ios6

问题 I'm trying to implement the new social framework in iOS6, and have it working, except for 2 weird problems. If I've enabled the services I'm interested in (say... FaceBook), then it works fine.

问题 folks! I'm implementing a shared cache in my app. The idea is to get the cached data from the web in the background and then update the cache and the UI with the newly retrieved data.

问题 I am using Xcode 4.5 and using the base SDK, iOS6 and am porting my app for iPhone 5. Some of the libraries that I use for my app are still not built for armv7s architecture. Will removing support for armv7s architecture still work fine for the iPhone 5 screen? Or, will I see black letterboxes? It works fine on the simulator though. Would like to know if anyone got a chance to test this case. 回答1: Yes, it should work fine. The deciding factor for whether your code will letterbox is the
