When I scroll my TableView, it scrolls over my navigation bar (which I made without using the built in navigation bar for various reasons). See below:

Scrolled up:
How do I make it so that the TableView scrolls under the Navbar?
SOLVED:
I checked the "clips subviews" box for the table view to fix this problem.
To me, it looks like there may be an issue with your view hierarchy. Now, I assume that you built your own navigation bar by subclassing UINavigationBar.
In order to get the kind of behavior you need, you should have the following:
UIWindow's rootViewController is an instance of UINavigationController.
UINavigationController.navigationBar = your subclass of UINavigationBar.
UINavigationController.viewControllers[0] = UITableViewController
The UITableViewController.view = your UITableView

I have a UIViewController that contains a UICollectionView pinned to all edges of the view. This view controller is inside a UINavigationController.
I want to gradually hide the navigation bar as I scroll down in the collection view. At the point that I have scrolled the distance of the height of the nav bar, the nav bar should be completely hidden. If I scroll back up it should gradually show the nav bar.
I have tried all the open source navigation bars on github, but none of them work correctly with iOS 12.
How can I achieve this?
UICollectionView is a subclass of UIScrollView and therefore you have access to its scrollViewDidScroll delegate method. Your UIViewController is also owned by its navigation controller, so you can create an instance property in the view controller, like navigationDelegate: UINavigationController?, that will act as a delegate. In the navigation controller, set that property equal to self and manipulate the nav bar however you want through the scroll delegate. Absolutely no need for third-party scripting for something this standard and basic.
I have a custom UIContainerView. Inside the UIContainerView is a Controller with a UITableView. The TabBar keeps covering the last cell of my TableView. How do I prevent that from happening? I already tried the suggestions at TableView Showing Behind Tab Bar and Tab Bar covers TableView cells in iOS7 and Tab bar covers UITableView's last cell at all levels: in the VC holding my container view and in the VC of the TableView, as appropriate. I am not having much success. I set the constraints, I remove constraints — still nothing. Help!
I am using iOS7 and Xcode5.
I have a View Controller with UITableView declared in storyboard. The View Controllers has "Under top bars" option selected (Edge Rect). Normally the view looks like the below image.
There is no gap between the cells of the tableview and navigation bar.
The filter in the right bar button item presents filter view controller modally and
when returning back (dismiss), there is content inset (additional) added (by I don't know who). The final looks like this.
I have tried to set content inset in viewWillAppear, viewDidLayoutSUbviews etc. But nothing seems to work. Has anyone ever come across similar kind of problems? How can I remove this contentInset.
I am using Storyboards, and am interested in inserting a UISegmentedControl in my UITableView controller as such:
When I try to drag one directly from the object list, I can't manage to insert on top of the tableView above the search bar and below the nav bar. I also didn't have any luck dragging it into the view hierarchy panel on the left. I have looked into doing it programmatically as suggested by this SO answer, but do not want the segmented control to be inside the Nav Bar, but rather still in the tableView. How may I go about doing this?
Thanks!
In the XIB, you need to have an underlying UIView with the UISegcontrol, the search bar, and tableviews as subviews.
I don't know why UITableView has bottom inset automatically despite I make UITabBarController be hidden by calling [setHidden:YES] before.
The view controller who has UITableView is a child of UITabBarController. I already know that automaticallyAdjustsScrollViewInsets helps any UIScrollView get proper 'contentInset' depending on status of it's container view controller.
So, I expected that UITableView's bottom contentInset will be 0 if UITabBar is hidden. But, doesn't do that.
Although automaticallyAdjustsScrollViewInsets is YES, should I manually adjust that value when UITabBar is hidden?
Tab bars have never been meant to be hidden - after all why have a UITabBarController if you want to hide the tab bar. In the documentation, you are warned not to modify the tab bar object directly:
You should never attempt to manipulate the UITabBar object itself
stored in this property.
This is exactly what you are doing when setting it to hidden.
In iOS6 this has worked, but now in iOS7, it doesn't. And it seems very error prone to hide it. When you finally manage to hide it, if the app goes to the background and returns, Apple's layout logic overrides your changes. There are many such triggers.
My suggestion is to change your design. Perhaps display the data modally.
Putting this here for anyone who gets this problem for nested view controllers.
My view controller containment hierarchy is:
UINavigationController
|--UIViewController
|--UITabBarController
|--UIViewController
The last view controller has a UITableView whose scrollIndicatorInsets keep getting offset by the tab bar controller's UITabBar height even if it is hidden.
Solution: Set automaticallyAdjustsScrollViewInsets to false in the view controller that contains the tab bar controller (and is inside the UINavigationController). No need to set additional properties in the tab bar controller itself and the second view controller where the UITableView is.
