Could not load the "" image referenced from a nib

I have no images called "" (nothing). I've gone through the .xib file of the screen where this pops up and can't find anything that would cause this. Anybody who have had the same issue? Here is the full warning:

Could not load the "" image referenced from a nib in the bundle with identifier "com.blah.Blah"

Make sure the 'Target Membership' for the 'Assets.xcassets' has been selected.

Click 'Assets.xcassets'
In the 'File inspector', make sure 'Target Membership' selected.

Believe or not, sometimes this happens because some IBOutlet was removed and in the storyboard have the reference to it.

Please do a search for image= shows various results. Select results from nibs or storyboard open it, if there is some value like image="2342D4DF-1E6B-42B8-847A-F9F622921D02" delete it and enjoy.

I got this problem for all of my images after switching one of the label's text to 'attributed' and using one of the 'Fun' fonts. Even though I switch it back to 'plain' I still get the "Could not load..." error - until I re-load and re-reference all of my images again.

I'm using Asset Catalog on Xcode 6. Simply removing and re-adding the Asset Catalog fix the problem

In my case it was because one of my button images was wrongly added to the Background Image container instead of the Image container (in the Inspector). I found it by going through the entire storyboard hierarchy and checking each image and button setting.

Just for reference, this problem is also caused by using .jpg images and referencing them inside of storyboards/nibs. iOS 8 appears to be able to handle the proper type checking between jpg and png images at runtime. However, on iOS 7 and below you will need to manually set the image in the code and remove the image reference inside of the storyboard to get rid of the warning.

Remember you need to manually set the .jpg when referencing jpg images.

[self.imageView setImage:[UIImage imageNamed:@"yourImage.jpg"]];

I had this warning because of a UITabBarItem. In the attributes inspector for the field "Selected Image" I had a file listed that was also the value for the field "Image". Nevertheless, I received warnings until I made the "Selected Image" field blank.

I got this error from an undo action, simply dropping the image back onto the view controller solved the problem.

I had the same issue and in my case there was an UIButton with an invalid image reference in the storyboard file. The reference wasn't empty so it was not trivial to spot by just searching for "" in the storyboard file. However, Xcode did show "Unknown image" for the button in the Background field instead of "Default Background Image". In the storyboard file it appeared as

<state key="normal" title="Use" backgroundImage="0E39AEA8-7F29-40B2-96B1-63B99047E8D5">

so perhaps grepping for backgroundImage and looking for non-familiar references will help find the cause.

I came looking for the answer. I searched my entire project and storyboard source code for "" and nowhere could I find it. The clue that the view that is displayed when the error appears is the one you need.

Open your xib or storyboard selecting the relevant viewController.
On the left click all grey arrows to expand the selection in your view
look for the UIImageView icon (its the one with the palm tree)
select it and open the "Attributes inspector" on the right hand side.
In the ImageView section at the top in either or both Image and
Highlighted you will see greyed out "unknown image".
Use the drop down menu to change this from "unknown image" and build run
voila

I had a very similiar problem which I eventually found. The line below was causing the problem using the open as source code method mentioned above.

<tabBarItem key="tabBarItem" title="Events" 
            image="319365D1-7058-46CD-8420-18E0EAFB2F29" id="a5a-IF-j9f"/>

In xcode 5.1 I had this same issue. The only way I could finally get it to work when using storyboard was to add the images as an image asset catalog. From what I read maybe they changed something in 5.1. I thought that storyboards don't have nibs - so it would make sense that asset catalog replaces the old method.

Project > General > App Icon Arrow > Import New Folder.

As soon as I did that the NIB references went away and my images showed up.

You can do this to check it from your storyboard, or nib. Open it as Source Code:

enter image description here

Then "Find" the image name in it, see if it exists but already invalid in your project, probably you have deleted or changed its name, and now it doesn't seem valid.

The nib (or ultimately the xib) that is the cause of the warning message is the one that is loaded when the message gets written. You then can look at the controls that use images in the inspector and find one where the image name is "Unknown image". You can then clear this value by setting it to some value and then clearing out the value. Note that with UIButton you'll need to try the four different values of "State Config" (Default, Highlighted, Selected & Disabled) to see where the invalid reference might be hiding.

This worked for me:

1- Quit Xcode

2- Make a copy of your .storyboard for backup.

3- Open your .storyboard in a text editor and delete image nodes and image node attributes with empty references.

delete node like this --> <image name=" " .../>
delete image attributes like this --> <tabBarItem key="tabBarItem" title="untitled" image=" " id="6"/>

4- Save the file
5- Open your project again in Xcode.
6- Run Product->Clean
7- Run your project

Warning should be gone.
