General tips for troubleshooting apps that work in the simulator but on device?

Getting Started Newbie Questions
#1

Just before I head off down the painful route of ripping code to pieces and re-enabling bit by bit, are there any general guidelines or tools available to diagnose this sort of problem?

I can run my app no problem in the simulator and there are no errors in the terminal at all.

I’ve tried it on a 3GS and iPad and I get a blank screen on both.

Look into the organizer log of Xcode first. If that doesn’t tell you anything, start the app via XCode instruments and check the console output there. [import]uid: 5712 topic_id: 3166 reply_id: 9355[/import]

Also make sure that

  • The file formats of your assets are supported on the device
  • That the casing of the file names is the same in your code, the simulator forgives that, the device not
  • On Android, don’t use equal filenames with different extensions. Because on Android, the file extensions will be cut off. [import]uid: 5712 topic_id: 3166 reply_id: 9357[/import]
