Set UITableView content inset permanently

Question

In my app I have a UISearchBar under UINavigationBar so it is always visible to user. In that case I had to set contentInset with extra 44px so the UIScrollView will be scrolling under UISearchBar (exactly like in Contacts.app). And there would be no problem with static UITableView's but in my case I have to reload it's contents, switch to UISearchDisplayControlleretc. So when I call:

[self.tableView setContentInset:UIEdgeInsetsMake(108, 0, 0, 0)];

Everything works until e.g. I pull to refresh... (for this I use SSPullToRefresh).

So my question is: How can I set contentInset permanently so I wouldn't have to worry about any changes happening to data inside UITableView?

Probably it was some sort of my mistake because of me messing with autolayouts and storyboard but I found an answer.

You have to take care of this little guy in View Controller's Attribute Inspector asvi

It must be unchecked so the default contentInset wouldn't be set after any change. After that it is just adding one-liner to viewDidLoad:

[self.tableView setContentInset:UIEdgeInsetsMake(108, 0, 0, 0)]; // 108 is only example

iOS 11, Xcode 9 update

Looks like the previous solution is no longer a correct one if it comes to iOS 11 and Xcode 9. automaticallyAdjustsScrollViewInsets has been deprecated and right now to achieve similar effect you have to go to Size Inspector where you can find this:
Also, you can achieve the same in code:

if #available(iOS 11.0, *) {
    scrollView.contentInsetAdjustmentBehavior = .never
} else {
    automaticallyAdjustsScrollViewInsets = false
}

Genius! I think this "little guy" should be unchecked by default. Now what are in the storyboard (uitableview&uiscrollview) match what I have in my iPhone. – coolcool1994 Jun 26 '14 at 19:26

This has been bugging me for months, but not enough to look it up. Thanks – VaporwareWolf Apr 01 '15 at 00:00
Thank you! When "little guy" is checked, SB toys with contentInsets at viewDidLayoutSubviews (between viewWillAppear and viewDidAppear). – ObjectiveTC Mar 25 '16 at 01:09
What is equivalent in Swift 2.3? – Jayprakash Dubey Oct 18 '16 at 07:22
@JayprakashDubey shouldn't be much difference... `self.tableView.contentInset = UIEdgeInsetsMake(108, 0, 0, 0)` – cojoj Oct 18 '16 at 13:03
what does "this little guy" refer to? EDITED:Adjust Scroll View Insets. I had to download the image to see that – William GP Jan 13 '17 at 09:55

@WilliamGP it's "Adjust Scroll View Insets" chexkmark in Attributes Inspector – cojoj Jan 13 '17 at 09:57
It was enough to set `automaticallyAdjustsScrollViewInsets` to `.never` - no need to change the "Adjust Scroll View Insets". – Dmitry Dec 09 '19 at 23:50

In Swift:

override func viewDidLayoutSubviews() {
      super.viewDidLayoutSubviews()
      self.tableView.contentInset = UIEdgeInsets(top: 108, left: 0, bottom: 0, right: 0)
}

Why not calling `super.viewDidLayoutSubviews()` ? – Alexander Perechnev Feb 10 '16 at 12:59

There is no need for it because the default implementation of viewDidLayoutSubviews does nothing. (Source: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIViewController_Class/#//apple_ref/occ/instm/UIViewController/viewDidLayoutSubviews ) – rmooney Feb 10 '16 at 18:06

That's true Johanneke. It is best practice to call super, in case of architecture changes in your own application or changes to UIKit by Apple. – rmooney Apr 18 '16 at 16:32

automaticallyAdjustsScrollViewInsets is deprecated in iOS11 (and the accepted solution no longer works). use:

if #available(iOS 11.0, *) {
    scrollView.contentInsetAdjustmentBehavior = .never
} else {
    automaticallyAdjustsScrollViewInsets = false
}

It would be nice to be able to tie contentInsets to selected safe area (ie not all) – Jonny Nov 02 '17 at 08:41

Add in numberOfRowsInSection your code [self.tableView setContentInset:UIEdgeInsetsMake(108, 0, 0, 0)];. So you will set your contentInset always you reload data in your table

This doesn't work. When I pull to refresh content inset is being restored to factory settings. – cojoj Feb 25 '14 at 17:05

Maybe try moving that line to `viewDidLayoutSubviews`. – Corey Feb 25 '14 at 17:07
You can add your searchbar as header of your table too like this `[tableView setTableHeaderView:yourSearchBar];` – Fran Martin Feb 25 '14 at 17:11
But the search bar must be always visible to user. Nevermind, I've found solution. Read my answer. – cojoj Feb 25 '14 at 17:50

This is how it can be fixed easily through Storyboard (iOS 11 and Xcode 9.1):

Select Table View > Size Inspector > Content Insets: Never

After one hour of tests the only way that works 100% is this one:

-(void)hideSearchBar
{
    if([self.tableSearchBar.text length]<=0 && !self.tableSearchBar.isFirstResponder)
    {
        self.tableView.contentOffset = CGPointMake(0, self.tableSearchBar.bounds.size.height);
        self.edgesForExtendedLayout = UIRectEdgeBottom;
    }
}

-(void)viewDidLayoutSubviews
{
    [self hideSearchBar];
}

with this approach you can always hide the search bar if is empty

Try setting tableFooterView tableView.tableFooterView = UIView(frame: CGRect(x: 0, y: 0, width: 0, height: CGFloat.leastNonzeroMagnitude))

      self.rx.viewDidAppearOnce
            .flatMapLatest { _ in RxKeyboard.instance.isHidden }
            .bind(onNext: { [unowned self] isHidden in
