ios - "The UIApplicationDelegate in the iPhone App never called reply() in -[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]"

Question

好的，我正在制作这个 Apple Watch 应用，在我的 Watch 应用中，我有一个按钮。当您触摸按钮时，它会执行以下操作:

[WKInterfaceController openParentApplication:[NSDictionary dictionary] reply:^(NSDictionary *replyInfo, NSError *error) {
    if(error) {
        NSLog(@"%@",error);
    }
}];

在我的应用程序委托(delegate)文件中，我执行以下操作:

-(void) application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply {
    //Code that is not importent and is confidential
    reply([NSDictionary dictionary]);
}

但是，当我按下按钮时，我收到此错误:

Error Domain=com.apple.watchkit.errors Code=2 "The UIApplicationDelegate in the iPhone App never called reply() in -[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]" UserInfo=0x7fd2b9c35ae0 {NSLocalizedDescription=The UIApplicationDelegate in the iPhone App never called reply() in -[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]}

我正在调用 reply() 如上所示，但它没有看到这一点!另外，它忽略了我在那里的其他代码!

谁能解释一下为什么会发生这种情况？

来自文档:

replyInfo: A dictionary containing data to return to the WatchKit app. The contents of the dictionary must be serializable to a property list file. The contents of this dictionary are at your discretion and you may specify nil.
