handleWatchKitExtensionRequest is not called - ios

Question

I am trying to launch the parent ios app from watchkit app. I'm using url scheme to launch the app.But it seems like
-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
is nevered called. It seems like watch app does launch the app in backgound. But the parent app does not handle the watchkit request. I tried my approach in a new project and it works perfectly. Is there any thing I need to pay attention?
I've already tried to Debug>Attach to process>myapp and put a breakpoint inside handleWatchKitExtensionRequest method to confirm if it is called and it isn't called.
Here is the progress, I call openParentApplication when a button is clicked in watch app.
#IBAction func viewOniPhoneAction() {
let userInfo: [NSObject : AnyObject] = [
"userID" : user.userID
]
WKInterfaceController.openParentApplication(userInfo, reply: { (userInfo : [NSObject : AnyObject]!, error : NSError!) -> Void in
})
}
Here is my app delegeate
- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void(^)(NSDictionary *replyInfo))reply
{
NSDictionary *replyDict = #{#"response": #"done"};
reply(replyDict);
}
I tried reply() in handleWatchKitExtensionRequest but I got this error in reply block from watch app
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:]}

I got it to work!!! Having the same issue....
Just increase the beginBackgroundTaskWithExpirationHandler time to a larger value if you still don't get the data!!! I used 2 secs previously but my network is too weak!!!
I call openParentApplication when a button is clicked in watch app:
[WKInterfaceController openParentApplication:loadDetailChatDataDictionary reply:^(NSDictionary *replyInfo, NSError *error) {
Here is my app 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
}

handleWatchKitRequest isn't called when you open the app via a URL scheme. It is only called in response to requests made in the WatchKit extension made using openParentApplication:reply:. That's why you aren't seeing it being executed.

You will need to wrap your reply in a background task to ensure your parent app has time to respond.
-
(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *replyInfo))reply{
UIApplication *app = [UIApplication sharedApplication];
UIBackgroundTaskIdentifier bgTask __block = [app beginBackgroundTaskWithName:#"watchAppRequest" expirationHandler:^{
[[UIApplication sharedApplication] endBackgroundTask:bgTask];
bgTask = UIBackgroundTaskInvalid;
}];
//make your calls here to your tasks, when finished, send the reply then terminate the background task
//send reply back to watch
reply(replyInfo);
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 2.0 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[app endBackgroundTask:bgTask];
bgTask=UIBackgroundTaskInvalid;
});
}
