How to use WCSession didReceiveMessage to receive different messages?

Question

I need to send different messages from different buttons. How do I use didReceiveMessage to receive them all?

Answer 1

didReceiveMessage being called

According to Apple:

didReceiveMessage is called every time a new mesage is received from WatchConnectivity on Apple Watch.

You could use its argument to check the message, and you could add an entry to the dictionary passed by WCSession to check the source. For example if the argument is called message, you can use the following code:

Swift

switch message["source"] {
    case "button1" : print("Source is button 1")
    case "button2" : print("Source is button 2")
    default : break
}

Objective-C

switch (message[@"source"]){
    case @"button1" : NSLog(@"Source is button 1"); break;
    case @"button2" : NSLog(@"Source is button 2"); break;
}

So you could use one didReceiveMessage method to receive all different messages from different buttons.

Conclusion

1- didReceiveMessage is called every time a message is coming.

2- You could use its argument to check the message.

3- You could use one didReceiveMessage method to receive all different messages from different buttons.
