My App does some background fetching, and during the fetch I would like to invoke a function that is located in one of my viewControllers What is the correct way to use the completionHandler , I'm aware that it is an asynchronous task.

由 血红的双手。 提交于 2019-12-07 02:15:37
问题 According to the iOS Developer Library The app delegate is where you write your custom app-level code. Like all classes, the AppDelegate class is defined in two source code files in your app: in the interface file, AppDelegate.h, and in the implementation file, AppDelegate.m.
