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 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.
How should I go about creating a View for the storyboard programmatically? I want to access the labels from the first ViewController object made(automatically to call the IBAction methods of VC). I know that this first object of VC is the one linked to the view in the storyboard(?) and I need to change a label form another file, besides VC. I'm pretty sure the only way to do so would be to access the VC object that is linked to the view, or create one and not go with the default one that is created. If not, how would I go about accessing the labels of the view from another file?
You don't create storyboard objects programmatically. A storyboard is very basically an XML file Xcode uses to call different view controllers. The biggest advantage of using storyboards over NIBs is you can layout transitions or segues, and the advantage of NIBs or storyboards over initiating view controllers by code is obviously the visual interface. So your question doesn't really make sense.
If you want to reference a particular view controller's label from your storyboard you need to create a pointer to that view controller first, but changing it programmatically doesn't make sense because that's what storyboard is for.
That said you may just need to go look for your class name in your view controller's Identity Inspector in storyboard and then edit your label programmatically through an IBOutlet property.
I'm attempting to create an application for iOS, using Xamarin and storyboards. Within this, there shall be a button located in a TableViewController which will navigate the user.
To do this, I've used a Container, embedded to a TableViewController. However, my concern is I wish to add an Outlet from the button within the TableViewController to the ViewController header class - Yet it only allows me to try and add one to the 'UITableViewController.h' file.
What is causing this and how am I able to add the Outlet to the 'ViewController.h' file? (Extremely sorry if this makes little sense)
You should not use both the UITableViewController and the UIViewController. UITableViewController is a subclass of UITableViewController so all you need the UITableViewController and you should drag the outlet to it.
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.
For an ipad application in ioS5.0 using arc and storyboard, i wanted to create another custom view and instantiate several instances of that view within a scrollview so as to show a scrollable train of these custom views. To do this, I created the custom view in XIB file, however, how should I instantiate this view in the ViewController being refrenced within the storyboard. The custom view also has a gesture recogniser within it.
thank you in advance for your help on this.
I don't think there is a way to instantiate a nib backed view from a storyboard. You can do most of the layout in your storyboard, but then you will have to programmatically build your nib backed views and add them to the scroll view.
As a side note, it sounds like you are building something that could be solved with a UITableView and a prototype cell. Here is a pretty good tutorial.
