Annot render problem on device

Hi,

I set the break point and check the value of
[m_doc canSave] , returns 0 every time with any documents. Even with the help.pdf file in demo code.

Even I checked the code on different machine and did not get the expected result.

Hi,
The help.pdf is a readonly file ,it can not modified.

Did you use iTunes move file to PDFViewer Document?
set break point at RDFileTableController line 133,check if path like
/var/mobile/Containers/Data/Application/874CE321-6B3A-4122-B068-65CBB12574D8/Documents/

If in this document,check if your device has writable authority, write a file write demo ,
use
fopen( sFile, "rb+" );
then write something to check.
