Grouped UITableView 35 point / pixel top inset / padding

Question

Please note, I'm going to refer to points as pixels in this question.

I have a grouped UITableView with 3 sections, each with a 40 pixel tall header view. The first header in the table view seems to be given a y position of 35 pixels by the system.

I've tried messing around with automaticallyAdjustsScrollViewInsets and a few other iOS 7 automatic pieces, but to no avail.

Why is my UITableView content being inset by 35 pixels?

EDIT: I've seen this answer and many other threads on this. I have valid headers and header heights. Also, setting the default to FLT_MIN, 0.01f, 1.0f or 100.0f doesn't fix the problem.

Here is my header implementation:

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    UIView *header = (self.headerViews.count > section ? self.headerViews[section] : nil);
    return (header.viewHeight ? : FLT_MIN);
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *header = (self.headerViews.count > section ? self.headerViews[section] : nil);
    return (header.viewHeight ? header : nil);
}

I'm also setting:

- (BOOL)automaticallyAdjustsScrollViewInsets{return NO;}

and

[self setSectionHeaderHeight:FLT_MIN];

Answer 1

It seems that this:

[self setTableHeaderView:[[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, width, FLT_MIN)]];

In init, where self is a UITableView, will get rid of the top 35 points.
