I'm having a problem on how to tie the UISearchController at top of my UITableHeaderView. I've tried some scenarios I found here on the forum but they didn't work. It's scrolling, and I hate it. However when is active, it stays on the top. But I'd like to be on the top when is also inactive. Share some code if you have bros.
Instead of putting your UISearchController into a UITableHeaderView (which is why it's scrolling along with the table cells), add your search bar on top of the UITableView.
And if you're using a UITableViewController, please ditch that (because it doesn't play nice with views added on top of the table) and use a custom UIViewController with a table view as a subview inside of the content view.

I'm using a TableViewController and I've added my own navigation bar on top to match the other tabBar pages that I have.
I had to place at the top an empty view to lower the starting point of the table view so it wouldn't cover my navBar, which was already annoying.
Now it looks fine except that when I scroll up my list both navBar and TableView go under the status bar.
I want my navBar to stay where it is and the TableView not to go under the status bar when scrolling.
For starting I can't add any other stuff in my scene if not under the table view and i get that that's causing the nav bar to follow the tableview up so that's part of the problem..

When creating this kind of structure (table + other elements), the best approach is to actually have a ViewController that contains a TableView and additional elements (like your navigation). Do not try to put elements, that are not part of the table itself inside the table.
Here is an example of the structure, where I have intentionally coloured the custom view (in your case the navigation) orange. As you can see, it is outside the table. This way the showing and scrolling of the table is completely separated from the other elements.
you can try self.edgesForExtendedLayout = UIExtendedEdgeNone;
I have simple chat application with text messages view-based NSTableView as you can see at the picture below.
Each message contains NSTextView instance having height to fit all the text.
All I need is to start NSScrollView (which NSTableView-instance is enclosed by) autoscrolling while the user selecting text dragging mouse far enough. Unfortunately, autoscrolling doesn't appear. In case of dragging somewhere outside of the text views all succeed.
I tried to call autoscroll:-method directly by simply push NSEvent-instance from NSTextView-subclass "mouse dragged"-event (like in example from this article):
- (void)mouseDragged:(NSEvent *)event
{
[self.scrollView autoscroll:event];
}
As I've overrode all the mouse events and implemented all the text selecting, this method often invokes. But the autoscrolling doesn't seem to work.
UPDATE
I figured out that before calling -autoscroll:-method there must be -mouseDown: of the same object. But it breaks my text selecting mechanism. The point even not in being first responder, there must be nothing but the mouseDown:-method.
Normally, a text view is within a scroll view of its own. Even if that's big enough to show all of the text without scrolling, it's still there. A call of -autoscroll: on anything within that scroll view (possibly including that scroll view itself?) will just try to scroll that scroll view, not the scroll view that contains the table view.
Try calling -autoscroll: on a view higher up in the hierarchy. Either self.scrollView.superview, the table cell view, or the table view.
Note, though, that the table view's scroll view will keep scrolling even after the cell view containing the text view is fully on-screen. In fact, it may keep scrolling it so far that it's off the screen in the other direction. Basically, it doesn't know that you're trying to select within the text view so it doesn't know to stop when the selection extends all the way to the edge of the text view.
Another approach might be to try to use a "bare" text view with no enclosing scroll view. I don't think IB will let you do that, so you'd have to do it programmatically. Bare text views don't play well with auto layout, though.
This is hard to explain but i'll try my best. I have a Table View controller that leads to 10 View controller. All the View controllers have a navigation bar title (The titles are the 10 objects from the Table view controller). Now i want to add the Swipe Gesture for a easier navigation between the 10 table view items (Instead of going back to the Table view manually i want the user to be able to swipe to change from a view controller to another). HERE'S THE PROBLEM: When i add the Swipe Gesture and i connect it from one view to another, it asks if i want the action to be either: Push, Modal or custom. Now, if i choose one of them, it makes the navigation bar title disappear. I want to keep the title without messing up the connection from the table view to the views controller. Thanks.
You want a pageviewcontroller. Set up the pages to be your different view controllers
A pageviewcontroller essentially allows you to do exactly what you want to do without having to setup a new segue every single time. That way it can all happen under one navigation bar. If you've seen the twitter app, you know how you can scroll through your feeds? Same thing.
There are tons of tutorials on the web, but pageviewcontroller a can be a tiny bit tricky because they require some logic
Here's a slightly more advanced thing that might be useful to you:

