ios - 未调用 handleWatchKitExtensionRequest

Question

我正在尝试从 watchkit 应用程序启动父 ios 应用程序。我正在使用 url scheme 来启动应用程序。但它看起来像

-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply 

从未被调用。似乎 watch 应用程序确实在后台启动了该应用程序。但是父应用程序不处理 watchkit 请求。我在一个新项目中尝试了我的方法，并且效果很好。有什么需要注意的吗？

我已经尝试调试>附加到进程>myapp 并在 handleWatchKitExtensionRequest 方法中放置一个断点以确认它是否被调用和未被调用。

这是进度，在 watch 应用中单击按钮时我调用 openParentApplication。

@IBAction func viewOniPhoneAction() {


    let userInfo: [NSObject : AnyObject] = [
        "userID" : user.userID
    ]


    WKInterfaceController.openParentApplication(userInfo, reply: { (userInfo : [NSObject : AnyObject]!, error : NSError!) -> Void in

    })

}

这是我的应用委托(delegate)

- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void(^)(NSDictionary *replyInfo))reply
{
NSDictionary *replyDict = @{@"response": @"done"};
reply(replyDict);
}

我在 handleWatchKitExtensionRequest 中尝试了 reply() 但我在 watch 应用程序的回复 block 中遇到了这个错误

Error Error Domain=com.apple.watchkit.errors Code=2 "The UIApplicationDelegate in the iPhone App never called reply() in -[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]" UserInfo=0x60800026e0c0 {NSLocalizedDescription=The UIApplicationDelegate in the iPhone App never called reply() in -[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]}

我成功了!!!有同样的问题....

如果仍然没有得到数据，只需将 beginBackgroundTaskWithExpirationHandler 时间增加到一个更大的值!!!我之前用了 2 秒，但是我的网络太弱了!!!

我在 watch 应用程序中单击按钮时调用 openParentApplication:

[WKInterfaceController openParentApplication:loadDetailChatDataDictionary reply:^(NSDictionary *replyInfo, NSError *error) {

这是我的应用委托(delegate):

- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply {

    __block UIBackgroundTaskIdentifier bogusWorkaroundTask;
    bogusWorkaroundTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{
        [[UIApplication sharedApplication] endBackgroundTask:bogusWorkaroundTask];
    }];
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ // increase the time to a larger value if you still don't get the data!!! I used 2 secs previously but my network is too weak!!!
        [[UIApplication sharedApplication] endBackgroundTask:bogusWorkaroundTask];
    });
    // --------------------

    __block UIBackgroundTaskIdentifier realBackgroundTask;
    realBackgroundTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{
        reply(nil);
        [[UIApplication sharedApplication] endBackgroundTask:realBackgroundTask];
    }];

    NSString *value = userInfo[@"key"];
    if ([value isEqualToString:@"loadRecentChatData"]) {
                 reply(@{@"recents":recents}); // Add your reply here
    }
