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.

then compare the resulting temporary strings as normal.