I have a reasonably complicated UIView which contains several nested views which are displayed according to a variety of responses - all are laid out in a storyboard.
Is there a way to hide a view in the foreground to work on a view in the background? As its really fiddly selecting particular elements to arrange / style!?
I've been trying to figure out a nice way to do this, some function like hiding the view and its subviews from the storyboard (not from the actual application), but couldn't find anything.
This is not the nicest of ways but it is how I do it at the moment...
What I do is select the views I want to "hide" from the document outline and add a constant (screen width/height) value to its x/y origin value to push them out of the screen. I also change the document label for those views (Identity Inspector > Document > Label) to something like "Hidden" so I can later search for the "hidden" views from the document outline and put them back where they belong.
I have 2 work arounds.
A) Change the View Controllers size to freeform. Set its size to be really large so I can space out the views.
B) Use the sort order of the views Document Outline (lowest is front most) and add an image view (same as the view background) under the first view to block the others. Then delete it after finishing my edits.
or xcode developers could just simple add a design-visible checkbox for views and controls.... but ill take my rants somewhere else.
In xcode 7 you can do it from the storybord

Maybe this could help you :
Open your storyboard in the Finder and edit it with a simple text editor (not xcode).
You will see it's just a xml file.Look for the view you want to hide, and add hidden="YES" in the parameters list.
That's what I do on my own project.
In Xcode when you select your storyboard, you have a panel that displays all your view controllers and their hierarchy. If you change the order of the elements you change the background/foreground order.
You can add extra views to the scene dock.
These views get initiated along with the view controller, but are not added to the view controller's view hierarchy. You can reference them using IBOutlets.
e.g. I have a full screen loading view that I added to the scene dock instead of covering up the view controller in the storyboard. I can add the loading view to the view controller's view hierarchy in code:
#IBOutlet weak var loadingView: UIView!
...
loadingView.frame = view.bounds
loadingView.autoresizingMask = UIViewAutoresizing.FlexibleWidth.union(UIViewAutoresizing.FlexibleHeight)
view.addSubview(loadingView)

Can anyone please tell me how to fix the following issue.
I am building an iPhone app using Storyboard. I have a Navigation Controller as root view and off that a view controller. On this I have a few buttons that when clicked takes you to a table view controller. All fine and well, but when I link the buttons to their respective table views, the top navigation bar obscures the top cell in the table view controller.
Does anyone know why this is happening and how I can fix it?
Also it seems to have thrown off my layouts from the view controller from which they inherit.
See attached image for a better explanation perhaps.
I believe this is the intended behavior when using the translucent navigation bar. It's semi transparent specifically so that you can see items pass behind it (e.g. a table scrolling). If you don't want this, changing the navigation bar's style to opaque should solve the problem.
Since I wanted to keep the translucence, I just added a UIView between the navigation controller and the prototype cell (width of the view, height 60). That way the first cell in the table starts beneath the navigation bar but I can still see the scrolling underneath.
This is a bug/feature in IB when you use a translucent navigation bar, the content view runs under the navigation bar. For non transparent bars the content view begins after the bar. If your content view is a UIScrollView (UITableView is a descendent of UIScrollView) the content will be automatically scrolled so as to not be hidden under the navigation bar. So the problem only exist in IB when you run the app everything should be ok.
You just need go to the Navigation Controller properties, then Simulated Metrics, and change the Top Bar to be a Transluscent Navigation Bar WITH PROMPT. And that should be it. No need for that extra UIView
