Reversing a String (Gabe Shahbazian)

[Peter Hudson]

I have been using the following for a while across a number of  
languages without problems.

NSString *s = @"Hello";
unsigned int length  = [s  length];
unsigned int index = length - 1;
        
NSMutableArray *ma = [NSMutableArray  array];
        
while( index < UINT_MAX )
{
        NSRange rng = NSMakeRange( index, 1 );
        [ma  addObject:[s  substringWithRange:rng]];
        --index;
}
        
NSString *reversed = [ma  componentsJoinedByString:@""];
NSLog(@"reversed : %@",reversed);
