First of all, not sure if this thread belongs in this section, so move it if needed. sorry. Now to my problem. I used a very simple example from a book i just recently bought about developing using the Open Toolchain. It is supposed to just create a window and view and just display "hello world". The problem is that the app will not show up on the springboard, so it cannot be opened. I used Pwnage to jailbreak my 2.1 FW 2g iphone. I used: Code: arm-apple-darwin9-gcc -o MyExample MyExample.m -lobjc \ -framework CoreFoundation -framework Foundation -framework UIKit to compile the app (it compiled without a problem) I used: Code: scp -r MyExample.app root@iphone:/Applications to copy the app to the iphone (I can see the app in the right place using termainal) signed the app using: Code: ldid -S /Applications/MyExample.app/MyExample and finally: Code: killall SpringBoard to restart SpringBoard. all this worked fine, but the app does not show on the springboard, and thus cannot be tapped on to open it. Is there anything that I should have done differently? Is there something else that I need to do? All help is apopreciated.
