I added a new nib file to my project, and tried to load it.
However, when I click on the toolbar icon that is supposed to take me to the view that I created, I get an NSInternalInconsistencyException with the message:
Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: '-[UIViewController
_loadViewFromNibNamed:bundle:] loaded the "..." nib but the view outlet was not set.'
So I opened up my nib file, and I see for the view that there are no referencing outlets set. However, I try to click and drag the circle for "new referencing outlet" to File's Owner, but it won't let me...what do I need to do to get my view to display?
Here's what worked for me:
Open the XIB file causing problems
Click on file's owner icon on the left bar (top one, looks like a yellow outlined box)
If you don't see the right-hand sidebar, click on the third icon above "view" in your toolbar. This will show the right-hand sidebar
In the right-hand sidebar, click on the fourth tab--the one that looks a bit like a newspaper
Under "Custom Class" at the top, make sure Class is the name of the ViewController that should correspond to this view. If not, enter it
In the right-hand sidebar, click on the last tab--the one that looks like a circle with an arrow in it
You should see "outlets" with "view" under it. Drag the circle next to it over to the "view" icon on the left bar (bottom one, looks like a white square with a thick gray outline
Save the xib and re-run
This is Josh Justice proposal, but in a graphical way (pictures are mine):
Select File owner
On right hand side panel select custom class.
Enter the custom class name
On right hand side panel select oultets
Drag view outlet to view component
Finally the View Controller is instantiated with the rolling code:
PTFilterUserVC *aFilterUserVC = [[PTFilterUserVC alloc] initWithNibName:#"FilterVC" bundle:nil];
//OPTIONAL.This is how 'I' am interested in present the view controller.
[self.navigationController pushViewController:aFilterUserVC animated:YES];
I can generally fix it by remaking the connection between File's Owner and the view. Control-drag from the File's owner to your View (in IB) and select view from the pop-up menu.
The View Identity - Class Identity was not set. After setting it to the appropriate class, the issue was resolved.
Are you sure you have a UIView (or subclass) assigned to the "view" property of yourViewController?
Right click on "File Owner" in the left pane of the xib for yourViewController and verify that the "view" outlet is set.
If not, set it to a view!
this will definetly fix the Issue
For me all the things stated here https://stackoverflow.com/a/6395750/939501 were true but still it was throwing error, reason was I created a View class with name ABCView and then deleted it later I added a view controller as ABCViewController so somehow it was referring to old ABCView in new view controller, I had to delete the ABCViewController and add a new one with different name that solved my issue.
Thanks
I had the same issue with XCode 4.6.3. I had started out with a couple files named MySettingsView.h and .m but deleted them in favor of MySettingsViewController.h, but despite trying most of the hints mentioned here, it still kept erroring with,
2013-07-05 11:48:17.205 MyApp[39024:c07] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason:
'-[UIViewController _loadViewFromNibNamed:bundle:] loaded the
"MySettingsView" nib but the view outlet was not set.'
It was evidently still "confused", trying to load MySettingsView.xib instead of MySettingsView Controller.xib. Maybe its "do what I mean" logic is too fancy.
So I worked around the problem by hardcoding the NIB/XIB name in MySettingsViewController.m:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:#"MySettingsViewController" bundle:nibBundleOrNil];
}
I ran into this problem in a slightly different way from the other answers here.
If I simply created a new xib file, added a UIViewController to it in Interface Builder, and set that UIViewController's custom class to my view controller, that resulted in the "view outlet was not set" crash. The other solutions here say to control-drag the view outlet to the View, but for me the view outlet was greyed out and I couldn't control-drag it.
I figured out that my mistake was in adding a UIViewController in Interface Builder. Instead, I had to add a UIView, and set the Custom Class of the File's Owner to my view controller. Then I could control-drag the view outlet of the File's Owner to my new view UIView and everything worked as it should.
To anyone that is using an xib method to create a UIView and having this problem, you will notice that you won't have the "view" outlet under the connections inspector menu. But if you set the File's Owners custom class to a UIViewController and then you will see the "view" outlet, which you can just CMND connect an outlet to the CustomView.
My issue with this was caused by having a duplicate nib in the class folder that did not have the view set. xcode seemed to be choosing one nib for a build and then the other the next time I built the project. Just deleted the other one. Looks good. Doh!
Just spent more than hour trying to find out why my view property is not set in my view controller upon initiating it from nib. Remember to call "[super initWithNibName...]" inside your view controller's initWithNibName.
I just fixed this in mine. Large project, two files. One was "ReallyLargeNameView" and another was "ReallyLargeNameViewController"
Based on the 2nd answer chosen above, I decided I should clean my build. Nada, but I was still suspect of XCode (as I have two identical classes, should abstract them but eh...) So one's working, one's not. File's owner names are so far as copy and pasted, outlets rehooked up, xCode rebooted, still nothing.
