问题 Can I use storyboards for all of my app, and then have one nib that it pushes to, or is the two being used at the same time not possible? 回答1: The storyboards and nibs can go together in one app, but if your deployment target is below iOS 5, then it won't work. The storyboards will only work on iOS 5.x. And of course, you'd need to write code yourself to push a nib. 回答2: WWDC 2011 Videos Session 309 - Introducing Interface Builder Storyboarding 36:00 API 41:00 Adoption (including incremental

问题 I've recently upgraded my Mac to Lion, and also Xcode 4. In Build Settings, I've set "Code Signing" for "Release" to be "iPhone Distribution" which matches our Ad-Hoc provisioning file (which we've used in the past, on Snow Leopard/Xcode 3). I have deleted the old Entitlements file (as it's apparently no longer used by Xcode 4). In the Scheme section, I've set Archive to use the Release build. I'm building with Product > Archive. I'm saving the file by going into the Organiser and clicking

问题 does an entry in Instruments "leaked block" during application running imply memory leak? That is, if one is half way through using the iPhone application, where you might have some variables that have been retained but it hasn't got to the part of the application where it gets released, then do these show up as leaked blocks or not? If the answer is that variables which have not been finished with do show up here as leaked blocks, then this would be quite confusing then if you are stopping

问题 I have a framework that's part of my app and I want to add it as a private framework so I can distribute it. However, I couldn't find a way how to do it.

Thanks. 回答1: Apple already provided steps for Embedding a Private Framework in Your Application Bundle. You should read this document. 来源： https://stackoverflow.com

The build continues to fail stating that it cannot find 'curl/curl.h' Am I not adding my search paths correctly? Thanks 回答1: User Header Search Paths - searched for
