If you dont want to replace mac with mac hello, then you can do in this way

NSMutableString *string=[NSMutableString stringWithString:@"hi mac this is ios"];
NSRange range = [string rangeOfString:@"mac"];    
[string insertString:@" hello" atIndex:range.location+3];
NSLog(@"str=%@",string);

Output :

str=hi mac hello this is ios

NSString *str = @"Hi Mac this is";

if ([str rangeOfString:@"mac" options:NSCaseInsensitiveSearch].location != NSNotFound)
{
    int location = [str rangeOfString:@"mac" options:NSCaseInsensitiveSearch].location;

    NSMutableString *mstr = [[[NSMutableString alloc] initWithString:str] autorelease];
    NSString *strtemp = @"mac";

    [mstr replaceCharactersInRange:NSMakeRange(location, [strtemp length]) withString:[NSString stringWithFormat:@"%@ %@", strtemp, @"hello"]];

    NSLog(@"test  %@", mstr);
}

You can use :

string = [string stringByReplacingOccurrencesOfString:@"Mac" withString:@"Mac Hello"];