So I delete the similar named class (which is a view). Soon, new error "outlet inside not hooked up" literally was "webView not key value" blah... basically saying "Visual Studio's better". Anyway... I erase the smaller named file, and bam, it works.
XCode is confused by similar-named files. And the project is large enough to need rebooting a bit, that may be part of it.
Wish I had a more technical answer than "XCode is confused", but well, xCode gets confused a lot at this point. Unconfused it the same way I'd help a little kid. It works now, :) Should benefit others if the above doesn't fix anything.
Always remember to clean your builds (by deleting off the simulator too)
The previous answers almost solved the problem for me, but the last step was missing.
Create a xib and swift file with the same name.
Set the file owner to be the UIView subclass.
Drag an outlet from the View to the UIView subclass, name it "contentView"
Add this custom initializer so when the xib loads it attaches the contentView
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
Bundle(for: self.classForCoder).loadNibNamed("SampleView", owner: self, options: nil)
addSubview(contentView)
contentView.frame = self.bounds
contentView.autoresizingMask = [.flexibleHeight, .flexibleWidth]
}
Now any #IBOutlets you add will be attached.
Cheers,
Richard
I also had the same problem and my issue was that i added an other Localisation (English) to the ViewControllers nib so my App with the Localisation German could´t find the nib with the Localisation English!! Hope this helps anybody!
I had face the same problem while accidentally deleted xib reference and added it again.I just fixed by making connection between Files owner and the view.Also make sure that your FilesOwner's custom class is your expected viewController.
For me, the problem was caused by calling initWithNibName:bundle:. I am using table view cells from a nib file to define entry forms that sit on tableViews. As I don't have a view, doesn't make sense to hook to one. Instead, if I call the initWithStyle: method instead, and from within there, I load the nib file, then things work as expected.
I had the same problem, but a slightly different solution was called for. The problem in this case was the class of the File Owner, rather than the class of the View. To set this, I had to click the "backwards play" icon in the lower left corner of the Interface Builder window, and options then appeared that isolated the characteristics of the File Owner, the First Responder, and the View. Clicking on the first one (a large transparent box), enabled me to then set its custom class as suggested above.
I had the same problem, but a different solution was called for. The problem in this case was the class of the File Owner was not connected to xib file.
I ran into something very similar tonight, with a Swift UIViewController subclass. In this case, none of the above fixes worked, but reordering my code a bit did. Net-net, having an extension to the subclass occur before the subclass's definition itself in the same file seems to confuse XCode, despite compiling fine; the fix was to place the extensions after the subclass's definition.
I've posted the details in an answer to this similar question.
In my case , the designated initializer - (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil in ***ViewController class was implemented so even if when I call other initializer to initialize the object ,the designated initializer will be called .
So to resolve this problem checking wether the - (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil is also a proper way.
My problem was in wrong classes. I used custom .xib for my custom view.
Correctly it has to be set like here:
View shouldn't have a class
Class which is used with the .xib is set in File's Owner tab
Outlets are connected to File's Owner and not to the View.
Just had the same error in my project, but different reason. In my case I had an IBOutlet setup with the name "View" in my custom UITableViewController class. I knew "view" was special because that is a member of the base class, but I didn't think View (different case) would also be a problem. I guess some areas of Cocoa are not case-sensitive, and probably loading a xib is one of those areas. So I just renamed it to DefaultView and all is good now.
select the files owner and goto open the identity inspecter give the class name to which it corresponds to. If none of the above methods works and still you can't see the view outlet then give new referencing outlet Connection to the File's Owner then you can able to see the view outlet. Click on the view Outlet to make a connection between the View Outlet and File's owner. Run the Application this works fine.
In my case, the view was not viewed in xib.
in xib the View was size = none (4th tab right hand). I set size to Freeform and reload xCode.
view was appealed and I set the proper link to View.
If you have tried everything and you still get this error, try re-creating the class file from scratch but remember to select the "Also create XIB file" check box. This will auto link up a few items that are not linked when creating these files separately. After this is created, you can likely cut and paste everything onto the new XIB and it should work fine.
I am finding this issue specifically with creating files separately in Swift.
for me it happened, when
I have a ViewController class ( .mm/h ) associated with the Nib file,
UIView from this ViewController has to be loaded on the another view as a subview,
we will call something like this
-(void)initCheckView{
CheckView *pCheckViewCtrl = [CheckView instance];
pCheckView = [pCheckViewCtrl view];
[[self view]addSubview:pCheckView];
[pCheckViewCtrl performCheck];
}
Where
+(CheckView *)instance{
static CheckView *pCheckView = nil;
static dispatch_once_t checkToken;
dispatch_once(&checkToken, ^{
pCheckView = [[CheckView alloc]initWithNibName:#"CheckView" bundle:nil];
if ( pCheckView){
[pCheckView initLocal];
**[pCheckView loadView];**
}
});
return pCheckView;
}
Here loadView was missing,,, adding this line resolved my problem.
