For Example if my .a file Contents the following data,

4 5 6

I want the Output in the following way,

2,3

5,6

It's may help you!

NSString *str=@"1 2 3";
NSArray *split = [str componentsSeparatedByString:@" "];
NSString *replacevalue=@" ";
for(int i=1;i<[split count];i++)
   {
     if([replacevalue isEqualToString:@" "])
        replacevalue=[NSString stringWithFormat:@"%@",[split objectAtIndex:i]];
     else
        replacevalue=[NSString stringWithFormat:@"%@,%@",replacevalue,[split objectAtIndex:i]];
   }

NSLog(@"%@",replacevalue);
