如何在iPhone应用程序和applewatch之间共享数据？

Question

关于从iPhone应用程序到苹果手表的共享数据,我遇到了问题.我尝试下面的代码来分享NSMutablearray到苹果手表,但它无法正常工作.

NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:arrStartScore];
NSUserDefaults *defaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.test.StartScore"];
[defaults setObject:encodedObject forKey:@"WatchHomeViewTableList"];
[defaults synchronize];

用于将数据检索到Apple Watch

NSUserDefaults *myDefaults = [[NSUserDefaults alloc]                                 initWithSuiteName:@"group.com.test.StartScoreCheck"];

arrStartScore = [myDefaults objectForKey:@"WatchHomeViewTableList"];
NSLog(@"dict....%@",arrStartScore);

要将数据从手机发送到手表,请使用此代码.

WCSession *session = [WCSession defaultSession];
NSError *error;

[session updateApplicationContext:@{@"message": yourArray} error:&error];

要从手表上的手机接收数据:

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

您可以使用didReceiveApplicationContext访问您的数组

  [applicationContext objectForKey:@"message"];
