tableView + height of subView changes suddenly

Question

Here is my code:

UIView * ivHeaderContainer = [[UIView alloc]init];
UIView * ivFooterContainer = [[UIView alloc]init];
UIImageView * ivHeader = [[UIImageView alloc]init];
UIImageView * ivFooter = [[UIImageView alloc]init];

PO1(self.tableHeaderView);
PO1(ivHeaderContainer);
self.tableHeaderView = ivHeaderContainer;
PO1(self.tableHeaderView);
PO1(ivHeaderContainer);
[ivHeaderContainer addSubview:ivHeader];
PO1(self.tableHeaderView);

Here is the log in console:

(41)> ivHeaderContainer: <UIView: 0x1a497700; frame = (0 0; 0 0); layer = <CALayer: 0x1a497760>>
2014-01-24 12:15:11.441 domainname[13727:40ab] <0x1a490220 Image+imageFile.m:(30)> [NSString stringWithString: self.fullFileName]: /private/var/mobile/Applications/BF1CCA03-2406-4FC9-BE33-298AD6DBAC2C/tmp/http%3A%2F%2Fimg.agoda.net%2Fhotelimages%2F475%2F4755%2F4755_08091300010092992_std.jpg.png
2014-01-24 12:37:32.767 [13727:60b] <0x165ff400 BGTableViewWithBackgroundAndTopAndBottom.m:(43)> self.tableHeaderView: <UIView: 0x1a497700; frame = (0 35; 320 0); layer = <CALayer:

So, after the line

self.tableHeaderView = ivHeaderContainer

the value of ivHeaderContainter is suddenly [0, 35, 320, 0] instead of [0, 0, 0, 0]. Don't know where the number 35 comes from.

Only happens on one xib. What could be the reason ?

Function PO1 (print object 1) simply print the stuff out.

This only happens when the table is grouped. But other grouped table doesn't have this issue.

What on earth does the function PO1 do? Zero chance of even guessing with method names like that... — occulus, Jan 24 '14 at 10:02
Right, and the take-away is to explain that in your post with a simple comment. — occulus, Jan 27 '14 at 14:37

I declared the future tableViewHeader with this

UIView * ivHeaderContainer = [[UIView alloc]initWithFrame:CGRectMake(0,0,.01,.01)];

Instead of

UIView * ivHeaderContainer = [[UIView alloc]init];

Problem is magically solved. It follows solutions here: Why is there extra padding at the top of my UITableView with style UITableViewStyleGrouped in iOS7

Next question. Why?

There's no such thing as "next question" in an answer to a question on Stackoverflow. Maybe edit your original question? – occulus Jan 27 '14 at 14:38
I am saying that this answer leads to another natural question. – user4951 Jan 28 '14 at 10:41
