Try as I can, and following directions in ftp://mail.tprd.info/help_iOS_1.7.pdf, PDFViewer keeps crashing on Document_openMem (and also on Document_open).

Relevant code fragment:

- (int)PDFOpenURL:(NSURL *)url withPassword:(NSString *)pwd
{
    [self PDFClose];
    PDF_ERR err = 0;
    const char *password = [pwd UTF8String];
    NSData *data = [[NSData alloc] initWithContentsOfURL:url];
    void *rawData = (void *)(data.bytes);
    int size = data.length;
    m_doc = Document_openMem(rawData, size, password, &err);
//...

All the data looks normal & correct.
Tried lots of variations (not that there’s much to change, it’s a pretty straightforward call).
It just keeps crashing on that call with EXC_BAD_ACCESS.

Thoughts? probably something petty, but I'm not seeing it and can't look past the call as it's in the PDFViewer library.

Same problem with

- (int)PDFOpen:(NSString *)path withPassword:(NSString *)pwd
{
[self PDFClose];
const char *cpath = [path UTF8String];
PDF_ERR err = 0;
const char *password = [pwd UTF8String];
m_doc = Document_open(cpath, password, &err);

Data is fine:

self	RDPDFViewController *	0xdebfd90	0x0debfd90
pwd	NSString *	nil	0x00000000
path	__NSCFString *	@"/Users/cd/Library/Application Support/iPhone Simulator/7.1/Applications/C64B6BF1-5C65-4C85-9AF2-6AEA295BC409/AppName.app/help.pdf"	0x0dee0ce0
cpath	const char *	"/Users/cd/Library/Application Support/iPhone Simulator/7.1/Applications/C64B6BF1-5C65-4C85-9AF2-6AEA295BC409/AppName.app/help.pdf"	0x0dee0ce9
err	PDF_ERR	err_ok	err_ok
password	const char *	NULL	0x00000000
m_doc	PDF_DOC	0x0	0x00000000

help.pdf exists at the indicated location.
Execution does not get past Document_open, suffering EXC_BAD_ACCESS.

[view vClose]; [doc close]; PDFDoc need PDFObjc.h and PDFObjc.m in your project.
