问题 I use the signpass form the Apple passbook demo passbook_materials to create a .pkpass file I have created my pass type ID and change the passTypeIdentity in the pass.json. When I execute: ./signapss -p ./myPass in terminal, it shows: Couldn't find an identity for pass.com.xxx.xxx. Does someone know this? 回答1: You need to install your certificate into your keychain (double clicking on the file downloaded from Apple will suffice). You need the Apple WWDR certificate installed in your keychain

问题 My app was working just fine until I updated to Xcode 4.5 and I ran it on IOS 6. Now it crashes with the exception - UIViewControllerHierarchyInconsistency - A view can only be associated with at most one view controller at a time. Does any one have an idea why and how can I solve it? 回答1: Well I fixed that problem - Apparently you need to remove the UIViewController in the XIB file, and leave only the view. 来源： https://stackoverflow.com/questions/12641833/app-crashes-on-ios-6

问题 I have two apps I'm developing at the moment, App1 , which is downloading files from Dropbox to the iPad, and App2 . The Dropbox integration is a bit of a hassle, and I'd rather not do it on both apps. So is it possible to save those files from App1 somewhere that App2 might access them? I've heard that the Sandboxing of apps got a bit looser in iOS6, but not really sure how loose. I've seen some similar questions here, but they seem to be solved by using URL schemes or sending data to the

问题 How to read error codes which appear in the console? <Warning>: ....... -exited abnormally with signal 9: Killed: 9 <Warning>: ....... -1 err = Bad file descriptor (0x00000009) Here what does signal 9 mean, are there any more signals apart from it.

问题 First, I have tried every answer for the question - application executable is missing a required architecture armv6 This worked last week before I downloaded iOS 6. Now I am getting the following error when validating my archive for distribution. To my knowledge, the only change is iOS 6. So I believe there must be a new step I'm missing. 回答1: XCode 4.5 no longer supports armv6 compilation.
