I'm starting to get into Mac OS X development and I have a problem the solution to which I haven't been able to figure out for the last three hours (I've googled a long time).
Test application:
I have an application that has a MainMenu.xib, which displays a window - so far so good. I've created another XIB and NSViewController subclass that contains a view which I want to display within the main window. I use the following code to load the view and insert it into the main window:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
// Insert code here to initialize your application
self.compartmentViewController = [[SelectCompartmentViewController alloc] initWithNibName:#"SelectCompartmentViewController" bundle:nil];
[self.compartmentViewController.view setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];
[self.compartmentViewController.view setFrame:[self.contentArea bounds]];
}
compartmentViewController is a property and self.contentArea is a custom view on the main window - like a placeholder.
This works fine so far.
Problem
Then I decided to check out the localization feature. I've localized a couple of strings and both XIBs. At first I was a bit confused by not seeing any localized values. That was until I found out I had to clean the project - since then I've been getting the following error when running:
2013-03-19 22:48:59.763 Vocab Box[10160:303] unable to find nib named: SelectCompartmentViewController in bundle path: (null)
2013-03-19 22:48:59.764 Vocab Box[10160:303] -[NSViewController loadView] could not load the "SelectCompartmentViewController" nib.
Suggested solutions I've tried to no avail
Cleaning the project doesn't help
Checking the build configuration - yes, the bundle resources seem to be ok
Yes, if I remove the localization for my subview and re-add the original XIB, things are fine again (though of course the view is not localized)
Help
I don't have an answer as to why this happens. But I had the same problem, and I fixed it by closing xCode and opening it up again, believe me.
Try the following :
select your project
select "build phases"
add the new xib in the "copy bundle resources"
I just had this same issue and was able to solve it by doing the following:
1) Select the XIB in the project navigator
2) In the File Inspector, uncheck any items under Localization (it will prompt you - make sure 'delete files from disk' is unchecked, and press Remove)
3) Manually add the XIB back into the project

I created a project in Xcode 6 beta 2, which initial had a storyboard. I wanted to work with separated xibs so I removed storyboard and line related to storyboard from Info.plist and added several xibs. Now the problem is that I can't connect file's owner 'view' outlet (because it's not visible) to view from xib. First thought was that I misspelled name of the file's owner custom class name (from Identity Inspector), but I didn't. Also file's owner class is a UIViewController child. I don't know that the problem can be. Did some faced this issue ?
It's probable that you need to close Xcode, clean the project and try again. I created a new project without storyboards and I did the following:
1) I created the nib file.
2) I created the UIViewController class.
3) I opened the nib and selected the File's owner tab. Then I wrote the name of the custom UIViewController class.
4) Without selecting the file's owner tab on the Placeholders left bar (make sure of this) go to Connections inspector tab and you should see the view outlet.
Simply cleaning, quitting Xcode and re-opening fixed it for me.
So this is just bizarre. If I create a custom Table View Controller as a subclass of UITableViewController, I can't reliably edit the .m file. When I click on it, I can see everything in the file, but I can't actually drop the cursor in to edit the code; it stays fixed in the top-left of the screen. Anything I type will appear, and any code already in .m that happens to be on that line will randomly appear. It's like a static image of the .m contents are on the screen, but the actual text is hidden.
Eventually the entire editor just goes blank. Everything else works fine. I wiped Xcode with app cleaner to pick up all the loose com files, restarted, re-installed Xcode from the dmg and re-created the project and still have the same problem (this is under Mavericks, by the way).
Granted, Xcode 5 doesn't seem to have this issue, but I'm quite new to programming and am following a course that's based on Xcode 4. And at this point the issue is just so stupidly weird that I want to figure out what's going wrong. Any insights?
I've given up. If for some strange reason someone happens on this question and has the same problem, it's not worth the energy; just head to Xcode 5 and live your life bizarre-error free (for now, heh).
I was having the same problem. I just cleaned the Build Folder and everything seems to be working perfectly now. You clean the build folder by selecting Product, hold Alt, and then "Clean Build Folder.
I too had this problem after upgrading to XCode 5, then downloading and installing XCode 4.5 (without removing Xcode 5). What I wound up doing was to create all my new UITableViewController files (File->New File->Objective C Class) as UIViewController files, then modifying the parent class to UITableViewController in the .h file.
This is a real 'WTF?' moment for me.
I copied some classes out from another project, including copy and pasting the code and some UIBulder components. What did NOT get copied was the XIB file (I went from XIB to storyboard).
My tab / swipe recognizers aren't activating, and when I drill down the only thing I can discover that can explain it is that somehow, someway, I'm hooking up against the XIB file. (When I click on the little button next to the IBAction/IBOutlet lines in the header, it shows me both the storyboard and the xib file as connected).
I'm not referencing that file anywhere that I can find, it's just somehow magically recognized in Xcode. I don't know what to do, how to fix this.
Anyone have any ideas?
Edit: The really annoying bit is that the file doesn't appear to be in my files list when I check there, I can't just delete the reference that way. And since it's referencing the file in the original project, I can't just delete it. (Any changes made in either project cause changes in BOTH projects; their both using the same xib file for some reason). I should be able to simply delete the reference to the xib file, but I can't find the reference.
