I have a Cocos2D game I want to install on my devices with Testflight. For any reason I only see a black screen when I start the project after installing via Testflight. It works fine on the simulator.
Here is the AppDelegate file: http://pastebin.com/KJwqq1us
Here is some of the code of the main menu: http://pastebin.com/9pE1drH1
The strange thing: When I add a viewController's view as a subview I see the view controller, but not the Cocos2d elements.
Would be awesome, if somebody could help me out with that problem :) Thanks in advance!
Edit:
When I install and run the game with Xcode it doesn't work as well. I tried to clean the project, delete the build folder. I create the ipa file by building for archiving -> archive -> use organizer to export as ipa file and upload this file directly to Testflight. Could the startup image cause a problem with the cocos2d layers? When I compile my application, no errors or warning are shown. No matter if I run it on the simulator in retina or non retina, it always works. On any real device it doesn't show anything related to Cocos2d like sprites or the menu
Here's a stab-in-the-dark answer as you haven't given enough details to go on....
Check the case of your graphics files and in your code match. Remember that the device IS case sensitive, but the simulator is NOT.
I fixed the blackscreen by updating the cocos2d framework to the latest beta version. I'm not sure what exactly was causing the problem

I am new to iPhone application development, and I am building a new calculator just to see how everything works.
I completed my code, but when I run the application, it does not show anything on the simulator.
I have created a number pad, but the screen is blank (white) after the application launches.
Can anyone give me a pointer, please?
I am using Xcode 4.2 and deployment target is 5.0
If you are using empty template for your project them make sure that you are correctly adding your view to window in appdelegate file in function named applicationDidFinishLaunching.
It can also happen when you target for iphone and using xid file related to ipad or another way.
hope it will help you and sorry for my bad english
I recently started using Xcode 4.2 and the iOS 5 simulator. When I update an older version of my app pre-installed in the simulator, it updates the app just fine but the app icon is not updated. Even with cleaning and building the app ahead of time (sometimes a couple of times) this seems to be the case. Is this a bug or am I doing something wrong?
EDIT: Still the same problem, but when I quit the simulator and start it again (NOT deleting the app), the icon is updated. That's a little encouraging at least. Has anyone else experienced this?
I've had this problem for a while and cleaning the project didn't work either. I finally found a trick to do this. It works at least in iOS 6, I'm not sure in previous versions. The trick is to simply move the app to a folder. The moment you move it there it should display the new icon, and then you can move it out again.
Despite others' answers, it would appear that your problem is a bug.
It would probably be wise to report this. Otherwise, try making a new project and trying again.
Hope all goes as planned.
Theres a new category in the plist file called Icons Files (iOS 5.0). Try adding those file names to your target info like so:
In this tab:
The names and size much also be exact. See this Apple Technical Q&A #1686:
57x57 - Icon.png
114x114 - Icon#2x.png
72x72 - Icon-72.png
50x50 - Icon-Small-50.png
29x29 - Icon-Small.png
58x58 - Icon-Small#2x.png
I ran into a similar problem after renaming the app and adding the Icon files category as described in one of the other answers. No icon would show up in either simulator or device. Tried a clean build as well as restarting simulator and Xcode, no success
The solution for me was to drag the icons from my Resources to the two empty wells under App Icons located under Targets -> Summary. After that my icons showed up in both simulator and device. I´m running Xcode 4.3.1
this works for me.
In iOS Simulator :
iOS Simulator -> Reset Content and Settings
Be aware that it removes all things from the simulator to the trash... but it does work.
Make sure of icons sizes are right at the Image Asset folder
I've just finished my app for iPhone and it is working fine. I now want to make the app universal but am getting a black screen when running it on the iPad simulator. Here is what I have done so far:
When electing to make universal, I allowed xCode to create my "-iPad" version of my main nib; Therefore, I have MainWindow.xib for iPhone and MainWindow-iPad.xib for iPad. I have checked my plist file and have confirmed that both entries are present
Have double checked each UI component in the new iPad version to make sure all connections are made identically to the iPhone version. I also double check that the classes are correct
I have made sure that the "visible at launch" and "full screen at launch" options are selected
I read somewhere that removing the "-" worked for someone and have tried renaming my nib and plist entries
I am assuming that my app would then load the proper nib. Obviously I'm either wrong or have some configuration not right
On the other hand, if I need to make some change in my didFinishLoadingWithOptions to force they selection between my nibs - well I must admit I don't know how to accomplish this either.
Thanks!
If the app doesn't crash, than it means it can find the black screen.
Truncating the cache is done in Product -> Clean and also what you could try is "Reset" on the iOS simulator.
Further more, what you could check is if the "view" is linked correctly in your nib. (see image).
OK, after much trial and error, I have gotten this to work; Although, I'm not quite sure which exact steps solved the problem, I have a sneaking feeling it was some of the settings I had for the versioning of the app.
I created a new test app for iPhone and then converted it to iPad. Of course this worked unlike my app. I then compared everything I could think of between the apps. I changed the supported version from 3.1 to 4.0 on the Target -> Summary tab. I then check my build settings and changed everything in there to 4.0 as well. Finally, for each .xib file I set the deployment to "Project SDK Version (iOS 4.3) and the Development to "Interface Builder 3.1" because that is what my test app was set to. To be honest, I don't even recall altering these or do I really even know if this has an impact all I know is that I did change them as described. Did a project clean, reset the simulator and now it is working. I'm wondering if it was the 3.1 was too early for the iPad...
Anyway thanks.
I just upgraded to iOS 4.1 SDK and now when I run my app in the simulator one of the images (the only one really) that was working fine before the upgrade is no longer showing up in my view. I've tried removing the file and re-adding it to the project, cleaning all targets and running a build, and making changes to the XIB where the UIImageView is configured to for it to recompile it, but no dice. It's worth noting that my Tab-Bar images came through just fine. Any ideas?
If the UIImageView is created inside a .xib, open it up in Interface Builder: can you see the image in the "preview"? If not, then it can't find the image to begin with. Perhaps the file has been renamed?
Look inside the application bundle in the Finder. Is your image file present? If not, is it still referenced in your project? Check Xcode to make sure the file name isn't in red (i.e. missing).
Maybe they've changed the 4.1 simulator to be (or rather, pretend that the filesystem is) case-sensitive?
Does the app work on a 4.0 device?
I just updated to iPhone SDK4. The problem I am facing is - I was writing an app in iPhone sdk 3.0 just open that project in xcode 3.2.3 made some changes in xib file, now when i run this project in simulator the user interface (xib) appearing blank (with black color).
Any idea why this is happening...?
Thanks

You may be trying to run directly from IB (with cmd+R) this makes it only load the view you're currently editing and does something similar to what you're describing. Save, switch to xcode and run from there, see if that helps. :)
