Question

i have one NSString object , for ex:- ($45,0000)

Now i want to find if this string contains () or not

How can i do this?

Answer 1

Are you trying to find if it contains at least one of ( or )? You can use -rangeOfCharacterFromSet::

NSCharacterSet *cset = [NSCharacterSet characterSetWithCharactersInString:@"()"];
NSRange range = [mystr rangeOfCharacterFromSet:cset];
if (range.location == NSNotFound) {
    // no ( or ) in the string
} else {
    // ( or ) are present
}
