iPhone Debugging: Get a black screen when debugging a universal app -

-

i working on universal app (4.0.1 sdk) , unable run on ipod touch. works on ipad, , on both ipad simulator , ipod simulator when try launch app on touch, main gets called , can stop @ break point (i assume means provisioning , certs right) nothing after that. there isn't in gdb log. can debug simple "hello world" type app on touch. have suggestions of else try?

  1. if not using .nib files might want make sure code creates window gets executed: window = [[uiwindow alloc] initwithframe:[[uiscreen mainscreen] bounds]];

  2. if using .nib (.xib) files make sure have window appropriately delegated app delegate in interface builder.

in case subclassing app delegate , accidently removed line calling [super didfinishlaunchingwithoptions...] window being created.

i hope helps someone.

cheers
