What happen if I return false in didFinishLaunchingWithOptions?

Question

I tried to return the false in didFinishLaunchingWithOptions method, nothing happens my app run successfully, can anyone tell why this thing work, and what's the difference (true/false) here.

Answer 1

It doesn't determine if the app launches or not, just whether it can handle the "option" or not.

Return Value

false if the app cannot handle the URL resource or continue a user activity, otherwise return true. The return value is ignored if the app is launched as a result of a remote notification.
