And I've also maken sure that NSURLConnection doesn't download new data work while app goes background. Then how's it possible with Kindle app? Edit: I haven't checked Kindle App in iOS4

问题 In iOS 9, is it possible to detect when an app is running in iOS 9's Slide Over or Split View mode?

Does using Tasks (TPL) library make an application multithreaded?

由 五迷三道 提交于 2019-11-26 17:10:25
Recently when being interviewed, I got this question. Q: Have you written multithreaded applications? A: Yes Q: Care to explain more?

Tasks can be used to represent operations taking place on multiple threads, but they don't have to.

问题 I have a method which does 2 independent pieces of logic. I was hoping I can run them both at the same time .. and only continue afterwards when both those child methods have completed. I was trying to get my head around the async/await syntax but I just don't get it. Here's the code: public PewPew SomeMethod(Foo foo) { var cats = GetAllTheCats(foo); var food = GetAllTheFood(foo); return new PewPew { Cats = cats, Food = food }; } private IList<Cat> GetAllTheCats(Foo foo) { // Do stuff, like

I have the UIApplicationDelegate protocol in my main AppDelegate.m class, with the applicationDidBecomeActive method defined. I want to call a method when the application returns from the background, but the method is in another view controller.
