I want my ViewController to be shared by a tableView and a TextView, where the TextView would appear beneath the TableView. But the TableView insists on taking over the entire scene/screen. How do I set the height of the TableView in the storyboard so I can make room for my TextView? (Please notice that I am not asking for a footer, which is actually what I am trying to change from)
The problem is that you are using a UITableViewController, which means that you get a scene with a full-screen UITableView.
To avoid this, use a normal UIViewController scene and just insert the UITableView into the interface manually (and configure its delegate and dataSource to point to the view controller).
UITableViewController is just a convenience. It doesn't do anything for you that you can't do yourself with a normal UIViewController. And in your situation, it is an inconvenience instead of a convenience.
Add a container view to your ViewController and link to an "external" UITableView instead of the provided UIView that comes with it when your drop it into your storyboard.
Send data via the segue, get it back via a delegate.
This way you can freely design your View with very little headaches.

I have a UIViewController with a UITableView that is fed with data from the local database. When the user first launches the app (after installing) the table view is empty and I display a UIView in the middle of the table view that contains a UIImage, a UILabel and a UIButton (a call to action).
The first version of this view I built programmatically, which was no good to me because every time I tweaked something I had to build the app again. Then I switched to the storyboard but had to drag a UIView to the middle of my tableView. It is working now but I don't like the way it is, I can't edit my table view cells without having to move the UIView out of the table view.
I'd like to have a way to build this view entirely separated from my tableView (or even from my view controller in question) and then reference it in the viewDidLoad call of my view controller.
Unfortunately Xcode does not allow us to drag views directly to the storyboard so I'm pretty lost here.
Please tell me if I haven't been clear enough. I appreciate any help you could give me.
UPDATE: It'd be particularly awesome to me if I could also create a custom Swift class for this view of mine and reference it in the storyboard. And then in my viewDidLoad I could simply instantiate my custom view.
Thanks in advance.
Create a XIB file in which you can drag a view (without a view controller).
In your code you can load the XIB using NSBundle.mainBundle().loadNibNamed("MyXibName", owner:self, options:nil).
In the XIB file you can give the UIView a custom class (like you can do with view controllers in storyboard).
You then of course have to retrieve the view from the array returned by loadNibNamed and cast it to your custom class.
I'v never used UITableViewControllers or UICollectionViewControllers, because you can have the same functionality by using UIViewController with its root UIView, then adding UITableView in xib or storyboard and assigning its delegate and datasource. And I also was able to put activity indicator inside the center of root UIView.
Now the things get a little bit complicated when using UICollectionViewController where its root view is UICollectionView. I need to update some code of other guys and they put activity indicator inside UICollectionView (in storyboard). The problem is this activity indicator gets hidden when cells are reused because activity indicator view is the most bottom one. I was unable to change visibility priority storyboard and also this code in view didLoad is not working:
[self.itemsCollectionView bringSubviewToFront:self.activityIndicator];
Because labels, images and etc. views of collection view cell are placed later, during collectionView:cellForItemAtIndexPath:. I could try to call bringSubviewToFront: in collectionView:cellForItemAtIndexPath: but that would be a wrong decision. Any ideas how to achieve this when using UITableViewControllers or UICollectionViewControllers?
IMHO the only reason to use UITableViewControllers or UICollectionViewControllers is because static cells are not shown storyboards when designing layout.
UPDATE It appears iOS wraps UICollectionView inside UICollectionViewControllerWrapperView. Tried to add activity to this wrapper view in viewWillAppear:
[self.itemsCollectionView.superview addSubview:self.activityIndicator];
But with no luck - activity indicator is still is below the cells.
I'v ended in refactoring existing UICollectionViewController in storyboards: I'v opened storyboard xml file with TextEdit, searched for the screen and changed its type from collectionViewController to viewController because was unable to find another way how to change the type of controller, though I hope there will appear some more elegant way for that in the nearest future. Then, I'v wrapped collectionView inside root view and placed activityIndicator inside this view. It's proven classical approach that works like a charm.
I'm trying to change the size of a tableView I have in interface builder and can't seem to. When I first started the app I could drag it around and stretch the sides but all of a sudden I can't adjust it. I tried to delete my tableView and add a new one but the same thing happened. Thanks in advance. Here's what I see when I try to change the size:
if your using a UIViewController you can drag and drop a tableView and can place in a custom position you want. but if your using a UITableViewController you cant move the tableView to your custom position. if you want to do it in UITableViewController you can do like below
if you want your tableView content should show from a point, that you want you can do this way,
[self.tableView setContentInset:UIEdgeInsetsMake(100,0,0,0)];
else if you want set your tableView to a frame in UITableViewController you do this way,
- (void) viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
self.tableView.frame = CGRectMake(0,100,320,300);
}
hope this will help you.
What kind of view controller are you using to manage your table view? Since you show "prototype cells", I'm guessing it's a UITableViewController. Those are built to fill the entire screen with a single table view (which has always annoyed me.)
Starting with iOS 6, though, you can create a "container" view in another view controler, and then drag an embed segue from your container view onto the table view controller. That does all the housekeeping to make the table view controller a child view controller of the other one, and then you can make it whatever size you want.
If you don't want to use a UITableViewController as a child of another view controller, you can use a regular view controller and wire up the data source and delegate methods yourself. However, things like static table views and prototype cells don't work then.
Hopefully this helps someone still coming across this problem. What I did was make sure the UIViewController had a UIView as its direct child, then dragged the UITableView as a child of the UIView, this allowed me to resize the UITableView.
I have made a table view using prototype cells on tableviewcontroller from storyboards.
I want a floating button over that uitableview. (button won't scroll with the tableview).
While searching for a solution..I found out that it is possible by adding button to the superview (in that case Uiviewcontroller subclasses Uitableview).
Can any one tell me how to do that using storyboards??
I think best thing you have to do is to create a UIViewController and add it a UITableView. Then you can add also the UIButton you want to the view controller's view. Don't forget to set the view controller to be the delegate and data source for your table view, and to add <UITableViewDataSource,UITableViewDelegate> to your view controller interface.
If you must do it using Storyboards and not in code, then you need to use a UIViewController and not a UITableViewController.
Add the UITableView and make it full screen - link up its Delegate and DataSource to the UIViewController and adhere to the two protocols in the .h file of your UIViewController.
When adding the button, drag it into the view hierarchy in the "Document Outline" sidebar, and not by dragging it onto the UITableView. Be careful if you're ever dragging the button around the view because if you drag and drop it on top of the UITableView then it will become a subview of the UITableView. If you want to move it around you'll need to select it and then use the arrow keys.
Anyway, apart from that it should all be very easy - add your constraints to keep it in the right place and you should be able to use the button as normal.
I've followed the CS193p on Itunes and am programming now my own app. In the course they have a CoreDataViewController (which is a subclass of TableViewController with all the necessary NSFetchedResults methods in it). With this I got every tableview running quickly. However I want no a view (at the top of my screen) with table view below for only about half the screen.
I've only found tutorials how to embed a normal table view into a normal viewcontroller and hook up the datasource and delegate outlets. But how would I do this with the NSFetchedResultsController?
I guess I have to do it the same and then copy all the functions from the original CoreDataViewController in my own viewcontroller to handle the fetched results?
Or how would i do that?
I have not seen how the CoreDataViewController was implemented. But yes, you would follow the normal step to set the NsFetchedResultsController. Or you can just create an instance of CoreDataViewController and add its tableView view to the bottom half of your view controller's subview.
