I am currently trying to put a UITableView
in a different location rather than at the top of my view controller. With this said, it is trying to add the header
I just found a solution for this.
In my case, i was using TabBarViewController, A just uncheck the option 'Adjust Scroll View Insets'. Issues goes away.

Do the cells of the UITableView
show on the empty space when you scroll down?
If so, then the problem might be the inset that is added to the UITableView
because of the Navigation controller you have in your view.
The inset is added to the table view in order for the content to be placed below the navigation bar when no scrolling has occurred. When the table is scrolled, the content scrolls and shows under a transparent navigation bar. This behavior is of course wanted only if the table view starts directly under the navigation bar, which is not the case here.
Another thing to note is that iOS adjusts the content inset only for the first view in the view hierarchy if it is UIScrollView
or it's descendant (e.g. UITableView
and UICollectionView
). If your view hierarchy includes multiple scroll views, automaticallyAdjustsScrollViewInsets
will make adjustments only to the first one.
Here's how to change this behavior:
a) Interface Builder
There's a property called "Adjust scroll view insets" in IB's attribute inspector (when a view controller is selected) which is on by default. Uncheck this option:

I'm not sure which Xcode version introduced this option (didn't spot it in the release notes), but it's at least available in version 5.1.1.
Edit: To avoid confusion, this was the third option mentioned in the comments
b) Programmatically
Add this to i.e. viewDidLoad
(credits to Slavco Petkovski's answer and Cris R's comment)
// Objective-C
self.automaticallyAdjustsScrollViewInsets = NO;
// Swift
self.automaticallyAdjustsScrollViewInsets = false
c) This might be relevant for old schoolers
You can either fix this by adding
tableView.contentInset = UIEdgeInsetsZero
//Swift 3 Change
tableView.contentInset = UIEdgeInsets.zero
Or if you are using IB and if the navigation bar is not transparent (can't tell from the screenshot)
There is may be pre-added UIRefreshControl
. I have this problem with code like this:
self.refreshControl = [[UIRefreshControl alloc] init];{
[self.refreshControl setAttributedTitle:[[NSAttributedString alloc]
initWithString:@"Your string"]];
[self.refreshControl addTarget:self
action:@selector(updateScreen)
forControlEvents:UIControlEventValueChanged];
}
As you see, I set self.refreshController
immediately after init
But, if you set refreshControl
after setup, then top-space don't interfere you.
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];{
[self.refreshControl setAttributedTitle:[[NSAttributedString alloc]
initWithString:@"Your String"]];
[self.refreshControl addTarget:self
action:@selector(updateScreen)
forControlEvents:UIControlEventValueChanged];
self.refreshControl = refreshControl;
}
set ViewController's Extended Edges in storyboard so that underTopBar
property is unchecked.
Xcode 8 bug…
Try this first if your Storyboard UITableView style is set to Plain.
Set the table's style to Grouped and then back to Plain. This removed the space in my app at the head of my UITableView.
check for
if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
[tableView setSeparatorInset:UIEdgeInsetsZero];
}
