆盆子Pi上的媒体播放器（omxplayer）

我让它在Xcode的模拟器中工作，但在实际的手表上不工作

在Raspberry Pi上，我有一个简单的python脚本，可以启动TCP服务器并侦听命令

在WatchKit扩展名projet的InterfaceController.m文件中，我有以下代码：

- (IBAction)playPauseButtonPressed {    
    [self initNetworkCommunication];
    [self sendNetworkCommand:@"play"];
    [self closeNetworkCommunication];
}

-(void)initNetworkCommunication {
    CFReadStreamRef readStream;
    CFWriteStreamRef writeStream;

    CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"192.168.10.116", 10010, &readStream, &writeStream);

    if(!CFWriteStreamOpen(writeStream)) {
        NSLog(@"Error, writeStream not open");

        return;
    }

    inputStream = (NSInputStream *)CFBridgingRelease(readStream);
    outputStream = (NSOutputStream *)CFBridgingRelease(writeStream);

    [inputStream setDelegate:self];
    [outputStream setDelegate:self];

    [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];

    [inputStream open];
    [outputStream open];
}

-(void)sendNetworkCommand:(NSString *) command {    
    NSData *data = [[NSData alloc] initWithData:[command dataUsingEncoding:NSASCIIStringEncoding]];
    [outputStream write:[data bytes] maxLength:[data length]];
}

-(void)closeNetworkCommunication {        
    [inputStream close];
    [outputStream close];

    [inputStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [outputStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];

    [inputStream setDelegate:nil];
    [outputStream setDelegate:nil];

    inputStream = nil;
    outputStream = nil;
}

当我按下手表应用程序上的按钮时，会调用“playPauseButtonPressed”功能。此函数启动到Raspberry Pi的网络连接并发送字符串

正如我所说，它可以在手表模拟器上工作，但不能在真正的设备上工作

请注意，在真实设备上的iOS应用程序中也可以使用相同的代码

任何帮助都将不胜感激

好的，我让它工作了。与此同时，我升级到了Watchkit2.0SDK。如果有人感兴趣，以下是我的代码（仍然需要工作）：

手表扩展的extensionelegate.m：

- (void)applicationDidFinishLaunching
{
    // Perform any final initialization of your application.

    if ([WCSession isSupported]) {
        WCSession *session = [WCSession defaultSession];
        session.delegate = self;
        [session activateSession];
    }
}

- (IBAction)playPauseButtonPressed
{
    [self sendCommandToPhone:@"pause"];
}

- (IBAction)seekBackwardButtonPressed
{
    [self sendCommandToPhone:@"seek_backward"];
}

- (IBAction)seekForwardButtonPressed
{
    [self sendCommandToPhone:@"seek_forward"];
}

- (IBAction)subtitleButtonPressed
{
    [self sendCommandToPhone:@"subtitle"];
}

- (void)sendCommandToPhone:(NSString *)command
{
    NSLog(@"sendCommandToPhone called");

    NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys:command, @"command", nil];
    [[WCSession defaultSession] sendMessage:dict
                               replyHandler:^(NSDictionary *replyHandler) {
                               }
                               errorHandler:^(NSError *error) {
                                   NSLog(@"%@", [error localizedDescription]);
                               }
    ];
}

手表分机的InterfaceController.m：

- (void)applicationDidFinishLaunching
{
    // Perform any final initialization of your application.

    if ([WCSession isSupported]) {
        WCSession *session = [WCSession defaultSession];
        session.delegate = self;
        [session activateSession];
    }
}

- (IBAction)playPauseButtonPressed
{
    [self sendCommandToPhone:@"pause"];
}

- (IBAction)seekBackwardButtonPressed
{
    [self sendCommandToPhone:@"seek_backward"];
}

- (IBAction)seekForwardButtonPressed
{
    [self sendCommandToPhone:@"seek_forward"];
}

- (IBAction)subtitleButtonPressed
{
    [self sendCommandToPhone:@"subtitle"];
}

- (void)sendCommandToPhone:(NSString *)command
{
    NSLog(@"sendCommandToPhone called");

    NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys:command, @"command", nil];
    [[WCSession defaultSession] sendMessage:dict
                               replyHandler:^(NSDictionary *replyHandler) {
                               }
                               errorHandler:^(NSError *error) {
                                   NSLog(@"%@", [error localizedDescription]);
                               }
    ];

        [session activateSession];

        NSLog(@"WCSession initialized");
    }
}

// Message received from the watch
- (void)session:(WCSession * _Nonnull)session didReceiveMessage:(NSDictionary<NSString *, id> * _Nonnull)message

现在我可以通过手机和手表控制omxplayer；）

TCP连接的东西在手表上不工作吗？我也有同样的问题，都是在模拟器上工作，但不是在真正的手表上。我不知道，正如我在回答中所写的，我现在使用WCSession与手机应用程序通信，所有的网络逻辑都是从应用程序中完成的
