ios - Button Does Not Segue on First Click -


i have view controller segues multiple other view controllers. 1 of segues clicking on collection view cell , add button, both work perfectly.

however added uibarbutton item segues view controller , have created segue in main.storyboard instead of programmatically, issue when run app on phone, button not respond, if click on collection view cell segue works fine , when go using navigation bar button , press on uibarbutton segues when pressed fine.

why this, why segue when segue occurred?

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
