is it possible to call API through Glance apple watch using NSUserActivity - ios

Question

as apple suggested use Handoff in Glance .
I wants to call web API in Glance Interface , for this I did following things
- (void)awakeWithContext:(id)context
{
[super awakeWithContext:context];
[self CreateUaerActivity];
}
-(void)CreateUaerActivity
{
NSUserActivity *activity = [[NSUserActivity alloc] initWithActivityType:#"com.xxx.xxx.glance"];
activity.title = #"Glance";
activity.delegate=self;
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:kUserLoginWatchKit,kRequestTypeWatchKit, nil];
activity.userInfo = dict;
self.userActivity = activity;
[self.userActivity becomeCurrent];
}
- (void)willActivate
{
[super willActivate];
[NSTimer scheduledTimerWithTimeInterval:120 target:self selector:#selector(doSomething) userInfo:nil repeats:YES];
}
-(void)doSomething
{
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:kUserLoginWatchKit,kRequestTypeWatchKit, nil];
[super updateUserActivity:#"com.xxx.xxx.glance" userInfo:dict webpageURL:nil];
}
-(void)handleUserActivity:(NSDictionary *)userInfo
{
//displaying data
}
and in AppDelegate.m file -
-(BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray *))restorationHandler
{
NSLog(#"Handoff dictionary: %#", userActivity.userInfo);
NSString *requestType = userActivity.userInfo[kRequestTypeWatchKit];
if ([requestType isEqual: kGlanceDataWatchKit])
{
//calling web API to get Data
}
return YES;
}
I found AppDelegate never called continueUserActivity method to return something to Glance interface.
please guide me how to call API through Glance Interface.

I'm not sure if this is what you want, but if you want to call an web Api i suggest yout to do it like this :
in the GlanceInterfaceController :
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
[dictionary setObject:#"getSomething" forKey:#"action"];
[MainInterfaceController openParentApplication:dictionary reply:^(NSDictionary *replyInfo, NSError *error) {
NSLog(#"Reply received by Watch app: %#", replyInfo); // the reply from the appDelegate...
}
in your parent's app Delegate :
- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
NSLog(#"Request received by iOS app");
if( [userInfo objectForKey:#"action"] isEqualToString:#"getSomething"] ){
//call you're Web API
//send the reponse to you're glance :
reply(DictResponse);// some Dictionary from your web API...
}
*****EDIT*****
i've been issued the same issue, one easy fix is to begin an background task, from :
fiveminutewatchkit
Here's the way :
- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
// Temporary fix, I hope.
// --------------------
__block UIBackgroundTaskIdentifier bogusWorkaroundTask;
bogusWorkaroundTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{
[[UIApplication sharedApplication] endBackgroundTask:bogusWorkaroundTask];
}];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[[UIApplication sharedApplication] endBackgroundTask:bogusWorkaroundTask];
});
// --------------------
__block UIBackgroundTaskIdentifier realBackgroundTask;
realBackgroundTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{
reply(nil);
[[UIApplication sharedApplication] endBackgroundTask:realBackgroundTask];
}];
// Kick off a network request, heavy processing work, etc.
// Return any data you need to, obviously.
reply(nil);
[[UIApplication sharedApplication] endBackgroundTask:realBackgroundTask];
}
in fact iOS kill your parent's app before you can retrieve data... this (not very clean solution) prevent you're app to be killed... and let you the time to retrieve infos...
