确定手表是否蓝牙配对、wifi 或需要使用蜂窝目标 c Xcode

如何解决确定手表是否蓝牙配对、wifi 或需要使用蜂窝目标 c Xcode

我有一个带有 AppleWatch 扩展的应用。我使用蓝牙和 CloudKit 将数据从应用程序传递到手表。我试图找到如何确定手表是否使用蓝牙配对，以便我可以通过这种方式发送数据，或者它是否在 wifi 或蜂窝网络上以通过 CloudKit 获取数据。 我已经导入了 WatchKit 和 CloudKit 并观看了连接。但我似乎无法在目标 c 中找到代码来做出决定，因此我可以使用从正确来源获取数据。

这是我的一些插入 if 语句的代码（不正确，但我想做的例子。

- (void)awakeWithContext:(id)context {
    [super awakeWithContext:context];
  

    if ([WCSession isSupported]) {

        WCSession *session = [WCSession defaultSession];

        session.delegate = self;

        [session activateSession];
        
        NSLog(@"THISIS CALLED");
    }
    // Configure interface objects here.
}
-(void)session:(WCSession *)session didReceiveApplicationContext:(NSDictionary<NSString *,id> *)applicationContext {
    NSLog(@"THIS IS BEING CALLED4");
    
   
    
    if (session==paired)
        //do this

谁能告诉我怎么做，或者给我一个例子或教程。
