ios - Apple Watch openparentapplication : reply: receives Error Domain=FBSOpenApplicationErrorDomain Code=5

Question

我为 Apple Watch 创建了一个较小的项目，以与其运行的父应用程序进行通信。

所以我在我现有的 iOS 项目中创建了一个 Watch 套件扩展，但是当它从 Watch 端调用 openparent 应用程序时，它会在收到的回复 block 中调用

“Error: Error Domain=FBSOpenApplicationErrorDomain Code=5 “操作无法完成。(FBSOpenApplicationErrorDomain 错误 5.)。

这个错误是什么意思？有什么目标问题吗？请在下面找到代码:

watch 套件方面:

- (IBAction)satusButtonClicked {

    NSLog(@"StausButtonClicked");
    NSDictionary *senddict=[[NSDictionary alloc] initWithObjects:@[@"5",@"Two",@"Three"] forKeys:@[@"1",@"2",@"3"]];
    [InterfaceController openParentApplication:senddict reply:^(NSDictionary *replyInfo, NSError *error) {
        NSLog(@"ReplyReceived : %lu",(unsigned long)[replyInfo count]);
        NSLog(@"Reply Info: %@", replyInfo);
        NSLog(@"Error: %@", error);
    }];

}

iOS 端:

-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
    NSLog(@"Watckit call received");
    reply(@{@"Score": @"234"});

Answer 1

In the info.plist, I had "Application Does Not Run in Background" set to YES. This caused the problem. Changing that setting to NO fixed it.

从这里回答: iOS Error: FBSOpenApplicationErrorDomain error 5. What does this mean?
