Are you waiting for the NSTask operation to finish before reading
from the file handle?
NSTask *pdfTask = [[NSTask alloc] init];
NSString *pdfOutput;
[pdfTask setLaunchPath:@"/your/path/here"];
[pdfTask setStandardOutput:[NSPipe pipe]];
[pdfTask launch];
[pdfTask waitUntilExit]; // wait for the task to finish before
continuing!
pdfOutput = [[NSString alloc] initWithData:[[[pdfTask standardOutput]
fileHandleForReading] availableData] encoding:NSASCIIStringEncoding];
[pdfTask release];
// do stuff with pdfOutput and release

Hi
I am trying to send text to a perl script, I want to apply regular
expressions to the text, then I use the result.
I am using a pipe to send the text. I create the pipe, and the file
handle, and it works for small text strings.
When I try to pass the text from a 100 page PDF, it fails. Is there a
limit on the amount of data I send to a script, or am I just doing
something wrong?
Thanks,
Dave.
