For Loops, i and Strings Troubles in Objective C

I'm trying to append a string with a number and I'm using a for loop to do it. For some reason though I'm getting the error "Expected identifier."

How do I get rid of this issue in objective C? 

  for (int i=0; i<10000; i++)
{
    int num = 0;
    num = num + i;
NSString *current = [@"/current%d.html", num];

NSString *filePath = [basePath stringByAppendingString:current];
 //   NSLog(@"current");

Here's a snippet of my code where I'm getting the error.

Try changing [@"/current%d.html", num]; to

[NSString stringWithFormat:@"/current%d.html", num];

When you enclose your statement in [], Obj-C expects the statement to be a message-receiver pair. Here the +(NSString *)stringWithFormat:(NSString *) class method receives the NSSting @"/current%d.html", num" message/parameter.

Don't know all the proper terminology, but thats the get of it I believe.

And as Josue pointed out, num will be the same as i in your code. Perhaps you meant to initialize before the for loop?
