self.tableView.tableHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.tableView.bounds.size.width, 0.01f)];
I like this solution better than setting a somewhat arbitrary contentInset.top because I use the contentInset.top dynamically as well. ...

In particular, this allows vector to only do one allocation (since it can't determine the distance of set iterators in O(1)), and, if it wasn't defined for vector to zero out each element when constructed, this could be worthwhile to allow the copy to boil down to a memcpy...

Difference between null and empty (“”) Java String
... String("");
System.out.println(a==b);
That would output false because I allocated two different objects, and a and b point to different objects.
