appdelegate

问题 So I started an iOS app with the single view template. I then added a navigation controller by dragging it into the storyboard. How do I references this from my app delegate? I tried ctrl-dragging it into my AppDelegate outlet-style but that obviously doesn't work. What do I do? Instantiate one and then assign it as rootview controller? By the end of this I'd like to use the AppDelegate to set the view to the top of the navigation controller. Thanks! 回答1: In IB you should select the

问题 Here's my problem. I have implemented push notification in my app and it works just fine.

But I can't seem to figure out how to capture this touch and then do something with it in the appDelegate. I have an NSLog in the

If step 2 is the case, I want to open MenuContainerViewController within the completion block without any UI hiccups. Here is the

问题 I am trying to perform unit testing in swift.

问题 First of all I know about this: How do I get a reference to the app delegate in Swift? Second, what I need to do is to access the appdelegate properties in the Swift side of a mixed app. Basically, 1- I have a project which is started as an Objective C project.
