I've created a view on the storyboard in one of my view controllers and realized that I'll need to reuse it. So I then created a subclass for UIView to consolidate the code. I've selected the view in the storyboard and changed the class to my custom view class. Now I want to create #IBOutlets for a couple of the components in the view (in this case, 2 text fields). When I try and drag&drop from storyboard to custom view file, the only thing it allows me to create is an #IBAction and #IBOutlet is grayed out.
I tried creating the #IBOutlet manually in code and then drag from the circle to the component on the storyboard. Everything seemed to work (i.e. I see the connection in the little black popup and also the circle next to the variable is filled in. But when I run the app, the 2 fields are nil.
Is there a reason why I can only create actions and not outlets? (I'm kind of new to iOS dev).
No XIB is needed
Manually write the IBOutlet in your custom UIView class, for example:
#IBOutlet weak var container: UIView!
Open the storyboard and select the custom view in the Document Outline panel on the left.
Open the Connections Inspector on the right. Drag from the Outlet to the custom view in the Document Outline panel to connect them.
If you want to reuse a UIView then best to create an xib of the view and a custom class of the UIView. Then change the file owner in xib class to your custom class. Then you can drag and drop IBOutlets of the components inside the view to custom class. In the storyboard you can use the custom view and change the name of the class of view to custom view. Now drag and drop the IBOutlets from the story board to UIView. You can see the tutorial video on how to do , I have made for you.

Why is my IBoutlet not showing when I try to link a text field to the swift controller view it says insert action instead of IBOutlet. I'm not trying to add an action what is wrong with this new update Is anyone else having this issue.
In connection, currently, you have Action selected. Tap on it to open a dropdown and select Outlet.
Image Source : Here
UPDATE
in Type, you need to select your TextField Class, currently its set to Any. Once you change it, the outlet option will start showing.
Just copy this code and paste above viewDidLoad method.
#IBOutlet weak var passwordTextField: UITextField!
And click the small circle before this line and drag to your text field.
Note: Make sure you've set the view controller class name in storyboard
When you attach #IBActions (or #IBOutlets), you do not want to attach them to Exit Object on the View Controller.
What i get from your image is your class is not set
The problem might be that you are supposing you can form an action connection from a UITextfield in the scene of one view controller to a different view controller. You can't. You can form outlets and actions only between a view controller and the interface inside the same scene of your storyboard.
Make sure your View Controller's class is linked to your file, then go into the Assistant Editor making sure you selected Automatic.
If you have questions, let me know!
Verify that you are using Main.storyboard and not Launchscreen.storyboard
I have a UITableView with static cells in a Storyboard. The static cells are of a custom class. I would like to wire up the outlets for the cell but it seems like this is not supported?
Wiring the views onto the ViewController works, but is rather messy (there are lots of cells). A workaround would probably also be to tag the views, but also not ideal. Any other ideas?
You cannot control-drag your UIView to the source file. However, you can link up the other way around.
In Storyboard, select your static cell, and setup the Custom Class.
In your custom class, add all the #IBOutlet as you need.
Go back to Storyboard, select your static cell, and in Inspector, select Show the Connections Inspector (the last tab).
Drag the Outlets there to your UIView(s).
If you use "assistant editor", you will see the circle in front of #IBOutlet is now filled (hooked).
have you checked custom class of that UITableViewCell. it should be custom file and subclass of UITableviewCell you are created.
I am having issues making UILabels and IBAction buttons in custom classes. Xcode seems to not want me to do it. They way I'm trying to do it is through interface builder (storyboard). I have no issue clicking and dragging to make IBOutlets and IBActions using the main View Controller but when I click and drag over to connect them in a custom class it does nothing. Am I only able to make these in the View Controller? I've attached a pic of me trying to drag over to connect my button in the custom class and you can see that nothing pops up. So basically, Are labels, buttons, text fields etc, for the View Controller class only? Thanks for any feedback.
Within interface builder, you will need to make sure your view controller is using your custom class by opening utilities view on the RHS of the IB, selecting the third icon along (please see picture below) and enter your custom class name in the space provided.
Your custom class will need to be a subclass of UIViewController though, like the picture below, not an NSObject for example.
I'm referring to this line within your .h file ...
#interface MyCustomClassViewController : UIViewController
Your custom class needs to match the UI object you are connecting it with. For example if you had UIView object, your custom class would need to be a subclass of UIView, a UINavigationViewController object, a subclass of UINavigationController etc etc.
