I want to create one button in watch and while tapping on watch start one process to my ios app. How can I send the data between 2 devices
[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(sayHello:) name: @"sayHelloNotification" object: nil];
[[NSNotificationCenter defaultCenter] postNotificationName: @"sayHelloNotification" object: nil];
AFAIK, you can not share data directly, like send some datas between them.
What you can do is write data to same file.
