Thanks for your advice Douglas. Unfortunately, as it's my first encounter
with those functions I got everything wrong again. Just to gain familiarity
with the -getLineStart:end:contentsEnd:forRange, I tried the following
fantasy
code :
unsigned* startIndex=47;
unsigned* lineEndIndex=48;
unsigned* contentsEndIndex=49;
unsigned i;
for (i=0;i<l1;i++) {
[z1 getLineStart:startIndex
end:lineEndIndex
contentsEnd:contentsEndIndex
forRange: NSMakeRange(i,1)];
}
(z1 is an NSString whose length is large,>50).
The loop crashes immediately (when i=0). What is wrong with
this code ? (in my mind it was supposed to compute for each i
the index of the line containing the ith character).
