We use NSSet KVO instead of array KVO for this exact reason. Another
option is to cache the array

Hi Jack,
Thank you for your quick response. Your answer is very useful.
Since I have pasted some of my codes in the previous mail. I just
wonder if you have any comments on my codes, anything I can
improve for this little app? Any advice will be very appreciated.

You can use the CGPDF API. However be careful on memory usage (in particular
keeping the CGPDFDocument open all the time could lead to some memory issues
that could be workarounded by closing and reopening it)

UIWebView is the easiest way to view PDFs. But if you want any editing or other
custom manipulation, will need to drop down lower to CoreGraphics.

Hi Gustavo,
When you draw a CGPDFPageRef into a graphic context, Quartz will hold images
inside the PDF page in a sort of cache (at least, it seems with Instrument
Object Alloc). You can only empty that cache by destroying the
CGPDFDocumentRef.
However, if you do not destroy your CGPDFDocumen
Rafael hi
Thanks for the info,, I will be testing the behavior with some pdfs and see
whats better, to keep the CGPDFDocumentRef and destroy it when closing the

I am interested in simulating text input (maybe via generating keystrokes), but

One example is redirecting input from a serial port to the active application.

Well VNC must simulate keystrokes somewhere along the line, although finding it

Static variables inside member functions are initialized only once, static
variables therefore keep the state of the variable in repeated calls.
