Answer 1

A lot of the previous answers above are too hacky. They would break at anytime in the future if Apple decides to fix this unexpected behavior.

Root of the issue:

1. a UITableView doesn't like to have a header with a height of 0.0. If what's you're trying to do is to have a header with a height of 0, you can jump to the solution.

2. even if later you assign a non 0.0 height to your header, a UITableView doesn't like to be assigned a header with a height of 0.0 at first.

Solution:

Then, the most simple and reliable fix is to ensure that your header height is not 0 when you assign it to your table view.

Something like this would work:

// Replace UIView with whatever class you're using as your header below:
UIView *tableViewHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.tableView.bounds.size.width, CGFLOAT_MIN)];
self.tableView.tableHeaderView = tableViewHeaderView;

Something like this would lead to the issue at some point (typically, after a scroll):

// Replace UIView with whatever class you're using as your header below:
UIView *tableViewHeaderView = [[UIView alloc] initWithFrame:CGRectZero];
self.tableView.tableHeaderView = tableViewHeaderView;