I had the same problem, I figured out and it is because of i had ticked "Static cells" in the properties of Table View under Content option. Worked when it changed to "Dynamic Prototypes". Screenshot is below.
I had a similar problem with Xcode 9.3, and setting "Module" under the "File Owner's" attribute inspector to the project module fixed this for me.
Open your storyboard file where your viewController exists, or XIB related file with textEdit.app and check if the storyboard or XIB name is the same of your viewController, then change it, save and reload/restart Xcode.
If you're using a custom init method, check that you're returning something valid. I ran into a piece of code that crashed on something like this:
- (id)init {
self = [super init];
if (self) {
CustomController *controller = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass(className) owner:self options:nil];
} return self;
}
In another class, the controller was created like so:
CustomController *controller = [[CustomController alloc] init];
The problem is that in the init method, self hasn't changed and should look like this instead:
- (id)init {
self = [super init];
if (self) {
CustomController *controller = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass(className) owner:self options:nil];
[controller viewDidLoad];
self = controller;
} return self;
}

Not sure what the problem is here, I've tried:
Cleaning, rebooting Xcode/Computer
Clearing Derived Data
Relinking outlets
I don't have this problem with any other outlets in any other views. Here are some photos:

EDIT: It was a really silly mistake -> misspelled the identifier in my tableView method. Thanks for all your help though!
Did you set your custom cell class in Identity Inspector?
Identity Inspector
Did you try delete outlet and drag outlet again?
Are you referencing to correct custom class? Double check this. I am often using another class unwillingly and than I realized that I am in wrong file.
I think its a normal behaviour, try loading your VC in the storyboard and add the assistant editor on the right. Mine does the exact same thing when i go to my code straight without loading the VC in the storyboard. Can you also show how you set the textLabel?
Current Setup
I have a subclass of a UIView that loads a content from a xib file - call it a XibOwnerClass. Also, among other classes, there is a class called Triangle which helps me to create triangles with or without a border, with different stroke or fill color etc. That class is designable in storyboard and some of its properties are defined as IBInspectable.
Currently, in my xib file, I use this triangle view and setup its inspectable properties through IB. And that is really cool and convenient... So if I look into xib, I will actually see the triangle view among other views.
So, lets go further. In order to use this XibOwnerClass, I drag the UIView element to the storyboard, and change its custom class to XibOwnerClass, so I get my designable properties specific for XibOwnerClass. So, I can setup all things in IB and when I run the app, everything works.
The problem
Even if this works, I wonder if there is a way, to have multiple views (of class XibOwnerClass) dragged on a storyboard, and to be able to configure all of them individually trough Interface Builder?
Currently when I drag the UIView and change its custom class to XibOwnerClass I see nothing. I mean, the view is there, and it has its standard properties + inspectable properties. But I can't see triangles defined in xib in this new view. Is there a way to do this?
I am aware that xib is reused in my case (and it is meant to be used like that), so if I change something in a xib, all views that load from it will be affected. But is there a way multiple views to load from the same xib, but when loaded, to see them & setup them individually?
Here is how I load from xib:
-(instancetype)initWithCoder:(NSCoder *)aDecoder{
if ((self = [super initWithCoder:aDecoder])){
UIView *myView = [[[NSBundle mainBundle] loadNibNamed:#"MyXib" owner:self options:nil] firstObject];
if (myView){
myView.frame = CGRectMake(myView.frame.origin.x, myView.frame.origin.y, self.frame.size.width, self.frame.size.height);
[self addSubview:myView];
//Initialize other stuff
[self commonInit];
}
}
return self;
}
Then in awakeFromNib: I use the values of inspectable properties...
EDIT:
Also I don't have initWithFrame: implemented, but I thought that it is not needed if load from nib (because it is not executed). But maybe this is needed while design time ?
can't really say what's wrong when you don't share class codes. but i guess you didnt use prepareForInterfaceBuilder. in your XibOwnerClass override prepareForInterfaceBuilder and call setups for view inside it for example change background colour or so.
override func prepareForInterfaceBuilder() {
//prepare setups or things to show in storyboard
}
Okay, I have solved it. It turned out that I shouldn't use Main Bundle but rather bundle for that class, like described here.
So here is the code:
NSBundle *bundle = [NSBundle bundleForClass:[self class]];
#Mohammadalijf's answer in general is correct. It is just not a direct solution for my issue. But later on, when I fixed bundle thing, I used prepareForInterfaceBuilder like he said, and initialized things there so everything was available at design time.
Some useful stuff related to all this can be found here as well.
