CGPDFDocumentRef from NSData
You can create a PDF document using this function:
CGPDFDocumentRef CGPDFDocumentCreateWithProvider ( CGDataProviderRef provider);To create the provider you can use this function:
CGDataProviderRef CGDataProviderCreateWithCFData ( CFDataRef data);and consider that NSData and CFDataRef are toll-free bridged so you can use them interchangeably.
So summarizing try this:
NSData *data = ... my data from SQLite ...CFDataRef myPDFData = (CFDataRef)data;CGDataProviderRef provider = CGDataProviderCreateWithCFData(myPDFData);CGPDFDocumentRef pdf = CGPDFDocumentCreateWithProvider(provider);Don't forget to CFRelease all unused data.