If you copy the view controller code from one project into another project you will notice a strange thing happening with the outlet. It is referencing the view from the first project without you ever connecting any outlets.
If you left click the little circle and click the reference link you will even be taken to the storyboard view in the other project. Trying to figure out how to get rid of this reference can drive you crazy.
Well, the good news is that there is really nothing for you to fix. You didn't copy over some deep, hard to find referencing link. Xcode is just getting confused because the View Controller and the outlet name are the same in both projects. Basically just ignore what that little circle says. You can close the first project and Xcode will figure things out eventually. Right click your views in the storyboard to see what referencing outlets really exist in the current project. (See my fuller answer for more details.)
No need to delete Derived Data. That doesn't solve the problem anyway. Just try opening both projects at the same time again and you will get the same strange behavior.
The way I figured this out was to separately create two new projects that had view controllers with the same name and a referencing outlet with the same name. I never copied anything but Xcode showed one was referencing the other. Like I said, ignore the little circle.
I just had the same problem. What solved it for me was to close both projects, delete the derived data from both and then reopen the destination project.
I agree, it's a crazy problem.
I'm sure that this problem could happen and I fix it deleting the content of the Derived data folder of XCode.
I just want to add the steps of how to delete those files:
Don't Delete the DerivedData folder.
Go to preferences (Command ,) > Locations Tab
On Derived Data you are going to see the path, clic the right pointing arrow (that will open that location in Finder)
Close XCode
Select all the files inside the DerivedData Folder (do NOT select parent folder) and (Command Delete) or move them to the Trash and then Empty Trash
Open the project and you are done
I hope it helps someone
unless the xib file is in the project. it should not have a link to it.
the xib file connects to the .h file. not the other way around.
You may want to remove the connections in the storyboard and re-connect them.
Also make sure that the storyboard is the UI being started and that the item on the navigation stack is actually the storyboard page. But you should be able to connect both the storyboard and the xib file to the class at the same time. You just cannot connect one IBOutlet to more than one object in a single ui component (e.g. two buttons on the storyboard cannot both be connected to #property IBOutlet UIButton *myCurrentButton you must have a separate IBOutlet for each connection. On the other hand, any number of actions can be connected to an IBAction. which is why you get (id) sender on each action.
I dont know if this is exactly what you are experiencing, but I hope that understanding helps you debug your issue.
I have been working with Xcode 4.2.1, but following some tutorials and videos from the earlier version of Xcode.
As usual I had the problem with the Windows Based Application. I created a empty application for my Windows Based Application project and was following some steps from the same forum of how to add a MainWindow.xib file to my project using this post
There is no .xib file when I create a new "Empty Application" in XCode
I also followed one more post which has some good screenshots:
http://www.trappers.tk/site/2011/06/16/mainwindow-xib/
Now my problem is I cannot ctrl+drag of the window outlet from the App Delegate object to the Window object. The reason is I could not find out the window outlet from tze attributes menu. One can see the screenshot of how it is looking in my xcode:
And below one can see how it should have a windows outlet for the App Delegate.
Is there anything I am missing or left something behind before coming there. I followed the steps exactly as mentioned in the above posts. I tried creating new projects just to make sure Im doing everything correct.
Any information regarding this would be appreciated.
Thanks
Raaks
From your tutorial..
http://www.trappers.tk/site/2011/06/16/mainwindow-xib/
The answer to your problem is Simple(and also this is the way you should do most of the time in future..)
1) Click on File's Owner(In the placeholder section..left to the xib).
2) In the attributes section you will see a window Outlet..
3) Drag window from the attributes section(right click-drag or ctrl-drag.) and drop it on window in Objects window..(left to the xib)
Hi i get problem with xCode 4.
I develope project with XCode4 on home and on work.
And i store it on my USB flash drive.
Today i get some problem.
I open xib file for add outlet to code and get next error "Could not insert new outlet connection: Could not find any information for the class named ..."
Class exist and property of xib file setted correctly.
Could not insert new outlet connection: Could not find any information for the class named
Ok, think i, i write code and the connect using Files owner.
Next step i open code editor of .h class file and try to write UI... and see nothing. i dont get list of classes UI types
Next i saw what XCode code editor does not highlighting classes of UIKit and else frameworks too.
But i dont have this error on another projects and on it project but on home computer.
Some body have same problem?
Try this: Close your project. Choose Window > Organizer from the main menu. Select the Projects panel. Select and delete all copies of your project from the list. Open the project again (Xcode will rebuild the necessary information).
This will not delete your project, but the index and other information Xcode discovers about your project. As I said, Xcode will rebuild the information as soon as you re-open the project.
We had a really similar problem happen to us and none of the help out there worked. What did end up fixing it was deleting the .m and .h file from xcode (resource only) and then dragging them back into the project from the project folder. It seemed to relink everything and make it work again.
Just add .m files in Compile Sources under:
<My Project>
-- TARGETS <My App Name>
-- Build Phase tab
-- Compile Sources
It fix the problem.
I noticed that .m file was moved inside en.lproj folder.
Just delete (reference only) the .m file from the Xcode and moved .m out of the en.lproj.
Add it again.Don't worry, you will get all your connections back.
It will fix the issue.
