关闭/停用WCSession [英] Close/Deactivate WCSession

问题描述

我正在开发具有手表扩展功能(watchOS 2)的iPhone应用程序(iOS 9 beta)，并将数据从手表传递到手机，我正在使用WCSession.

I am developing an iPhone app (iOS 9 beta) with watch extension (watchOS 2), and to pass the data from watch to phone I am using WCSession.

我有2个使用WCSession的不同视图控制器，因此对于每个控制器，我都实例化了新的WCSession对象.对于第一个视图控制器来说，它工作正常，但是当我想在第二个视图控制器中接收消息时，仍然很少有初始消息发送到第一个视图控制器.

I have 2 different view controllers using WCSessions, so for each of the controller I am instantiating new WCSession object. For the first view controller it works fine, but when I want to receive messages in second view controller, few initial messages are still being sent to first controller.

在转到第二个控制器之前，有什么方法可以停用/禁用第一个视图控制器的会话?还是我还应该考虑其他选择?

Is there any way I can deactivate / disable session of first view controller before going to second controller? Or are there any other options I should look into?

谢谢！

推荐答案

来回传递数据时，您正在发送字典.如果您指定好键，则可以为每个ViewController获取适当的数据.

When you are passing data back and forth you are sending Dictionaries. If you specify good keys you could get the appropriate data for each ViewController.

示例:

ViewController1:

ViewController1:

[session updateApplicationContext:@{@"viewController1": @"item1"} error:&error];

ViewController2:

ViewController2:

[session updateApplicationContext:@{@"viewController2": @"item2"} error:&error];

接收数据时:

- (void) session:(nonnull WCSession *)session didReceiveApplicationContext:(nonnull NSDictionary<NSString *,id> *)applicationContext {

    if ([applicationContext objectForKey:@"viewController1"]) {
        //ViewController1 data
    } else if ([applicationContext objectForKey:@"viewController2"]) {
        //ViewController2 data
    }
}
