Question

I want to add spaces (” “) infront of a string (like white spaces). this is the length of the spaces

 int spaces_needed=((36-[[dicBusinessDetails objectForKey:@"ResturantName"] length]))/2;

What I want is to create a string like this

 NSString stringWithFormat:@"               %@",[dicBusinessDetails objectForKey:@"ResturantName"];

But the spaces should NOT be fixed as above, but variable length of int spaces_needed.

Actual reason for doing this is to center align a string in a receipt

You might like NSString‘s stringByPaddingToLength:withString:startingAtIndex

NSString *result = [NSString stringWithFormat:@"%@%@",
                             [@" " stringByPaddingToLength:spaces_needed withString:@" " startingAtIndex:0]
                             [dicBusinessDetails objectForKey:@"ResturantName"]];
