Hi Rick,
Try looking at the NSString snippet on <URL:

I'm trying to remove excess line breaks from a string, replacing any
given number of returns with one single return. If I were doing it in
perl, it would look like this:
$theString =~ s/\r+/\r/g
So, here's what I come up with in Cocoa. If it looks a little
convoluted, well... it is. And it also doesn't work. Any thoughts with
what's wrong with this or possibly a more elegant way to do it would
be appreciated. The first line is just a test to see if the string
still contains any occurrence of a double return; the third line
simply runs through and replaces any double returns with a single
return.
if ( (NSEqualRanges ([endString rangeOfString:@"\r\r"],
NSMakeRange(NSNotFound, 0) ) ) == NO)
{
[endString replaceOccurrencesOfString:@"\r\r" withString:@"\r"
options:nil range:NSMakeRange(0, [endString length])];
}
Love,
Jens
