maybe convert your search string to an NSMutableString and then use:
replaceOccurrencesOfString:withString:options:range:
for example:
NSMutableString search = [NSMutableString stringWithString:
searchterm];
[search replaceOccurrencesOfString: @"%"
withString: @"\%"
options: NSLiteralSearch
range: NSMakeRange(0, [search length])];
