i'm having a problem comparing some type of strings, for example the
one giving me a problem right now.
is let's say in my database i have 4 version of the same string .
"sandro's computer"
"sandro's_computer"
"sandros computer"
"sandros_computer"
I would like them to compare as being equal,
is there a way I can mingle with the comparing routine
to ask it to ignore some characters in the comparison?
First strip out the characters to be ignored:
NSString* tempString = [myString stringByTrimmingCharactersInSet:
[NSCharacterSet characterSetWithCharactersInString:@"'_ "]];
returns "sandroscomputer" given any of the above.
Are you quite sure?
The Tiger documentation says: "Returns a new string made by removing
from both ends of the receiver characters contained in a given
character set."
If this is still true, then the internal apostrophs would not get
removed.
But maybe I am misunderstanding the documentation.
DId not actually test this.
Kind regards,
Gerriet.
