Any help will be appreciated.

Choice - 1

NSString *final=@"(IN)+91";
NSArray *tempArray = [final componentsSeparatedByString:@")"];
final = [tempArray lastObject];
NSLog(@"%@", final);

Choice - 2

NSRange range1 = [final rangeOfString:@")" options: NSBackwardsSearch];
NSString *newString = [final substringFromIndex:(range1.location+1)];
NSLog(@"%@",newString);

Use this,

    NSString *myString = @"(IN)+91";
    NSArray *subStrings = [myString componentsSeparatedByString:@")"];
    NSString *firstString = [subStrings objectAtIndex:0];
    NSString *lastString = [subStrings objectAtIndex:1];
    NSLog(@"first - %@, second - %@", firstString, lastString);

Use Regex to replace all matched text at once

NSError *error;
NSString *pattern = @"\([^\)]*\)";
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:pattern options:NSRegularExpressionCaseInsensitive error:&error];
NSString *afterText = [regex stringByReplacingMatchesInString:beforeText options:0 range:range withTemplate:@""];
