The problem is that the text field is way too slow in updating its
value. So slow infact that nothing appears on the text field until
all the files have been copied.
Any faster way to do this?
As Kyle has already mentioned, you're asking the same question as in
your NSProgressIndicator thread.
Have you thought of changing your code so that your file processing
is done in a worker thread? Then you could call -
performSelectorOnMainThread:withObject:waitUntilDone: just before
processing each file. If you set wait=NO then the UI can update
itself without having to jump through hoops and the file processing
can run without having to wait for the update to occur.