I hope this helps.
Select your view controller in the stoyboard and go to the identity inspector, make sure the name there is your custom class name.
Using storyboard in ios7 the content view is explicitly viewed under the Table View Cell in the story board editor (opposed to previous versions where it was hidden from the interface).
The problem is that I cannot connect the cell's custom elements to my custom cell's ib outlets anymore (subclass of UITableCellView) and can only connect them to the table's content view (UIView) which CANNOT be customized (i.e. its custom class attribute is grayed)
This leaves me with the option to use tags which I find inconvenient and less elegant.
I could also create a custom view in a xib, do all the connections and then manually add this custom view as the content view of the table but I am looking for a way doing it via the story board editor.
Is there a way to connect UI elements to a custom cell's content view in the story board editor in ios7 ?
Ok I found an Xcode bug.
If you complete the following this will replicate the issue:
- Create new UIViewController in storyboard
- Drag a UITableView to the VC
- Update the UITableview to have 1(as many) dynamic prototype cells
ISSUE: The cells are added but without a contentView.
RESOLUTION:
Rather than updating the amount of cells in the storyboard.
Drag a custom cell from the objects part of Xcode, the Cell will be added with a contentView.
I was able to do this by doing the following:
Select the cell in the document outline
Change its custom class in the Identity Inspector
Place whatever elements you want into the content view
Connect the IBOutlets to the elements inside the content view using the Connections Inspector
I don't really know the answer, but I can suggest work around this issue:
1) Copy existing cell from other tableview to the one you're working on.
2) You will have contentView under your cell now. Design this cell by adding your views.
3) Create a class for your cell, e.g NewCell, then manually create IBOutlet in this class:
#property (nonatomic, strong) IBOutlet UILabel* mainLabel;
4) Assign the cell class in storyboard to the class you just created. After this step, you can drag the outlet from storyboard to class.
I'm not sure if this is a bug for XCode 5 or it is intended, and I'm looking for better solutions as well.
Create new uiviewcontroller with xib interface and add the required sub-views .Also,establish the iboutlet connections.
Now ,rename the viewcontroller : UIViewcontroller to viewcontroller : UITableviewcell in .h file of your newly created view controller.
Your tableviewcell was created and ready to use with any UITableview of any class.
Hope it helps.
I might be duplicating someone else's answer but I found this workaround which helped bypass this silly XCode bug. Short solution: When you build your custom cell in Storyboard, do NOT drag your UI elements inside the cell or content view.
Instead, drag them OUTSIDE so that they're child elements of the parent table view!
It's easiest to do this drag and drop if you use the little hierarchy menu on the left to make sure your elements wind up in the right spot.
Once the elements are dragged in, just control-click and drag from the custom cell to the UI elements to make your connections. Woo hoo!
Once your connections are set, then (finally) drag the UI elements back INTO the custom cell's content view and lay them out as you normally would.
UPDATE: While my method works, look for a comment by thomasdao in an answer below where he just drags the connections directly into the .h file (the little circles in the left margin where you declare your IBOutlets) -- this is actually the easiest solution but unfortunately it's stuck as a comment.
I'm still new to xcode / iOS and have the following problem:
in order to display some mobile debug information, I have a UIview added/connected as outlet-property to one of my Viewcontroller. This view is a custom subclass of UIview. Now I addeddd some UIlabels as sub views to this view and want to drag the outlet connections from these labels to my customUIview.h file in order to have these labels accessible as properties of my custom UIview class (no need to access them directly from the view Controller).
Problem is that the interface builder (I'm using Storyboards/ xcode4.3) does not make the trick. I can connect the outlets to the ViewControllerClass.h but not to my sub view's .h file.
Can anyone point out where the problem is?
Just solved the problem. After typing the property outlet declarations manually in the customview.h file I could ctrl-drag-connect them from there to their corresponding UIlabel objects in the interfacebuilder. Works only in this direction!
Thanks anyway
Update your custom view class from "UIView" to your "Custom View" class in interface builder.
And now you can make connections just by ctrl+drag your buttons or textfield to your appropriate custom class.
Problem solved! Due to an interesting SO post from three years ago (about connecting to subviews of UIView), I discovered that one merely drags (not Ctrl_drag!) from the action or outlet circle (in the .h file) to the control and that's it. Works perfectly even when the controls are in a different view from the subclassed UIView. Works equally well with outlets as with actions though you always drag away from the circle.