I am running XCode 7.1 and running on device(iOS 9) - (not simulator). I am loading up a nib file by name as such:
MyDetailsViewController *myDetailsVC = [MyDetailsViewController initWithNibNamed:#"MyDetails" withNotificationCenter:notificationCenter];
this is simply just a class method that i have set up that loads up the xib via the mainBundle. The xib file is just a UIView with a tableview inside of it everything seems to be hooked up properly. However, when loading the nib(viewWillAppear, viewDidLoad etc hasn't executed yet) from the bundle I get the error:
NSUnknownKeyException, reason: '[MyDetailsViewController setValue:forUndefinedKey:]:This class is not
key value coding-compliant for the key tableView'
I know that I am not getting back some generic view controller because it spells out very clearly what view controller we are talking about. The File Owner seems to be hooked up properly and its Custom Class is set to MyDetailsViewController. Even when I hover over the IBOutlet 'circle' in code the tableview highlights as well as when i hover over the menu when checking the outlets.
Something that may be totally unrelated is the internal error message in the xib file, it may or may not be related to my problem and i've never seen it before. The beginning of the log file that you get from that error is:
Can anyone help me determine what is going on here? I would appreciate it.
here are a few more screenshots:
Before init you should call alloc first:
// MyDetailsViewController *myDetailsVC = [MyDetailsViewController initWithNibNamed:#"MyDetails" withNotificationCenter:notificationCenter];
MyDetailsViewController *myDetailsVC = [[MyDetailsViewController alloc] initWithNibNamed:#"MyDetails" withNotificationCenter:notificationCenter];
I have created a custom view (Quantity View) with nib file in Swift. I have created some IBOutlets & IBActions (for buttons, labels etc.) in my custom view.
I tried to use this custom view (Quantity View) by assigning class name to a UIView in my storyboard.
It's showing me all the IBOutlets & IBActions in the Connections Inspector, as shown in this screenshot: .
I just want to show only delegate for the Custom view.
Possible Answer:
I thought I can use the -viewWithTag to get the views instead of Outlets.
But, I want to know if it's possible with having Outlets also or if there is much better way to do this?
What are the other possible ways (optimum) to handle this situation?
You can also consider the following solution:
You can take the subviews of your QuantityViews(custom view) and you can identify the specific views by its frame origin.
Note : you should know the customview subviews frame
Its not possible to hide IBOutlets from storyboard if you declare the class members as IBs (IBOutlets or IBActions).
The IBOutlets or the IBActions are just indicators to the interface builder so that it can show the names on it when you try to bind them it actually calls the setValue: forKey: method to set the view's reference to the IBOutlet property.
Now if you try to access an subview from the file's owner class without any IBoutlets you need to have a pointer to point it, so for that either you can get the reference using ObjectID which is assigned to the subview by the interface builder or you can get it using the viewWithTag: method.
The ObjectID you need to find all time when you add or replace a subview from the view, so better and convenient approach is to use tag property of UIView class.
So my conclusion to this problem is to access the views using the viewWithTag method you mentioned earlier.
I think your way is correct. But sometimes Xcode doesn't work correctly.
The following makes the IBOutlets and IBActions reappear and work properly:
Clean project your project in Xcode.
Quit Xcode completely.
Delete all contents of ~/Library/Developer/Xcode/DerivedData/.
Restart MacOS just in case.
I hope you will resolve that :)
Firstly I have inspected all of the other questions on this topic: the answers provided seem to be:
make sure you set the file's owner to your custom view controller class (which I have done)
make sure you have a referencing outlet from the view to the file's owner (which I have)
My code is compiled to a static library, and I export the .a file and xib file.
My example app that uses it includes the xib in its bundle ("copy bundle resources" in build phase)
In my library code I have a function in a separate UIViewContoller subclass to create the view controller from the nib:
- (void) presentCustomController
{
self.vCtrl = [[CustomController alloc] initWithNibName:#"CustomController" bundle:nil];
...
}
When I run the example app, I inspect the _view member of self.vCtrl, and it is 0x0000, and of course this is what causes the exception in the posting title.
My understanding was that the view to which that member points was 'auto generated' from the xib file, and it's children were the controls that I have put in it (buttons etc).
What part of my understanding has fallen down? Is the problem related to the fact that it is in a static library?
Thanks for any help.
If you are 100% that you connected your View to the File's Owner then I suggest you do the following:
Clean the project (cmd+shift+K) or Clean Build Folder if you prefer (cmd+shift+alt+K)
Quit Xcode
Restart Xcode
That should fix it hopefully.
Do you have multiple targets?
make sure you set the file's owner to your custom view controller class (which I have done)
I have come across a similar issue where I thought that I was setting the file's owner's custom class, however, IB was not actually setting it. Open the XIB as its raw xml and search for the custom class name.
For me it was because the .m of the view controller was not included for my specific target. To fix this check all the boxes in the target membership pane.
