I have lots of images in my xcode project for iPhone application. i have changed some of images in last 2-3 version but now i want to remove unnecessary images from that.
I tried ctrl + Shift + F to find image name in whole project but i am not able to sure that i am using images through xib(interface Builder) or not.
so how to find images are in use through xib file or in project or let me know if you have any other trick for this.
Try Slender, it's designed just for that :

In the playground app, I am trying to upload an image, I google it and many solutions said that I need to put my image to resources. But the case is that in the new playground app, the is no resources folder that's why I couldn't add my image. There are shared Sources and Xcode sources but in these files, I couldn't put my image.
this can be an easy question but the case that I struggle with. And in order to continue my project, this point madden me. Thanks
as you can see, there aren't resources that ı could put my image
there is space for adding an image but in this case, the problem is that after ı chose my image nothing happened
UIImage can be loaded to the Playground app like this,
File --> New Blank Playground.
Click on the '+" icon on the top right corner and choose the picture by clicking Insert from... option.
Load the image with its name from the Playground.
UIImage(named: "test.png")
Output with loaded image
This seems to me as a bug because I have changed images with:
someImage.image = [UIImage imageNamed:#"anotherImage.png"];
and I have never had a problem. so let me show you what I have:
I have placed an UIImageView:
note that imgObjetivos is conected to this UIImageView.
I have a method that get's called when clicking the following button:
and the method contains:
as you can see I just want to change the current image with:
so when I run the application in the simulator everything looks great:
and when I press the button the image changes successfully:
Now why is it that when I run the application on my iPad the image does not change!? when I press the button the image disappears instead of getting a new image like in the simulator. I just learned objective-c and I am starting to dislike it. What am I doing wrong?
EDIT
I found a solution I changed the name of the image and now it works:
but this makes no sense. Which names works and which ones do not? I also have make sure that I don't have two images with the same name and that is not the case. when I have a few letters after the '_' underscore it does not work. This is really strange. I am starting to dislike objective-c :(
I've had the same problem before. The problem is that the image that you're using to replace the previous image is corrupted or say is not in it's original format.
In my case, I downloaded images in the web which was .jpg format and renamed it as .png format which actually made it .png. so in short term, ipad does not support the functionality for converting image format by just renaming the extension. you have to have a proper converter or something.
I would go with removing the image file from the project, clean the project and add the file back.
I had to rename the image name to something else I don't understand why... I thought that the problem was because I previously deleted that image that contained the same name but that is not the case because I imported the image with a similar name to the solution and I had the same problem. for example the original name of the image was objetivosFoto_h.png and when I renamed to objetivosFoto_ho.png it still did not work but when I renamed to objetivosFoto_horizontal.png it worked.
I am learning iPhone development, and have built a simple app that has an image that changes to another image when you tap it.
If i build it to the simulator, it works fine, but if i build it to the device the images dont appear. i feel like they aren't being copied across. I have checked they have been named correctly and i have made sure i imported them to 'resources'
I dont think it is a problem with the code because i added a thing to also make text appear when the image is tapped, and this works, so a button is still there doing something, it just doesn't have an image on it.
-(IBAction)changeImage:(id)sender {
[fortuneCookieButton setImage:[UIImage imageNamed:#"Image2.jpg"] forState:UIControlStateNormal];
label.hidden = NO;
}
-(IBAction)restoreImage:(id)sender {
[fortuneCookieButton setImage:[UIImage imageNamed:#"Image1.jpg"] forState:UIControlStateNormal];
label.hidden = YES;
}
Does the case (upper/lower) of all your file names match exactly for all letters? Source code & project & Mac?
just to share with you, I had this same problem and I found out the solution: I was using lower case in the file name and upper case in code. The thing is on Simulator there was no problem because Mac file system is case-insensitive but in the iPad it didn't work because iOS file system is case sensitive. ;-)
I had this problem. Bizarrely the image had been working in the past, then just stopped appearing on the device one day.
It was a PNG.
I opened it in GIMP and saved it again. Then it went back to working again. No idea why.
Crazy.
Is it the case with only PNG images or also for JPG & other format you're having same issue. If it's only for PNG image, then it might be possible they're not being compressed. Try the following way.
Select your project target & go into its info. Here go into the build tab. In the configuration select "All Configurations" from Configuration section. Now, write "COMPRESS_PNG_FILES' in the search bar. And see the status of the check-box. IF it's unchecked, then make it checked & it will work. But if it's already checked, then there should be other reason in your project.
In the later case, I would request you to create a new dummy project & check by adding 2-3 images whether it's coming or not.
Clear caches delete the previous build and try again.
I also had same problem, and it was caused by a different reason: my project has image files with the same name! Since my app has many images, I inadvertently included images with the same name. Simulator is more tolerant and show the images just fine; however, when built on device, neither of the images of the same name were copied to the build directory. Obviously xcode is more picky for device: since all images go to the same directory, the file names must be different. When there are files with the same name, xcode refuses to copy any of them since it doesn't know which one to pick.
I have the same problem. In my case, the issues is to do with the UILabel above the UIImageView that shows the image. When I change the type of UILabel to AttributedText (In Property Inspector), my real devices cannot load the image. When I change it back to Plain, it works now. I use XCode 6.2.
on top of all suggestions - it wasn't work for me until I restarted the device
I'm new to MonoTouch and iPhone development. I have my images (PNG) in a resources folder in MonoDevelop, however if I want to set the image property for a button in Interface Builder, how do I do that? It's always a blank dropdown. Do I need to use XCode to access the XIB file and then somehow embed the button image file I'll need in it?
