NSInternalInconsistencyException with 'CGPDFDocumentRef == NULL'

Question

I am building a Newsstand universal app. When I download a magazine issue and open it, it runs fine, but when I delete it, redownload, and open it it throws the following:

2013-04-01 22:06:07.672 Magazine[14353:707] *** Assertion failure in -[ReaderContentPage initWithURL:page:password:], /Volumes/Files/Work in progress/el-beit/Magazine/Sources/ReaderContentPage.m:471
2013-04-01 22:06:07.680 Magazine[14353:707] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'CGPDFDocumentRef == NULL'
*** First throw call stack:

terminate called throwing an exception(lldb)

I delete the file by deleting its issue:

NKLibrary *nkLib = [NKLibrary sharedLibrary];
NKIssue *issue = [nkLib issueWithName:[kBaseFeatureID stringByAppendingString:((NSNumber *)self.listOfMonths[index]).stringValue]];
NSString *name = issue.name;
[nkLib removeIssue:issue];
[nkLib addIssueWithName:name date:[self.dateFormatter dateFromString:((NSNumber *)self.listOfMonths[index]).stringValue]];

I am using Newsstand, iOS6, Xcode 4.6, MKStoreKit, and the template of this project: https://github.com/vfr/Reader

The reader seems to be trying to open the deleted file instead of the file I give to it.

Any help would be appreciated, thanks in advance.

I solved this issue by using

[[ReaderDocument alloc] initWithFilePath:file password:nil];

instead of

[ReaderDocument withDocumentFilePath:file password:nil];

I think that this post could solve your problem.

I get the same error, but from a different Workflow. If I download a file and save it to the filesystem the error appears, but if I add the same file to my AppBundle it gets displayed without any problem.

I hope that this helps, eventually you have any advice whats wrong at my case. I suggest that this is because of the same reason.

The plist file was the problem, it didn't get deleted automatically when you deleted your PDF. You have to either make sure all your PDF file names are unique, or remember to delete the plist file which is automatically generated by the Reader based on PDF file name.

E.g. /appid/Library/Application Support/yourPdfFileName.plist

Do it every time when you delete your PDF. It should solve your problem.
