App Installs But Nothing Happens - Screen is Black - iOS / iPad

Getting Started Newbie Questions
#1

I can build for IOS and install on the device (iPad) but when I go to run the app the display is black.

During the build the only warnings (see below) I got was regarding the icon sizes even though the icons are the correct size.

I built with the latest stable release 704a, and also 807
I deleted the .DS_Store file from the directory and rebuilt
I built with both an Ad Hoc and a Developer provisioning profile

I’m working on a Macbook Pro running Snow Leopard 10.6.8
My device is an iPad 3 running iOS 5.1.1
I have xcode 4.2 installed
I don’t see any file name case sensitive issues

I can’t test (as of yet) in xCode because my device is IOS 5.1 and xcode 4.2 does not support IOS 5.1 on Snow Leopard - there’s now way I’m upgrading to Lion. I may try the hack listed elsewhere to get this to work.

Until then - any advice? I’m dead in the water right now.
Build Warnings:

warning: iPhone/iPod Touch: Icon.png: icon dimensions (0 x 0) don’t meet the size requirements. The icon file must be 57x57 pixels, in .png format (-19014)
warning: iPad: Icon.png: icon dimensions (0 x 0) don’t meet the size requirements. The icon file must be 72x72 pixels, in .png format (-19014)

Assumptions about where files might be.
Case sensitivity of filenames: the Mac file system isn’t case sensitive, but the iPad is.
>>there’s no way I’m upgrading to Lion<<
Why?

How about you try this out using a rented mac through MacinTheCloud?

(Although it won’t take long before you have spent more than the cost of a Lion upgrade doing so…)

@Jeff472

Thank you for your reply.
I already mentioned that I do not see file case sensitivity issues. In other words I checked this already.
I can’ t upgrade to Lion because it will slow down my machine and will require far too much time to get everything working again.
Since I already have a Mac I don’t see the point of Macinthecloud.

What would help is some feedback on what might actually be causing the problem other than file name case issues. I should be able to get this working with my existing system without much effort. Everything works great in the simulator.

Anyone?

Thanks

>>I already mentioned that I do not see file case sensitivity issues.<<
Yes, I missed that. But calm down.
I know its frustrating when stuff doesnt work.
>>I checked this already.<<
OK. That only says you havent noticed any, but lets take that on trust for now.
>>What would help is some feedback on what might actually be causing the problem<<

That was some.

Try the old standard:
Remove lots of code until it starts to work, then add chunks back in until it breaks.
Are you using Corona Project Manager?
It creates a temporary folder and launches from there, but if you have used an aliased file, maybe its missing from the final build.
Without an error message, everyone else has less idea of what the problem is than you do.

To build for the iPad 3 you need xcode 4.3.2 period. The solution I posted may or may not work for you on snow leopard, If your machine is capable of running lion just upgrade and save yourself the hassle and unpredictability of hacks.

I can’t see how lion will slow down your machine, I am running it also and it is no slower for me than snow leopard (it has come a long way since the initial release)

Also… you don’t *have* to do a fresh install of Lion, you can upgrade from snow leopard which will keep all your apps and settings intact. So there is 0 extra work bar just upgrading to lion [import]uid: 84637 topic_id: 27018 reply_id: 109683[/import]

Danny, I have to disagree about Lion not being slower. I just got my day job Mac upgraded to 8gb of memory to help with the performance problems. Many of the issues is with the OS and apps saving their last state instead of just shutting down, but the latest Lion patch now honors the don’t save my apps flag and that has helped boot up time and shutdown time considerably.

That said, while Lion is slower, its not “that much slower” once things are loaded and running and you’re not running out of memory. Maxing your memory out is a good thing and is cheap right now.

But if you want to build for iOS 5.1 you have to be on Lion with XCode 4.3, so you should go ahead and bite that bullet. It’s worth it.

Thanks guys. I did not know I needed xcode 4.3.2 for the iPad 3.
FWIW: My Macbook Pro is over 5 years old and maxed out at 4GB RAM - so given the computer’s age, CPU speed, and RAM, and too many years experience with computers, and numerous posts online about how upgrading to Lion slowed down their machines the upgrade path is not an option for me. I do have access to a Snow Leopard machine and so I’ll try that.

I tried running the app on my iPhone 4S but it will not even install. @Danny - does the iPhone 4S have the same requirements as the iPad 3?

@Jeff472 - thanks for the recommendations. Removing code was going to be my next step. I do not use Corona Project Manager but I also do not use aliased files.

Otherwise, from everyone’s responses can I assume the only known non-platform issue that can be causing the problem is file name case sensitivity issues?

FWIW, I use a Macbook 2.4hz with Lion and 4gb RAM.
Its fine by me unless I open a VMWare Fusion session too.

I just ran into another issue.

@Danny or anyone else - I tried loading the app on my old iPhone 3G but got the error message that it “… was not installed in the iPhone 3G because it requires a newer version of iPhone software.”

I assumed that when I build apps they will be backward compatible. How do we handle this?

The iPhone 3g isn’t supported anymore (apple move) [import]uid: 84637 topic_id: 27018 reply_id: 109736[/import]

#11

@Danny - Do you know if I can use Snow Leopard / xcode 4.2 to build for the iPhone 4s / iOS 5.1?

I seem to be having problems with this as well. Couldn’t find any compatibility matrices on Apple site.