This is a known limitation of MonoDevelop and Interface Builder. To add images to an XIB in Interface Builder they must be part of an XCode project, which of course coming from MonoDevelop they're not.
To achieve what you're trying to do you will need to set the image via code, and ensure the build action of your image is set to Content. To do this, simply right click your image inside MonoDevelop, and select Build Action > Content.
On your view with the button on it, create an outlet in Interface Builder for your button, hook it up, then from code to set your image, you just need to use the .FromFile("path/name") method of UIImage.
UIImage buttonImage = UIImage.FromFile ("resources/image.png");
myButton.SetBackgroundImage (buttonImage,UIControlState.Normal);
That's off the top of my head, but I think that should do it.
You can manually set the image in Interface Builder, but it wont show up until run time. The image name can include a path, e.g. "images/settings.png".
All solutions given here are completely wrong and misleading. All you need to do, is place your images in the Resources folder (on the project root), and add your images to this folder. After adding files to this folder, mark all files and make sure their build action is set to BundleResource.
I also needed this to work, here is a workaround I found.
You need to create a dummy xcode project. Place it in the same folder as your project.
Add all your xib files and image files to that xcode project by dragging them in when the project is opened in xcode. Now you will be able to see the preview of the images.
The image files must be in the same folder as the project file and xcode must be opened with the dummy project while the interface builder is opened.
Not great - but solves the issue for now.
Here is a sample project I have created.
For this issue to be resolved on the MonoDevelop side - some inter-process communication code needs to be created, I think that a good starting point will be looking for "PBXProjectWatcherServerConnection-3.1.2" in google.
I have create an application on iphone using objective-c.In this application i am just displaying different players images stored in one folder, which will be run perfectly on simulator. But when I deploy it on iphone it is not showing the images of the player.
for that the code is:
UIImageView *imageplayer = [[UIImageView alloc]initWithFrame: CGRectMake(imgx, imgy+45,135,150)];
imageplayer.image = [UIImage imageNamed:playerpng];
if(imageplayer.image == nil)
[imageplayer setImage:[UIImage imageNamed:playerjpg]];
if(imageplayer.image == nil)
[imageplayer setImage:[UIImage imageNamed:#"noimage.png"]];
[self.view addSubView:imageplayer];
Plz solve this query.
Thanks in advance
Sometimes xCode doesent update correctly the bundle, try cleaning and building again.
I am currently experiencing this problem as well. I was able to correct it after a bit of debugging and reviewing the build file.
When I do an ls -l, I noticed that some of my png files have a # symbol beside the permissions. When I followed that up with a ls -l#, it showed that the files with an '#' had an attribute set 'com.apple.quarantine'. This attribute is given to a file (often from a zip, jar, or other executable) that is downloaded from the net. You can get rid of this attribute by performing:
xattr -d com.apple.quarantine *.png
Then, select the images in XCode, and check that the checkbox under the target is checked. In my case, it was not, so the images weren't being included in the bundle.
I had the same problem, solved by using all lowercase for the file name in code - image.jpg, but it does not seem to make any difference what case the actual file name is, e.g. Image.jpg
check name of image file. It must be "noimage.png"
not Noimage.png or noimage.PNG
Just to clarify, does the "noimage.png" display, or is the program loading a player image but failing to display it? Or is nothing loading.
These should easily be determined in debug mode.
A few additional things to check...
1) Just for testing, start out with PNG versions of the player files. This is the primary format on the iPhone and might eliminate a file format issue or other anomaly that the simulator is not sensitive to.
2) With regard to fixing in an image editor, specifically make sure that the image is set to a DPI of 72 pixels/inch. The iPhone and particularly Interface Builder are very sensitive to this being correct and will sometimes not display or will display a very blurred version of the image if incorrect.
3) Make sure the image(s) haven't been added multiple times (from different directories and/or to different group folders). We encountered a situation where we had inadvertently imported the same images at two different layers within the project hierarchy and this can cause unexpected behavior within the iPhone (selecting randomly or failing to select).
4) Make sure the Get Info -> Targets has your particular target checked. The simulator may still see the image but it will not get deployed to the iPhone.
5) Make sure you can view the image within XCode and that it looks correct.

This happens to me sometimes. I once spent half a night trying to figure out what was wrong. In this end, this is what worked: open the image with an image editor and save it again. That's all. I'm using the free Acorn image editor to do this. Haven't tried it with Photoshop. (After all, it seems that Photoshop might be responsible for introducing the error in the first place, although that's far from sure.)
I don't know what causes the problem. I usually get it when I use png files that have been sent to me. Could be a simple file permissions problem, or some more subtle problem with the image format. I would be very interested in hearing the opinion of better-informed people.
In any case, if all else fails just try this: open the image with Acorn, save over the original file. Works for me.
Make sure the image files are added to your XCode project.
After some investigation, Michael's comment seems to have a solved it for me. I had all lower case as the file name but was following variable convention and had the png file with an upper case for the second part of the file name. Here my file was putback.png but was referenced in my code as putBack.png
UIImage *putBackImage = [UIImage imageNamed:#"putBack.png"]; //wrong
UIImage *putBackImage = [UIImage imageNamed:#"putback.png"]; //correct
Select correct target while adding image files to your project. Following are steps to make it further clear
Select Add Files to "YourProjectName"
In opening window there is an "Add to targets" option at bottom that shows all available targets
Check target or multiple targets in which you want to add images
Press "Add" button and you are ready to go
