Mac OS X Lion v10.7.2 Xcode v4.2.1 Build 4D502 gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00) GNU gdb 6.3.50-20050815 (Apple version gdb-1708) (Thu Nov 3 21:59:02 UTC 2011)
I have a bunch of images in my resource folder, but when I delete those images and run in simulator again, the images are still there. I have completely deleted the images from the Project Editor window (not from Finder), and I used DELETE (not Remove Reference Only), and they are still showing up in the simulator. If I add new images back in (with the same names) thru the Project Editor window (not from Finder) the old ones are still being used as well instead of the new ones.
I have tried:
1) Deleting images from Project Editor window.
2) Delete app from simulator (click and hold, then delete while wobbling), then restart computer.
3) Choosing Product > Clean.
4) Choosing Product > Option+Clean.
5) Choosing Show Package Contents of .xcodeproj file, and deleting everything in the xcuserdata folder.
This is an incredibly annoying bug!
How do I tell Xcode to stop using cached images?
I am newbie, so something like "Clean Targets" does not mean anything to me, unless you give me the instructions on how to do it as well.
Thanks
EDIT:
Here is another option we all missed, which might do the same thing as deleting the /Simulator/../Applications folder: In the iOS Simulator menu, there is an option called Reset Content and Settings ... it never occured to me that the simulator was a separate app from Xcode, so I never thought to check menu items while simulator had focus!

Manually removing the build folder may help. Clean does not always do this properly, for reasons unknown. The build folder used to be in the project directory, but now (also) exists in ~/Library/Developer/Xcode/DerivedData/
Solved by original poster:
Oh wait I had a brainstorm because of your suggestion above, and from Terminal I used: find . -name 'myimage.png' 2> /dev/null and I found the secret hidden cache! It is in my user library here: ~/Library/Application Support/iPhone Simulator/4.3.2/Applications/ Just delete everything in the Applications directory. May also need to do this one as well: ~/Library/Application Support/iPhone Simulator/5.0/Applications/

I had the same thing when I was adding transparent background to an image that was already part of the project.
What worked:
1) Delete app from Simulator (long press and hit X).
2) Also I had to remove old image files from project and then reload the new transparent background images into the project.
Also hit Project > Clean multiple times.
回答3:
I had the same. Very strange because the simulator displayed the no longer existing images and the development-phone displayed the correct images.
I had already removed them from the folder. And deleted them from the simulator. For me a Product > Clean did the trick.
回答4:
After I did the "remove fromfolder"/"Reset content and setting"/remove app from simulator", I still had an old image hanging around in the simulator. Then I did a "Project>clean". Then the detailViewController.xib file disappeared from the folder. It is still present in XCode, but can not be found anymore when running the app in the simulator, cousing a crash. What is the problem here?
回答5:
I believe that since Lion, this has changed to '/Users/[user name]/Library/Application Support/iPhone Simulator/[version number]**'. Be careful however, the Library folder is hidden. To view it, open the Terminal and run this:
defaults write com.apple.Finder AppleShowAllFiles YES
回答6:
I had to
1) Delete the images from the folders.
2) Delete the app from the simulator.
3) Clean.
4) Stop the simulator and restart.
Only when I had done each of these could I get rid of old resources
回答7:
I had this issue as well. Deleting the app from the simulator (In the simulator do Hardware -> Home, click + hold on app icon till icons jiggle, click the x just like you would do on a device). Running again used the correct images.
回答8:
Running sudo rm -rf ~/Library/Application\ Support/iPhone\ Simulator/7.*/Applications fixed the problem for me. You might have to change the 7, depending on which version you'll have in ~/Library/Application Support/iPhone Simulator
