Solution

  • This code will work for any number of any countries:

    NSString *string = @"India(IND) United States(US)";
NSInteger openParenthesLocation;
NSInteger closeParenthesLocation;
do {
    openParenthesLocation = [string rangeOfString:@"("].location;
    closeParenthesLocation = [string rangeOfString:@")"].location;
    if((openParenthesLocation == NSNotFound) || (closeParenthesLocation == NSNotFound)) break;
    string = [string stringByReplacingCharactersInRange:NSMakeRange(openParenthesLocation, closeParenthesLocation - openParenthesLocation + 1) withString:@""];
} while (openParenthesLocation < closeParenthesLocation);
